Aluminum Casting Alloy for Near Net Shaped Casting of Structural or Non-structural Components

Abstract

An aluminum casting alloy for near net shaped casting of structural or non-structural components containing, in % by mass, Zn: 4.5-7.5%, Mg: 0.7-2.0%, Fe: 0.8-2.0%, Si: <0.3%, Cu: <0.1%, V: ≤0.2%, Ti: ≤0.2%, B: ≤0.04%, balance Al and unavoidable impurities, the sum of the contents of the impurities being≤0.1%. Also, a method for the manufacture of a cast part which has a yield strength of 180 to 200 MPa, an ultimate tensile strength of 300 to 320 MPa and an elongation of 11 to 14% and a method for the manufacture of a cast part which has a yield strength of 210 to 400 MPa, an ultimate tensile strength of 340 to 450 MPa and an elongation of 2 to 11% utilizing the described alloy.
