Alcoa EZCast-NHT A152 and A153 are proprietary, non-heat-treatable, high-pressure die casting (HPDC) aluminum alloys in which magnesium is the principal alloying element. These alloys develop 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. This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties. It also includes information on corrosion resistance. Filing Code: Al-469. Producer or source: Alcoa Corporation.
