CT Puris SM-100 Titanium Powder

CarTech Puris SM-100 titanium powder is an ideal option for applications that require a corrosion-proof, wear-resistant solution, properties formerly considered to be mutually exclusive.

CarTech Puris SM-100 titanium powder is ultra-elastic, non-magnetic (low-mu certified) and 20 percent lighter than steel. Other attractive features include:

  • High hardness (>60 HRC)
  • Shape memory
  • High conductivity
  • High strength

NASA tested CarTech Puris SM-100 titanium powder in several environments against 440C stainless steel and other leading bearing and wear components, and identified the following three superlative performance properties:

  • Lower coefficient of friction
  • Higher strain tolerance with high resulting elasticity
  • Higher damage level threshold
