EOS NickelAlloy HX is a heat and corrosion resistant metal alloy powder intended for processing on EOSINT M 280 systems.

EOS NickelAlloy HX is a nickel-chromium-iron-molybdenum alloy in fine powder form. Its composition corresponds to UNS N06002. While the wrought and cast versions of the alloy generally are solution annealed, the laser sintered version has a high strength and good elongation already in the as-built condition. Solution annealing of the laser sintered material will homogenize the microstructure, relax internal stresses and increase the elongation, while slightly decreasing the strength.

This type of alloy is characterized by having high strength and oxidation resistance also at ele- vated temperatures, and is often used up to 1200 °C. Therefore its applications can be found in aerospace technology, gas turbine parts, etc.

Standard laser processing parameters results in full melting of the entire geometry, typically with 20 µm layer thickness. Parts built from EOS NickelAlloy HX can be heat treated and mate- rial properties can be varied within specified range. In both as-built and solution heat treated states the parts can be machined, spark-eroded, welded, micro shot-peened, polished, and coat- ed if required. Unexposed powder can be reused.
