Brightray Alloy F is a Ni-Fe-Cr electrical resistance alloy with high iron for resistance to internal oxidation. Brightray Alloy S is a nickel-chromium alloy similar to Brightray C (Alloy Digest Ni-355, February 1988) but without rare earth alloy additions. Both alloys are used in industrial furnaces. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on high temperature performance as well as forming. Filing Code: Ni-644.
