EOS expands metal powders portfolio with NickelAlloy HX

Additive manufacturing system provider EOS has added NickelAlloy HX to its metal materials portfolio. The heat and corrosion-resistant nickel-chrome-iron-molybdenum alloy has high strength and resistance to oxidisation, even at temperatures up to 1,200ºC.

EOS NickelAlloy HX has been optimised for use in the EOSint M 280 metal system and will usually processed in 20 µm layer thickness. Typical application areas include aerospace, heating elements in conveyor ovens, and industrial blast furnaces. EOS quotes Andreas Graichen, product developer (Gas Turbines) at Siemens Energy as saying: "We use the EOS additive manufacturing process for constructing prototypes, rapid manufacturing and rapid repair. EOS NickelAlloy HX's properties make it ideally suited to repair, as it is able to withstand the high temperatures to which gas turbines are constantly exposed. "For gas turbine burner repair, for example, instead of cutting away and discarding a large part of the burner head, we leave the structure intact, remove the top 20 mm or so, and then simply print a new combustion head."
