ABSTRACT:
An aluminum-based material and method of manufacturing products from the aluminum-based material formed by a solid solution of zinc, magnesium and copper in aluminum with dispersed phase particles of aluminum, zinc, magnesium and copper essentially evenly distributed in the solution and particles of nickel aluminide being essentially evenly distributed in the matrix of the aluminum-based material that contains particles, essentially evenly distributed in the matrix, of at least one of the aluminides group such as chromium aluminide and zirconium aluminide, with a total content of 0.1–0.5% of the volume with the maximum amount of nickel aluminide particles being 3 μm and the proportion between the maximum and minimum amount of nickel aluminide particles of no more than 2 and with the maximum amount of chromium aluminide and zirconium aluminide particles is 0.05 μm, resulting in the aluminum-based material having a microhardness of no less than 170 HV, a tensile strength of no less than 530 MPa and elongation of no less than 2%.
