Tungsten copper contact, the contact, the static contact and moving contact head And treatments by vacuum melting metal contact matrix and copper surface infiltration method, the surface is to rely on tungsten and copper in two element diffusion, a combination of both strength is very high, under the effect of high temperature arc not cracking (40.5 KV 630 a, arc temperature about 3000 degrees Celsius).Base (tungsten copper, copper tungsten carbide) as arc ablation resistance of the working face, achieve the composite of two different materials.
Tungsten-base composite material preparation of the characteristics of the electric contact: copper, tungsten carbide, tungsten copper metal tungsten or tungsten carbide as a skeleton, skeleton and copper filling in the pores of composite material, its high melting point skeleton strength, to ensure that the contact pressure arc ablation, copper not only improve the conductive, thermal conductivity and improved processing performance, and can absorb a large number of arc heat when arc heat evaporation, to improve the conditions of use and to reduce the galvanic action.
Tungsten copper electrical alloy with high density, high thermal conductivity, high strength and hardness, low resistivity, low thermal expansion coefficient, and the burning of the arc resistance, resistance to welding, such as electric corrosion resistance performance of applications in electrical contact materials and electrode materials has the advantage of other material can't fill in the short term. Tungsten copper composite contactor
HOSO Metal Co., Ltd from material to finished product, including the development of new materials and so on various products manufacturing stages are completed by our own factory.As a result, and treatments of metal can provide you with the most excellent service.
