Rotelloy 5 nominally contains 50% Co and has been specially developed as a high-strength rotor material for machines operating at high speeds. The alloy is less suitable for stator applications since it has higher losses than Rotelloy 3. In some cases, this can be overcome by the use of thinner strip. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on high temperature performance as well as heat treating and machining. Filing Code: FE-129. Producer or source: Carpenter Technology Corporation.
