HDH Titanium Powder
Hydride-dehydride (HDH) Process
This method uses hydrogen to make the titanium brittle enough to crush and perform initial sizing. Hydrogen is then removed under vacuum followed by final sizing to customer specifications. This process creates a final particle morphology described as blocky or angular.
