Titanium Powders

Titanium powders in particular are lightweight, strong and corrosion resistant and used in a wide range of today’s most demanding markets. Continuous development of titanium and other alloy powders has enabled AMETEK to expand into demanding markets such as coating powders for orthopedic medical devices, powder metallurgy and injection molding applications. These powders are supplied to meet medical ASTM F1580 chemistry requirements and are also suitable for use in traditional powder metallurgy.

The Hydride-Dehydride (HDH) process is used primarily for Ti and Ti-6Al-4V powder production. It relies upon the brittle nature of corresponding metal hydrides. These metal hydrides are milled and screened to produce fine powders. After the powder is sized, interstitial hydrogen is subsequently removed using vacuum and heat to produce finished metallic powders. These powders are irregular and angular in morphology and can also be magnetically screened and acid washed to remove any ferro-magnetic contamination. 

The brittle hydrides are then crushed and classified to the desired particle size range. The crushing process produces a range of particle size distributions (PSD). Particle size distribution can be controlled via classification methods to meet upper and/or lower limits. Reading Alloys currently offers powders down to 325 mesh (45 microns) distribution.
