Alcoa 560 is a proprietary, non-heat-treatable, aluminum-magnesium-manganese alloy developed by Alcoa in the late 1990s for high pressure die cast structural components. This alloy develops the required strength and toughness in the as-cast condition, thus eliminating or minimizing numerous production problems, such as distortion, blistering, property variations, and heat treatment logistics. The application of this alloy is limited to simple-shaped components due to its high hot cracking tendency. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as casting and joining. Filing Code: Al-478. Producer or source: Alcoa Corporation.
