C63000 - Copper Alloys

An American nickel aluminium bronze where its unique combined properties of high strength, good fatigue, excellent corrosion resistance in sea water, non sparking and wear properties makes it a popular choice across the whole spectrum of industry.

It has very high anti galling properties when running against most grades of steels and is used on a world basis for aerospace landing gear bushes and bearings where its strength, fatigue, wear properties, shock resistance and corrosion resistance are well proven.
