Copper Brush Wire

The copper brush wire and tinned copper brush wire is widely suitable for mannufacturing brush Products, our copper brush wire is made by high pure cathode copper rod, product proferties is much better than the original one. To solve the brush pressing sintered at high temperature wire brush brittlet fracture problem.

Brush wire products standards:GB12970.4 Brush wire product type: TS, TSX, TSR

1.The finished brush wire is stranded by the right-direction
