View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.MEEHANITE type GM is a high strength iron which may be cast uniformly solid regardless of casting size or sectional deviation. This particular engineering material possesses true elastic properties, conferring both controlled stiffness and resilience which provides good impact strength and shock resistance in combination with high tensile strength and assured solidity.
