CP Titanium • UNS R50250, R50400

CP Titanium is selected for its favorable strength to weight ratio and excellent corrosion resistance. Two levels of purity permit a choice of finish strength.

The alloy can be formed from the annealed temper. Severe forming may be aided by an intermediate stress relief at 1000°F. Stress relieving may be appropriate after severe cold forming to remove residual stresses. Welding should be performed with inert gas shielded arc or spot welding. Welding with active gases, coatings, or fluxes must be avoided to prevent embrittlement.

Available Sizes:

CP Titanium is available from Hamilton Precision Metals as strip product from 0.0005” to 0.025” (0.0127 mm to 0.635 mm) and widths up to 12.0” (304.8 mm). A foil product is available as thin as 0.000085” (0.002159 mm) and widths of 4.0” (101.6 mm) maximum. The material conforms to ASTM F67, ASTM B265, AMS 4902 and UNS R50250,R50400.
