Cobalt Chrome Alloy Powder (Co-Cr-W) 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).

Cobalt-based Alloy Powder Properties
Cobalt-chromium alloy primarily consists of cobalt and chromium. Tungsten, molybdenum, and minute amounts of silicon, manganese, and iron are present as well. Cobalt serves to harden the alloy and add hardness. Chromium is employed to lower the melting point and improve corrosion resistance. Silicon and manganese are used for deoxidation. They improve the fluidity of the alloy as well.
Compared to precious metal alloys and nickel-chromium alloys, cobalt-chromium alloy possesses superior physical properties. It offers excellent corrosion protection and biocompatibility. It is also less expensive. Because of these advantages, it has remained a crucial material for dentistry and medical orthopedics for decades.
