Can copper tungsten alloy rods be used as touch solder pins [CNC Carbide Inserts]

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.

Hao Carbide With Alloy Bar [CNC Carbide Inserts]


Monel alloy, mainly composed of nickel (up to 67%) and copper, has a certain amount of iron and other trace elements. Monel is a binary alloy with the same ratio of nickel and copper, naturally found in the nickel mine from the *Bury (Ontario) mine by David H.Brown, metallurgist International Nickel Company Monel 401 was created. Monel was appointed president of the company after Monel, and obtained a patent in 1906. [2] Among them, L was dropped because the surname was not allowed as a trademark at the time.

Attributes:

Compared to steel, Monel is a very difficult machine because it hardens very quickly.. It needs to be opened and worked at low speed and low feed rate. It is resistant to corrosion and acid, and certain alloys can withstand fire in pure oxygen. It is usually used in applications with high corrosive conditions. Adding a small amount of aluminum and titanium to form an alloy (K-500) has the same corrosion resistance, but has greater strength, due to the formation of aging phase. Monel is usually more expensive than stainless steel .

Monel 401 has 8.83 specific gravity, about 34% conductivity IACS, and (in annealed state) 65 Rockwell B hardness


Aerospace applications:

In the 1960s, Monel alloy was found to be widely used in aircraft structures, especially in the production of frames and skin test rocket aircraft, such as the X-15 in North America, to resist the huge heat generated during aerodynamic friction. The temperature is very high. Speed flying. Monel retains its strength at very high temperatures, allowing it to maintain its shape and flying speed in a high-temperature atmosphere, adding a trade-off density to the weight of components due to Monel's high .

Marine applications:

The corrosion resistance of Monel alloy makes it very suitable for offshore applications such as piping systems, pump shafts, sea valves, drag wires, and filter baskets. These alloys are completely non-magnetic and are used for minesweeping on anchor ships. [4] For shell magnetic field measurement equipment. In recreational boats, Monel wire is used to hold the anchor rod, Monel alloy, used in water and fuel tanks, and used in underwater applications. It can also be used for propeller shafts and keel bolts.

However, due to the problem of electrolytic salt water (also known as action galvanic corrosion), in shipbuilding Monel must be carefully insulated from other metals such as steel. On August 12, 1915, he published an article about a 215-foot-long yacht, "That was once the first ship built with a complete Monel alloy hull" in just six weeks.Tungsten Carbide Rods had to be abandoned, "is considering the disintegration of her bottom by electric action.The steel frame of the yacht deteriorated due to the interaction with Monel electrolysis. [5]

Especially in seabird research and bird banding or ringing, Monel alloy has been used to make many species of bird bands or rings such as albatross live in corrosive seawater environments.

Monel alloy is also used in AVIC wiring safety to ensure that fasteners cannot be undone.

Corrosion rate is less than 0.025MM/A.High temperature corrosion: The maximum temperature of MONEL400 continuous working in air is generally around 600 , in high temperature steam, the corrosion rate is less than 0.026MM/A.Ammonia: Due to the high nickel content of MONEL400 alloy, it can withstand corrosion under anhydrous ammonia and ammoniating conditions below 585.MONEL400 alloy is a multi-purpose material, seamless water pipes and steam pipes in power plants.Sea water exchanger and evaporator.And environment.Crude oil distillation.Pump shaft and propeller of equipment used in deep sea water.Equipment for making uranium extraction and isotopic separation.Monel alloy, mainly composed of nickel (up to 67%) and copper, has a certain amount of iron and other trace elements.Monel is a binary alloy with the same ratio of nickel and copper, naturally found in the nickel mine from Bury (Ontario) by DavidH.Brown, metallurgist International Nickel Company Monel 400 was created.There are two types: processing-enhanced type, such as MonelR405, and precipitation hardening type, such as MonelK.The mechanical properties of commonly used Monel401 and K-MonelK-500 are better than Monel401, but the corrosion resistance is slightly worse.MONEL alloy is a nickel-copper corrosion-resistant alloy with excellent physical properties of high strength, high corrosion resistance and wear resistance.Belongs to the patented product of SMC Super Alloy Group.There are two types: processing-enhanced type, such as MonelR405, and precipitation hardening type, such as MonelK.The mechanical properties of commonly used Monel401 and K-MonelK-500 are better than Monel401, but the corrosion resistance is slightly worse.Monel401 plate can be called Monel401 stainless steel plate, Monel401 steel plate, Monel401 coil, Monel401 open plate, Monel401 strip steel, Monel401 cold rolled plate, Monel401 hot rolled plate, Monel401 thin plate, Monel401 medium plate, Monel401 thick plate, Monel401 extra thick plate Wait.The chemical composition of the alloy is roughly the same as Monel 400, the biggest difference is that it contains 2.3-3.15% AL and 0.30-1.00% Ti.The structural characteristics of this alloy are in addition to the diffused NI3 (AL.TI) Same as Monel 400 alloy except for precipitation phase.Generally, the corrosion resistance of Monel 500 in solid solution is basically the same as that of Monel 400 alloy. Therefore, the corrosion resistance data of Monel 400 can be used for Monel 500 alloy because of its low corrosion rate in flowing seawater. And the high strength of the alloy, therefore, the alloy is particularly suitable for manufacturing seawater corrosion-resistant centrifugal pump shafts.MONEL500 This alloy is mainly used in pump shafts, valve stems, conveyor scrapers, oil well drill rings, elastic parts, valve pads, etc., and is suitable for petroleum, chemical, shipbuilding, and electronic sectors..Seamless water pipes and steam pipes in power plants.Sea water exchanger and evaporator.
