Material price and basic knowledge of cemented carbide rods [carbide rods]

Cemented carbide is the most widely used type of high-speed machining (HSM) tool material. This type of material is produced by powder metallurgy. It consists of hard carbide (usually tungsten carbide WC) particles and a softer metal bond composition.At present, there are hundreds of WC-based cemented carbides with different compositions. Most of them use cobalt (Co) as a binder. Nickel (Ni) and chromium (Cr) are also commonly used binder elements, and other elements can be added. Some alloying elements.

(1) Simple cemented carbide grades

Such grades used for metal cutting usually contain 3%-12% cobalt (weight ratio).The size range of tungsten carbide grains is usually between 1-8m.Like other grades, reducing the particle size of tungsten carbide can increase its hardness and transverse rupture strength (TRS), but it will reduce its toughness..The hardness of simple grades is usually 89 to 93.Between 5HRA; the transverse rupture strength is usually 1.2-2.Between 4MPa (175-350ksi).The powder of this type may contain a large amount of recycled raw materials.

Simple grades can be classified into C1-C4 in the C grade system, and can be classified according to the K, N, S and H grade series in the ISO grade system.Simple grades with intermediate characteristics can be classified as general grades (such as C2 or K20), which can be used for turning, milling, planing and wok processing; grades with smaller grain size or lower cobalt content and higher hardness can be used Classify as finishing grades (such as C4 or K01); grades with larger grain size or higher cobalt content and better toughness can be classified as roughing grades (such as C1 or K30).

Tools made with simplex grades can be used for cutting cast iron, 200 and 300 series stainless steel, aluminum and other non-ferrous metals, high temperature alloys and hardened steel.Such grades can also be used in non-metal cutting fields (such as rock and geological drilling tools), and the grain size of these grades is in the range of 1.5-10m (or larger), cobalt content is 6%-16%.Another non-metal cutting application of simple cemented carbide grades is to make dies and punches. These grades usually have a medium-sized grain size with a cobalt content of 16% to 30%..

(2) Microcrystalline cemented carbide grades

Such grades usually contain 6% to 15% cobalt.During liquid phase sintering, the added vanadium carbide and/or chromium carbide can control the growth of grains, thereby obtaining a fine grain structure with a grain size of less than 1m.This fine grain grade has very high hardness and 3.Transverse breaking strength above 45MPa (500ksi).The combination of high strength and sufficient toughness enables such brands of tools to adopt a larger positive rake angle, which can reduce cutting force and produce thinner chips by cutting rather than pushing metal materials.

Through strict quality identification of various raw materials in the production of grade cemented carbide powder, and strict control of sintering process conditions to prevent the formation of abnormal large grains in the microstructure of the material, appropriate Material properties.In order to keep the grain size small and uniform, the recycled recycled powder can only be used when the raw materials and recycling process can be fully controlled, and extensive quality inspections are implemented..

Microcrystalline grades can be classified according to the M grade series in the ISO grade system. In addition, the other classification methods in the C grade system and the ISO grade system are the same as the simple grades..Microcrystalline grades can be used to manufacture tools for cutting softer workpiece materials, because the surface of this tool can be processed very smoothly and can maintain extremely sharp cutting edges.

Microcrystalline tools can also be used to process nickel-based super alloys, because this tool can withstand cutting temperatures as high as 1200C.For the processing of high-temperature alloys and other special materials, the use of microcrystalline brand tools and ruthenium-containing pure brand tools can simultaneously improve its wear resistance, deformation resistance and toughness.Microcrystalline grades are trapped and combined to manufacture rotating tools (such as drills) that generate shear stress.There is a drill bit made of composite grades of cemented carbide. The cobalt content in the material is different in a specific part of the same drill bits, so that the hardness and toughness of the drill bit are optimized according to the processing needs..

(3) Alloy type cemented carbide grades

This type of grade is mainly used for cutting steel parts, and its cobalt content is usually 5% to 10%, and the grain size range is 0.8-2m .By adding 4% to 25% of titanium carbide (TiC), the tendency of tungsten carbide (WC) to diffuse to the surface of steel chips can be reduced.By adding no more than 25% of tantalum carbide (TaC) and nickel carbide (NbC), the strength, crater resistance and thermal shock resistance of the tool can be improved.Adding such cubic carbides can also improve the red hardness of the tool, and help avoid thermal deformation of the tool in heavy cutting or other machining where the cutting edge will generate high temperatures..In addition, titanium carbide can provide nucleation sites during the sintering process to improve the uniformity of cubic carbide distribution in the workpiece.

Generally speaking, the hardness range of alloy type cemented carbide grades is 91-94HRA, and the transverse fracture strength is 1-2KPa (150-300ksi).Compared with simple grades, alloy grades have poorer wear resistance and lower strength, but they have better bond wear resistance..Alloy type grades can be classified into C5-C8 in the C grade system, and can be classified according to the P and M grade series in the ISO grade system.Alloy grades with intermediate characteristics can be classified as general grades (such as C6 or P30), which can be used for turning, tapping, planing and milling.The grades with the highest hardness can be classified as finishing grades (such as C8 and P01) for finishing turning and key cutting.These grades usually have smaller grain size and lower cobalt content to obtain the required hardness and wear resistance.However, similar material properties can be obtained by adding more cubic carbides.The toughest grades can be classified as roughing grades (such as C5 or P50).These grades usually have a medium particle size and a high cobalt content, and the addition of cubic carbides is also small, in order to obtain the required toughness by suppressing crack propagation.In intermittent turning, the cutting performance can be further improved by using the cobalt-rich grades with higher cobalt content on the tool surface..

Alloy grades with lower tungsten carbide rods content are used for cutting stainless steel and malleable cast iron, but can also be used for processing non-ferrous metals (such as nickel-based super alloys).The grain size of these grades is usually less than 1m, and the cobalt content is 8%-12%.Grades with higher hardness (such as M10) can be used for turning and machining malleable cast iron; grades with better toughness (such as M40) can be used for milling and planing steel, or for turning stainless steel or super alloys.

Alloy-type cemented carbide grades can also be used for non-metal cutting purposes, mainly for the manufacture of wear-resistant parts.The grain size of these grades is usually 1.2-2m, cobalt content is 7%-10%.In the production of these grades, a large proportion of recycled raw materials are usually added to obtain higher cost-effectiveness in the application of wear-resistant parts.Wear-resistant parts need to have high corrosion resistance and high hardness. When producing such grades, these properties can be obtained by adding nickel and chromium carbide.

In order to meet the dual requirements of tool manufacturers in terms of technology and economy, cemented carbide powder is a key element.The powder material designed for the processing equipment and process parameters of the tool manufacturer can ensure the performance of the finished workpiece and lead to the appearance of hundreds of cemented carbide grades.The recyclable characteristics of cemented carbide materials and the ability to directly cooperate with powder suppliers enable tool manufacturers to effectively control their product quality and material costs.

Masonry Drill Bits,Tungsten Carbide Drills

The masonry drill bits here are a variation of the twist drill bits. The bulk of the tool is a relatively soft steel, and is machined with a mill rather than ground. An insert of tungsten carbide is brazed into the steel to provide the cutting edges.

Masonry drill bits typically are used with a hammer drill. The bit is both rotated and hammered into the workpiece; the hammering breaks up the masonry at the drill bit tip, and the rotating flutes of the drill bit body carry away the dust. Rotating the bit brings the cutting edges onto a fresh portion of the hole bottom with every hammer blow. Hammer drill bits often use special shank shapes such as the common SDS type.

Masonry drill bits of the style shown are commonly available in diameters from 5 mm to 40 mm. For larger diameters, core bits are used. Masonry bits up to 1000 mm (39") long can be used with hand-portable power tools, and are very effective for installing wiring and plumbing in existing buildings. A star drill is a hand powered drill used in conjunction with a hammer to drill into stone and masonry. A star drill's cutting edge consists of several blades joined at the center to form a star pattern.

It is not easy to drill holes into concrete blocks, bricks, or stone as well as quarry tiles. Heavy-duty drill bits are required to do the job well and with precision. And the best bits to do this job are the masonry drill bits. These drill bits are available in various types.

There are masonry drill bits that have twists in order to help in drilling into steel as well as other hard metal. There are other types of masonry drill bits which are used in hammer drill in order to drill hard materials. This bit hammers the material and after that, it rotates into the work piece. While hammering, the masonry gets broken at the tip of the drill bit. Now the flutes of the masonry drill bit carry away the dust drilling it into the work piece and then rotating bit hammers its way to the masonry in order to give it a smooth edged hole.

The common masonry drill bits are the ones with SDS shanks. They have spring-loaded chuck which helps the bit to chuck with a quick hand-action. This is essential for drilling these bits into masonry. You may find masonry drill bits made of silicon bronze alloy as the cutting point. This is especially good in case you wish to do some heavy-duty drilling.

These are also called as durium tips and are easily available at any hardware store. Such masonry drill bits are very popular with contractors, construction workers and used for other commercial purposes. Such bits are used in power drills as those drills are used for heavy woodworking or metal drilling. And in case cheap quality drill bits are used, the hammering action can result in shattering the bits.

It is always better to opt for low rotation speed while you drill hard materials as high speed drilling could lead to overheating the masonry drill bits making them break the tip. And keep on pulling out the bit in order to brush off dust to ensure that you have a continuous smooth drilling action.

These drill bits are available in various different sizes ranging from 5mm in diameter up to 40mm. And in case of drilling through masonry walls, bits measuring from 300 to 400mm are used in order to drill efficiently. These are extra long masonry drill bits which should be handled with care. Hence, such a drill bit is typically used by construction workers who have expertise in using such drills as well as bits. Tungsten carbide tip is also quite popular; and they are bound to spiraled steel shafts. These tips are quite durable and can be sharpened with the help of a drill sharpener or a grindstone. This should be done occasionally in order to get the maximum effect of drilling with these drill bits. A masonry drill bit can be quite helpful when you wish to drill through concrete blocks or bricks around your house.

Can copper tungsten alloy rods be used as touch solder pins [carbide rods]

What touch solder pin?Are you talking about resistance spot welding electrodes?It is best to use chromium-zirconium-copper, a high-temperature resistant alloy, which does not soften at high temperatures and is resistant to wear

Tungsten copper alloy is an alloy composed of tungsten and copper.The copper content of common alloys is 10%-50%.The alloy is prepared by powder metallurgy, which has good electrical and thermal conductivity, good high temperature strength and certain plasticity.At very high temperatures, such as above 3000C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat, and reducing the surface temperature of the material.So this kind of material is also called metal sweating material.

Tungsten copper composite material is a two-phase structure pseudo alloy mainly composed of tungsten and copper elements, and is a metal matrix composite material.Because the physical properties of copper and tungsten carbide rods are quite different, they cannot be produced by the fusion casting method, and are generally produced by powder alloy technology..

Tungsten copper alloy has a wide range of uses, most of which are used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries.Secondly, it is also used to manufacture high-temperature components such as the contacts of high-voltage electrical switches that are resistant to arc ablation, rocket nozzle throat linings, and tail rudders, as well as electrodes for electrical machining, high-temperature molds, and other applications that require electrical and thermal conductivity and high-temperature use. occasion.
