NI SPAN C Alloy 902

Ni Span C902 Sheet 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.

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.
