60+ Years of Innovation
Alloy Development
Cannon-Muskegon began cast superalloy modification work in the late 1970s with CM 247 LC® alloy (Rene’ 108), a DS derivative of MAR M 247 alloy.
Excellent Castability, Strength and Ductility
Because of the excellent cast-ability, strength, and ductility (including fatigue properties) of CM 247 LC®, it has been used since 1984 for flight and industrial engine blades, integral axial turbine wheels, and high performance turbocharger wheels (Formula 1 racing) by at least 14 OEMs worldwide.
Work on single crystal (SX) alloy development began in the late 1970s, inspired by the pioneering SX alloy and casting process developments at PWA. This has led to the following CMSX® alloys:
