Meehanite GA350 is a heat-treatable, pearlitic gray cast iron that exhibits high strength while still maintaining good thermal conductivity and good machinability. It is generally used for applications where the thermal conductivity requirements preclude the use of other higher-strength materials such as spheroidal graphite cast irons, which have inferior thermal properties. This datasheet provides information on physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on high temperature performance as well as casting, heat treating, machining, and joining. Filing Code: CI-72. Producer or Source: Meehanite Metal Corporation.
