EOS Aluminum Al2139 AM – new high-strength lightweight alloy with outstanding performance at elevated temperatures

With EOSHigh-strength aluminum alloy for 3D printing, companies can significantly reduce the weight of the items while a fast one-step heat treatment process ensures a more cost-effective production.

EOS, a leading provider of responsible manufacturing solutions via industrial 3D printing technology, is now introducing a new material, EOS Aluminum Al2139 AM.

Developed specifically for additive manufacturing (AM), the alloy offers outstanding performance at elevated temperatures up to 200 ºC. It is the one of EOS ‘AM aluminum alloys that has the highest strength and surpasses a number of similar alloys currently available on the market. EOS Aluminum Al2139 AM, with increased strength properties, gives customers good opportunities to significantly reduce the weight of manufactured items without compromising on strength.

In heat-treated state, Al2139 AM achieves a yield and tensile strength of about 500 MPa (megapascals), the highest strength of AM aluminum alloy. The material also has high strength at elevated temperatures up to 200 ° C and good corrosion resistance. Thanks to the metal’s fast and simple one-step heat treatment process, companies can save up to 88 percent time with active heat treatment – ensuring faster item production. Components made using EOS Aluminum Al2139 AM can also be electropolished and anodized.

Outstanding performance for demanding applications

The combination of low weight and high strength makes the EOS Aluminum Al2139 AM suitable for a range of high-performance and demanding applications such as aviation, transportation, racing and the aerospace industry. At the same time, the contract manufacturing sector is offered increased flexibility and improved cost management of production and materials. The EOS Aluminum Al2139 AM material as well as the process intended for the EOS M 290 are scheduled for release in Q1 / 2022, where EOS DMLS® systems will also be available.

Sascha Rudolph, Senior Vice President of EOS Metal Materials, said: “At EOS, we constantly strive to improve the performance of the items our customers manufacture, while reducing material consumption and streamlining production processes. EOS Aluminum Al2139 AM is the culmination of our efforts to offer manufacturers new material innovations. ”
