Titanium powders for medical industry implant applications

Titanium Powders

Titanium powders 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 Reading Alloys 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.

Titanium Alloys
Reading Alloys offers the following titanium and titanium Alloy materials via the
hydride-dehydride (HDH) process:

  • Commercially Pure (CP) Titanium Powders
  • Magnesium Reduced Titanium Sponge Powders
  • Sodium Reduced Titanium Sponge Powders
  • Titanium 6Al-4V Powders

Size range and characteristics

  • Typical particle size distributions (PSD) range from 45 microns (325 mesh) to 500 microns (35 mesh)
  • Blocky and angular, spongey, or equiaxed morphology

Applications
Coatings on titanium alloy medical implants to promote osseointegration, net shape, thin film (sputtering target) and feedstock.

Advantages
HDH Titanium powders offer a wide range of PSD and chemistry grades and provide an affordable titanium powder alternative. HDH Titanium powders are free flowing with careful selection of PSD, raw material feedstock, and powder morphology. These powders have been successfully used  in a wide range of traditional PM applications to make cost effective net shape and near net shape products.

Hydride-Dehydride (HDH) process
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 have b
locky and angular, spongey, or equiaxed morphology and can also be magnetically screened and acid washed to remove any ferromagnetic 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.

Medical grade titanium powders
Our medical grade titanium coating powders offer major advantages in orthopedic implant applications:

  • Blocky and angular, spongey, or equiaxed morphology to promote osseointegration
  • Custom particle sizes
  • Conformance to ASTM F67 and F1580
  • Excellent biocompatibility
  • Increased wear life

Our manufacturing process produces high purity titanium powders that enable critical orthopedic implants to join with bones and tissue to create excellent adhesion that speeds recovery time.
