CORROSION RESISTANCE OF COBALT Available to Purchase

In spite of the present importance of cobalt, relatively little information is available on the resistance of this metal to corrosion. Probably the main reason for the paucity of data on this subject is that, although the corrosion resistance at elevated temperatures of several cobalt‐base alloys is outstanding, cobalt is not utilised to any appreciable extent in its unalloyed condition, owing to the greater abundance and lower price of its sister metal nickel.
