We are indulged in making, exporting, distributing and supplying of Copper Tungsten Contacts in Shenzhen, Guangdong, China. Copper tungsten composite has tungstenâs advantage of wear resistance and copperâs advantage of high electrical conductivity. So it is the good material for produce the electrical contacts.
We use vacuum infiltration prcoss produce the CuW contact tips. Our tungsten copper alloy and the AgW, CuWC, AgWC pass through the air-content test. That O2<50ppm, N2<20ppm, H2<5ppm. The test result shows our product can fully suitable for the Oil cut transformer(SF6), vacuum middle and low voltage switch. Our copper tungsten properties comply with ASTM B702.
HOSOMTAL has two kinds of contacts
pure copper tungsten electrical contacts
CuW-faced join with copper, CuCrZr shank electrical contacts
