Abstract
A method for making an article is disclosed. The method involves inputting a digital model of an article into an additive manufacturing apparatus comprising an energy source. The additive manufacturing apparatus applies energy from the energy source to successively applied incremental quantities of a powder to fuse the powder to form the article corresponding to the digital model. The powder includes an aluminum alloy having 2.00-9.00 wt. % cerium, 0.25-3.00 wt. % silicon, 0.25-0.75 wt. % magnesium, 0-0.75 wt. % iron, 0-0.05 wt. % other alloying elements, and the balance of aluminum, based on the total weight of the aluminum alloy.
