EOS, a leading supplier of responsible manufacturing solutions for industrial 3D printing, introduced the new EOS Aluminum Al5X1, an aluminum alloy engineered specifically for additive manufacturing (AM), but at a more competitive cost than other aluminum alloys with similar strength and elongation properties.

EOS Aluminum Al5X1 delivers excellent performance and material properties with a combination of high strength and elongation, around 410 MPa UTS and 14% elongation.

EOS Aluminum Al5X1 for the EOS M 290 will be commercially available in November 2023, followed by commercial availability for the EOS M 400-4 in 2024.

“A combination of high strength and high elongation for an aluminum alloy is critical for manufacturers in industries like aerospace, but equally crucial is delivering the property combination at a reasonable cost,” said Dr. Ankit Saharan, Senior Manager of Metals Technology at EOS. “Also interesting—Saharan continued—is that since the material can be anodized, this makes it very attractive to OEMs in areas like consumer electronics who are seeking to produce different colored products to suit customers preferences, with the added bonus of corrosion resistance.”

Requiring only a single-step heat treatment with no HIP (Hot Isostatic Pressing), organizations manufacture parts faster and at a lower total cost. 3D printed applications using EOS Aluminum Al5X1 can also be electropolished and anodized (Type II and Type III) for both cosmetic (colored) and corrosion-resistant protective properties. There are no limits to potential color choices, which could be important to consumer-facing products.

EOS Aluminum Al5X1 was tested by multiple organizations including world-leading semiconductor, aerospace and defense companies. Early adopters have noted that the material’s exceptional performance combined with the competitive cost-per-part (CPP) has created a strong business case for production implementation.

Brian Neff, founder & CEO of Sintavia, LLC, a designer and additive manufacturer of mechanical systems for the aerospace and defense industry, added: “Since early 2023, we have been working to develop Al5X1 performance data and material allowables on behalf of our prime customers. Preliminary results are very promising, and we look forward to introducing Al5X1 across our thermodynamic product lines. Developing a higher-performing aluminum alloy is of critical importance not only to us but also to the industry as a whole.”

EOS Aluminum Al5X1 for the EOS M 290 will be commercially available in November 2023, followed by commercial availability for the EOS M 400-4 in 2024.

  1. There’s no cost comparison provided to existing materials. If the main value prop is lower cost, it’d be nice to know if that means a few percent less expensive or 90%, for instance. Thanks.

    1. That makes a lot of sense. In this case we are just reporting the news story but it will be interesting to find out. We do publish market studies and ebooks that provide more in depth-information when it is available
