Product Overview:
The Copper tungsten material products are highly resistant to heat, electric arc, wear and deformation at high temperature welding, flash butt and spot welding. Copper Tungsten alloy has excellent electrical and thermal conductivity with low thermal expansion, good thermal and electrical conductivity, excellent arc resistance, superior wear resistance and strength at elevated temperatures.
Copper tungsten alloy contacts Details
What is a copper tungsten alloy contact?
Copper tungsten alloy contacts are a type of composite material that utilizes the characteristics of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder. The tungsten powder is first pressed and formed, then sintered at high temperature, and then dissolved into the tungsten framework.
The characteristics of tungsten copper contacts:
Tungsten copper contacts have excellent resistance to arc burning and welding, good arc breaking performance, good conductivity and thermal conductivity, small thermal expansion, high temperature non softening, high strength, high density, high hardness, and other characteristics. It has good conductivity and thermal conductivity, good high-temperature strength, and a certain degree of plasticity.
The use of tungsten copper contacts:
Electrical contacts are important components in high and low voltage electrical switches and instruments, responsible for connecting and disconnecting circuits, as well as carrying the corresponding current in the circuit. Tungsten copper electrical contact materials have been widely used in automatic switches, universal circuit breakers, and molded case circuit breakers. Tungsten and copper do not dissolve with each other and do not form intermetallic compounds. As tungsten copper alloy is a material uniformly mixed with its two monomers, we call it a "pseudo alloy". Tungsten copper alloy materials have both the high temperature resistance, high hardness, and low coefficient of expansion of tungsten, as well as the high conductivity, thermal conductivity, and good plasticity of copper. Our company produces copper tungsten alloy contact products year-round, and 80% of tungsten copper alloys are sold overseas. The product quality is stable, the supply is timely, and the price is favorable. We produce tungsten copper alloys in a variety of shapes, including tungsten copper alloy rods, blocks, bars, sheets, discs, and customized according to customer drawings or needs.
