CP Grade 4 - AMS 4901


Commercially Pure or CP Titanium in unalloyed. Grade 4 is the strongest of the CP grades, with a minimum yield strength of 480 MPa (70ksi) and has the highest allowable oxygen and iron content of the grades. This material features excellent resistance to corrosion and corrosion fatigue as well as high strength.

Common Applications of CP Grade 4 Titanium

  • Airframe and aircraft engine components
  • Marine and chemical processing and desalinization plants
  • Corrosive waste disposal wells
  • Pulp and paper production
