Cobalt Molybdenum (CoMo) Master Alloy

The cobalt-molybdenum master alloy provides a very convenient means for adding molybdenum to cobalt base alloys (e.g. stellites). It offers the advantage of both a lower melting point and a lower density than molybdenum itself which melts at 2610°C and weighs about 10.2 g/cm3.

Cobalt Molybdenum achieves solid solution strengthening, precipitation hardening, complex carbide formation in cobalt based superalloys.


The following table provides the form and composition of the CoMo50 master alloy:
