Copper Tungsten Contacts

​We are pioneers in the manufacture of high voltage Copper Tungsten Contacts and arc resistant contact materials. The Copper Tungsten Contacts material is hard and durable, has good electrical conductivity, and is especially resistant to the erosion and damage of the contact arc. We use the vacuum infiltration process to produce the CuW contacts. Our tungsten copper alloy and AgW, CuWC, AgWC passed the air content test. O2<50ppm, N2<20ppm, H2<5ppm. The test results show that this product is completely suitable for oil-cut transformers (SF6) and vacuum medium and low voltage switches. Our copper tungsten properties meet ASTM B702.

Copper Tungsten Contacts material is a composite material of tungsten and copper. Tungsten copper material has both the low expansion characteristics of tungsten and the high thermal conductivity of copper

We can produce tungsten-copper contacts according to customer's drawings in shapes such as rods, rods, plates, blocks and tungsten-copper alloy parts. Copper-tungsten electrode Walter, Walmer machine, copper-tungsten electrical contacts.

We supply: 65%w-35%copper, 70%w-30%copper, 75%w-25%copper, 80%w-20%copper material

Copper-tungsten contacts are used in SF-6 circuit breakers, load switches, transformer cascade switches, resistance electrodes and spark erosion electrodes​
