WHITE LIGHT-MF is a wrought magnesium-base alloy that does not respond to age-hardening heat treatment for increased hardness and strength. It is a general purpose extrusion alloy for applications where medium strength and economy are prime factors. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: Mg-30. Producer or source: Whitelight Magnesium Division.
