Available in solid bar - AMS 4640
Nickel Aluminum Bronze contains 5% nickel and is heat treatable.

Available in both rod and forged form, it is intended for applications that

require combinations of corrosion resistance, excellent bearing properties

at considerable loads, and extremely high strength both at room and

elevated temperatures.

C63000 has good resistance to sulphuric, hydrochloric and other non-oxidizing acids, as well as salt water and brackish waters. Its superior erosion and

cavitation properties facilitate use in pump and propeller applications. Retention of properties together with good oxidation resistance at elevated

temperatures make C63000 suitable for service in internal combustion engines, steam plant applications and chemical processing applications. Very little

deterioration takes place below 600° F and oxidation is retarded up to 1200° F by an oxide film. C63000 is very resistant to stress corrosion cracking in

numerous applications. Galling is a common problem designers have to overcome when choosing materials. Affinity between two mating metallic

surfaces can easily introduce galling when exposed to large bearing pressures and extreme temperatures. C63000 has great galling resistance, making it

the material of choice for such applications.

Not suitable to be cold worked. C63000 can be easily hot worked in the temperature range of 1450°-1700° F.
