Nickel Alloy - Cupro-Nickel (Copper-Nickel)

Alloy 500


Alloy 500 is a precipitation hardenable copper nickel alloy, with minimum 63% Nickel and the addition of titanium and aluminium that can be heat treated to give very high strength. The alloy has similar corrosion resistance to alloy 400 in a wide range of media including seawater, hydrofluoric acid, sulfuric acid and alkalies.

This alloy is supplied hot worked and aged (with cold worked mechanical properties)

Bars 1 inch to 4 inch diameter are supplied with 3.2 Certification.

Bars are UT tested to DEF STAN 02-729

All bars are of European Origin.
