EOS expands its metal powder range with four new alloys
EOS GmbH, headquartered in Krailling, Germany, has added four new metals to its Additive Manufacturing materials portfolio: EOS FeNi36, EOS NickelAlloy C22, EOS Steel 42CrMo4, and EOS StainlessSteel 316L – 4404. Each material is optimised for the company’s Laser Beam Powder Bed Fusion (PBF-LB) AM machines.
The new metal powders will further expand the company’s ability to address specialised AM requirements across industries such as aerospace, energy, chemical, automotive, and marine.
“With these additions, we continue to expand our materials portfolio to meet the most demanding industry requirements,” stated Hanna Pirkkalainen, head of product, EOS Oy. “Whether it is the unmatched thermal stability of EOS FeNi36, the corrosion resistance of NickelAlloy C22, or the accessibility of widely used steels like 42CrMo4 and 316L-4404, we are enabling our customers to innovate faster, address supply chain challenges, and bring Additive Manufacturing into new applications. Our team is excited to discuss our entire metal materials portfolio at Formnext.”
EOS FeNi36
Designed for aerospace, space, defence, and energy applications, EOS’s new iron-nickel alloy is aimed at applications where precision and stability under fluctuating temperatures are critical. With a low coefficient of thermal expansion (<2 ppm/K between 30–150°C), EOS FeNi36 is said to provide up to 10x lower thermal expansion than alloys such as 316L and MS1.
Typical applications include optical housings, mirror mounts, cryogenic instrument components, optical benches, precision metrology inserts, and small composite tooling inserts.
EOS FeNi36 is compatible with the EOS M 290 AM machine and is commercially available now.
EOS NickelAlloy C22
EOS NickelAlloy C22 is said to offer good corrosion resistance, high strength and toughness to applications where contact with biological and chemical media is unavoidable. The alloy is designed for use in chemical processing and food processing, providing manufacturers with a solution for components exposed to highly aggressive environments.
With the new alloy, EOS is extending its portfolio into new fields, enabling broader adoption of AM in chemical industries. The material is initially compatible with EOS M 290 machines.
EOS Steel 42CrMo4
Steel 42CrMo4 is widely used in the automotive industry. This low-alloyed steel is known for its high toughness and strength, making it ideal for components such as gears, crankshafts, and connecting rods.
The use of this cost-effective, industry-standard steel in Additive Manufacturing will enable lightweight design, faster development cycles, and greater supply chain flexibility for engineers. EOS Steel 42CrMo4 is compatible with EOS M 290 machines and is commercially available now.
EOS StainlessSteel 316L-4404
EOS StainlessSteel 316L-4404 is a European industry-standard stainless steel variant that combines high ductility, toughness, strength, and corrosion resistance. Tailored for industries such as chemical processing, food production, water handling, and marine, the alloy delivers good performance at a lower cost.
The new chemistry variant is more industrial-grade than standard EOS 316L while maintaining compatibility with existing StainlessSteel 316L parameter sets. The material is compatible with a wide range of systems, including EOS M 290, EOS M 400, EOS M 400-4, and EOS M 300-4.
