EOS rolls-out new high-strength, lightweight Al2139 aluminium alloy

The pioneers and innovators for integrated solutions in additive manufacturing EOS GmbH, has announced the addition of EOS Aluminium Al2139 AM, a new material distinctively developed for Additive Manufacturing. The alloy is set forth to offer high performance in elevated temperatures up to 200°C, superior corrosion resistance and is the highest-strength AM aluminium alloy obtainable from EOS.

Al2139 AM performs a yield and tensile strength of around 500 MPa in its heat treatment state. However, due to a single-step heat treatment procedure, companies can save up to 88% in active heat treatment time, this implicates parts that can be manufactured faster. The components manufactured using EOS Aluminium Al2139 AM can also be electropolished and anodised.

The conjunction of lightweight and strength quality of EOS Aluminium Al2139 AM are observed to make it suitable for a range of high-performance and demanding applications such as aviation, transportation, racing and the space industries, while also offering flexibility and enhanced material and production cost management to the contract manufacturing sector.

Sascha Rudolph, Senior VP of EOS Metal Materials said: “At EOS, we are constantly striving to improve the performance of our customer’s manufactured parts, whilst reducing the amount of material needed and streamlining production processes. EOS Aluminium Al2139 AM is a culmination of those efforts to put new materials innovations in the hands of manufacturers.”

The EOS Aluminium Al2139 AM material and process parameters for the EOS M 290 has although planned to float in Q1 2022, with process parameters for other EOS Laser Beam Powder Bed Fusion (PBF-LB) machines released soon after.
