EOS Expands Metal Material Offerings

EOS has made available two new metal additive manufacturing (AM) materials: EOS NickelAlloy IN718 API and EOS Nickel NiCP—both beneficial for EOS Laser Powder Bed Fusion (LBPF) 3D printing technology, the company notes.

EOS NickelAlloy IN718 API is made for high-performance oil and gas applications with API 6ACRA standard requirements. This nickel-based material combines high-impact toughness at low temperatures and corrosion resistance for high-stress oil and gas applications. With a tensile strength of 878 MPa and 27% elongation, when combined with a specific heat treatment, this material meets requirements for API 6ACRA standardization, for oil and gas manufacturers to use AM for downhole, injection and fixture, and for fastener applications.

An inflow control technology organization provided an early test case for EOS NickelAlloy IN718 API, producing a flow module component meeting API standardization and high-strength performance while being subjected to the corrosive environment of oil and gas equipment.

EOS Nickel NiCP is made for semiconductor and chemical applications requiring Nickel purity, corrosion resistance and ductility. This material provides a tensile strength of 400 MPa and 49% elongation, making it useful for applications like gas injectors and corrosion-resistant components within semiconductor capital equipment.

Parts can now be manufactured entirely with EOS Nickel NiCP, eliminating the need for plating and extending the life of the consumable.

“By additively manufacturing these parts, manufacturers can maximize machine uptime and availability, which in turn increases overall throughput of the wafer fabrication process and benefits the end user’s revenue,” says Sophia Heyl, EOS product specialist. “Eliminating the electroplating process that generates hazardous waste offers a cleaner, more sustainable manufacturing process for the future.”

“EOS Nickel NiCP has already been successfully deployed in production settings, demonstrating its reliability and performance,” says Dr. Ankit Saharan, EOS director of metals technology. “By making it more broadly available, we continue to strengthen our engagement with the semiconductor industry and our dedication to advancing their applications through innovative materials and processes.”

EOS NickelAlloy IN718 API is available for all metal EOS systems with standard EOS IN718 parameter processes. EOS Nickel NiCP is now commercially available for EOS M 290 and EOS M 400-4 systems.
