BRIGHTRAY alloy C is an 80 20 nickel chromium alloy containing long-life additions which make it suitable for applications subject to frequent switching and wide temperature fluctuations. It may be used at operating temperatures up to 1150 C (2100 F). It has a relatively low temperature coefficient of resistance coupled with high resistivity. This datasheet provides information on composition, physical properties, and tensile properties. Filing Code: Ni-355. Producer or source: Inco Alloys International Inc..
