Rationale: To take full advantage of the potential of additive manufacturing in the aerospace industry, higher strength aluminum alloys are needed.This alloy uses additives to prevent solidification cracking, which is common in aluminum alloy AM, and achieves properties that surpass those of cast aluminum C355. Parts made from this alloy cannot be produced by any process other than LPBF, such as casting or forging.The specification provides guidelines for controlling the production, processing, and evaluation of components for aerospace applications.
