Scope

This specification covers a cobalt alloy in the form of wire, rod, strip, foil, and powder and a viscous mixture (paste) of powder in a suitable binder. This filler metal has been used typically for joining cobalt alloys requiring corrosion and oxidation resistant joints with good strength at elevated temperatures, but usage is not limited to such applications.
