Description

Designed for Processing in Laser Powder Bed Fusion (PBF-LB) systems.


MetcoAdd™ H188-A is a cobalt-based powder product with chemistry similar to AMS 5772 bar and AMS 5608 Sheet or Plate material. 


Room temperature static properties of PBF-LB processed and heat treated material coupons have been shown to be comparable to those of AMS 5608. 


For reference purposes Oerlikon has processed MetcoAdd H188-A using 20 μm layer thickness to provide data below. Properties such as horizontal elongation may be optimized based on application specific requirements if desired.
