Abstract
A high performance die castable aluminum alloy is described, wherein the aluminum alloy is characterized as having a high yield strength and high conductivity compared to conventional aluminum alloys, and also a high flowability and low susceptibility to hot tearing when die cast. The aluminum alloy may contain 4-6 wt. % nickel, a yield strength of at least about 90 MPa, and an electrical conductivity of at least about 48% IACS.
