3D printer manufacturer EOS announced the launch of new EOS Aluminum Al5X1, an aluminum alloy designed specifically for additive manufacturing, but at a more competitive cost than other aluminum alloys with similar strength and elongation properties.
Specifically designed for the additive manufacturing process, this material promises similar strength and elongation properties to comparable aluminum alloys, but at a more competitive cost. With a strength of around 410 MPa and an elongation of 14%, EOS Aluminum Al5X1 clearly stands out.
Another advantage is that the material requires only a single heat treatment and does not need HIP (hot isostatic pressing). This enables faster and more cost-effective production of components. It can also be electropolished and both Type II and Type III anodized, providing both cosmetic (color) and corrosion protection properties. This opens up unlimited possibilities for color designs, which are especially important for consumer products.
Leading global companies in the semiconductor, aerospace and defense industries have already tested EOS Aluminum Al5X1. Early adopters are impressed by the exceptional performance and attractive price/performance ratio.
“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”, said Brian Neff, founder & CEO of Sintavia, LLC, a designer and additive manufacturer of mechanical systems for the aerospace and defense industry.
“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”, comments Dr. Ankit Saharan, senior manager of metals technology at EOS.
