Abstract
There is claimed an Al—Ni—Mn based alloy for die casting, squeeze casting, permanent mold casting, sand casting and/or semi-solid metal forming. The composition of this alloy includes, by weight percent: about 0.5-6% Ni, about 1-3% Mn, less than about 1% Fe, less than about 1% Si, less than about 0.3% Ti, and less than about 0.06% B, the balance Al, incidental elements and impurities. It is suitable for aerospace and automotive cast parts.

An aluminum casting alloy composition that includes:
- about 0.5-6 wt. % Ni, about 1-3 wt. % Mn, less than about 1 wt. % Fe, less than about 1 wt. % Si, less than about 0.3 wt. % Ti, and less than about 0.06 wt. % B, with incidental elements and impurities.
An aerospace structural component cast from an alloy composition that includes:
- about 0.5-6 wt. % Ni, about 1-3 wt. % Mn, less than about 1 wt. % Fe, less than about 1 wt. % Si, less than about 0.3 wt. % Ti, and less than about 0.06 wt. % B, the balance aluminum, incidental elements and impurities.
An automotive structural component cast from an alloy composition that includes:
- about 0.5-6 wt. % Ni, about 1-3 wt. % Mn, less than about 0.1 wt. % Fe, less than about 0.1 wt. % Si, less than about 0.3 wt. % Ti, and less than about 0.06 wt. % B, the balance aluminum, incidental elements and impurities.
