Within the Tungsten family, the main purpose of Cobalt is that of a binder with Tungsten to make Tungsten Carbide.
Outside of Tungsten Carbide, Cobalt is widely used as an alloy with various types of other metals to create Cobalt Superalloys. Such items include All Stellite Grades, Elgiloy, F75, L605, HS Star J, Mar M 247, Mar M-322, Mar M-509, Mar M-918, FSX 414 & MP35N.
These Cobalt alloys listed above are examples of more common alloys while many other grades of Cobalt Superalloys exist.
