Cobalt-Chromium Alloy cobaltalloy consist of complex carbides in an alloy matrix. Their exceptional wear resistance is due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a CoCr alloy matrix. Cobalt Saw Tips cobaltalloy are made of CoCrW alloy in grade Co12,so the following information is all about Co12. (1). CoCrW could be considered an intermediate alloy . ...
