C95800 Nickel Aluminum Bronze (NiAlBr) is the highest strength standard copper based alloy. All aluminum bronzes can be heat treated, further increasing tensile strengths. C95800 is Copper Alloy UNS number in ASTM B148 and ASMT B505 for casting purpose. This material is mostly suitable for large size castings, particularly high in strength, and good performances in corrosion resistance and abrasion resistance.

Nickel Aluminum Bronze C95800 Casting Heat treatment process:
For better carrion resistance in seawater application, castings in copper alloy UNS No C95800 may be given a temper anneal heat treatment at 1250+/-50°F [675+/-10°C] for 6 hour minimum, generally followed by air cooling. Cooling shall be by the fastest means possible that will not cause excessive distortion or cracking, propeller castings shall be exempt from this requirement
Corrosion inhibiting heat treatment is option.
