A superior combination of strength, elongation and cost compared to other aluminum alloys with similar properties for additive manufacturing
• New, innovative aluminum alloy: lightweight, high strength, elongation and corrosion resistance
• Single-step heat treatment without water quench
• Ideal for aviation, space, electronics and transportation industries
Krailling, Germany, October 18, 2023 – EOS, a leading supplier of responsible manufacturing solutions for industrial 3D printing, today announced the addition of its 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.
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.
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.
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. Also interesting 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 suite customers preferences, with the added bonus of corrosion resistance.
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.
