BRONZE ALUMINUM NICKEL ALLOYS

Bronze Al Ni alloys, they feature excellent mechanical properties and abrasione and wear resistance. The addition of Ni increases the corrosion resistance without loss of other main properties of the alloy.
Balls are provided in the passivated condition.
Applications
Special pumps and valves for applications in the aerospace, automotive and marine fields.

Corrosion Resistance
Bronze Al Ni alloys are indicated for seawater applications. They feature good stress corrosion cracking and corrosion fatigue resistance. They are not affected by chloride pitting. They are attacked in enviroments containing hydrogen sulfide.
