Description

Designed for Processing in Laser Powder Bed Fusion (PBF-LB), Electron Beam Powder Bed Fusion (PBF-EB) or Directed Energy Deposition (DED) Systems 


MetcoAdd™ 718 is a family of nickel-based superalloy powders with chemistry similar to AMS 5662 bar material. 


Room temperature static properties of PBF-LB processed and heat treated material coupons have been shown to be comparable to those of AMS 5662. 


For reference purposes Oerlikon has processed MetcoAdd 718C using fixed parameters and 40 μm layer thickness to provide data below. Additional testing has been performed by an extensive network of consortia and customer partners on a broader range of machine types. Properties may be optimized based on application specific requirements.
