ELEKTRON ZRE1 is a magnesium-base casting alloy which combines excellent creep resistance up to about 500 F with good room temperature properties. It is completely free from microporosity and very suitable for applications requiring pressure tightness. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as creep and fatigue. It also includes information on corrosion resistance as well as casting, heat treating, machining, joining, and surface treatment. Filing Code: Mg-6. Producer or source: Aluminum Laboratories Ltd.
