Laser-Sintering Powders Target Aerospace Industry
Two powdered metals for the rapid manufacture of nickel alloy and aluminium alloy components by additive layer manufacturing have been introduced by EOS Electro Optical Systems . The company has specified the materials for use in its EOSINT M 270 laser-sintering systems. EOS nickel alloy IN718 is a nickel-based, heat-resistant super alloy, which corresponds to Inconel 718. It is a precipitation hardening, nickel chromium alloy characterised by good tensile, fatigue, creep and rupture strengths at temperatures up to 700C. It shows high corrosion resistance, is suitable for many high-temperature applications and possesses strong cryogenic properties. The material may be of particular interest to the aerospace industry due to its demanding requirements. EOS said that it has carried out extensive tests in collaboration with several pilot customers. It has developed process parameters that enable good part building and ensure that the relevant industrial standards for this material type can...
