Aluminium Materials Technologies (AMT), Worcester, UK, has secured aerospace recognition with the publication of AMS7033 standard for its high-strength, high-temperature A20X aluminium powder for Additive Manufacturing. The AMS7033 specification covers the aluminium alloy in the form of pre-alloyed powder, enabling the AM of aerospace components from A20X.

AMT explained to Metal AM magazine, that it became an Eckart/Altana company in September 2020, and with Eckart being one of the top three aluminium atomisers in the world the combined expertise has boosted the development of the A20X powder.

The atomised alloy is compatible with the majority of leading AM machines and is actively being used in environments that require A20X’s high temperature and high strength properties. Components that have been additively manufactured demonstrate excellent fatigue properties and resistance to stress corrosion cracking.

Based on the patented MMPDS aerospace-approved aluminium alloy A205, the A20X (2A05.50) atomised alloy powder has the same composition as its parent. A20X is now in flying component production with aerospace OEMs, T1 suppliers, AM bureaus and numerous universities.

The publishing of AMS7033 is reported to be the culmination of extensive and in-depth discussions with Additive Manufacturing experts, including members from leading aerospace companies, who ensure the specification‘s veracity. The company believes that the granting of AMS7033 further illustrates that A20X powder is a leading aluminium powder in the aerospace market.
