55W45Cu Tungsten Copper Alloy Material

55W45Cu tungsten copper alloy is an alloy made of 55% tungsten and 45% copper composition. Preparation of alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, the alloy of copper is liquefied and evaporated to absorb a lot of heat, reducing the surface temperature, so these materials are also referred to as metal sweat material.

55W45Cu tungsten copper alloy electrical materials: mainly divided into electrical contact materials and electrical processing materials.
(1) Electrical contact materials. This is the most important class of electrical materials, they have a high resistance to arc erosion resistance and welding performance, for a variety of high and low voltage electrical switches and some instruments as electrical contacts, electrical contacts and electrodes. Tungsten copper electrical contacts is the largest application category, especially copper content of 20% to 40% tungsten copper largest application, mainly used in high voltage and the high current switch appliances, Example output protection grid circuit breaker contacts and other contacts, contacts.

(2) The EDM material. It refers to the resistance welding, electric riveting, electric upsetting, EDM electrodes and the mold material. EDM requirements electrode or mold material with good electrical conductivity and resistance to arc erosion resistance, in order to ensure accuracy, so the use of tungsten copper, resistance welding are mostly copper tungsten material, electric riveting and upsetting power in a under some occasions tungsten copper materials.
