Copper-Nickel Alloys - Marine Supreme: Applications Information

Copper Applications in Metallurgy of Copper & Copper Alloys

June 2000

There are many useful articles covering the advantages of the copper-nickel alloys for use in many applications and the best way in which they can be used. This table summarizes the information freely available on the Copper Pages sponsored by international copper industry and supplied by CDA Inc (USA) and CDA (UK).
