These specifications tables aluminum alloy provide detailed information of the mechanical properties for three different die-cast aluminum alloys, including tensile strength, shear strength and Brinell hardness. The physical properties table shows the same alloys, detailing melting point and the coefficient thermal expansion. The third table provides the ASTM Chemical Specifications of the aluminum alloys.
