Production and Properties of Recycled Aluminium Alloy Powders via Inert Gas Atomisation

Year: 2025

Type: article

Abstract: Inert gas atomization is a suitable technique for producing highly spherical powders used in metal additive manufacturing and other powder metallurgy techniques. Research into environmental sustainability is leading to new considerations in metal powder quality, gas atomisation processes, and raw material selection. This work presents the properties and sustainability of some gas-atomised aluminium-based powders. This study compares the characteristics of final powders made from conventional or innovative aluminum-based alloys belonging to the 2.xxx and 4.xxx series, using secondary or scrap materials. The comparison is based on granulometry, morphology, microstructure, and chemical composition, including light elements such as O, N, H, C, and S.
