Cobalt-based Alloy Powder (Co-B) Description
Cobalt-based alloy powder is produced by melting suitable amount of tungsten and carbon or molybdenum into the cobalt-chrome alloy for strengthening. As carbon has low solubility in cobalt, there will generate WC, W2C, W6C and other carbides, which keep the alloy maintain excellent intension and rigidity under high temperature (800°С).
