About Ni Span C902

Ni Span C902 is a precipitation hardenable Ni-Fe alloy attaining controlled thermoelastic coefficient and static elastic modulus at temperatures from -50oF to 150oF. The main constituents of alloy are iron, nickel and chromium with nominal traces of titanium and aluminum.  It produces a reddish brown oxide layer upon exposure to natural conditions and has nominal expansion after hot and cold processing.

Low magnetosrictive properties of alloy 902 are useful in applications such as delay lines. The room temperature magnetization value for this metal is 5000 gauss. Its permeability can be significantly altered by cold and hot processing. It offers small mechanical hysteresis.

Industrial Nomenclatures: Ni Span C902, Ni Span C 902, Alloy 902,  AWS 080, UNS N09902

Ni Span C902 Specifications: SAE AMS 5221, AMS 5223, AMS 5225, AMS 5210, BS 3127

Ni Span C902 Applications

Precision Springs, mechanical resonating devices, precision elastic parts, helical and leaf springs, diaphragms

Ni Span C902 Fabrication

Alloy C902 is hardened by cold and hot processing. It can be joined through welding, brazing and soldering. The brazing should be done in heat processed form to avoid rupturing. For the great welding results, it is welded by using the techniques similar to stainless steels. Autogeneous inert gas fusion welding is preferred. While joining process, the temperature and period of joining should be taken into account because of its influence on the thermoelastic properties of the material.
