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.

L-605™ is a nonmagnetic cobalt-based chromium-tungstennickel alloy that has excellent corrosion and oxidation resistance, and high strength at both room and elevated temperatures. Through work hardening, high strength levels can be obtained. L-605™ has a minimal heat treatment response, but can be used in the cold worked and aged condition. Applications include medical implant devices, springs, valves, and engine components for the aerospace industry. As a result of its high tungsten content, L-605TM is radiopaque, which is beneficial for implant medical devices, such as stents. Because of the alloy’s high work hardening rate, only minimal reductions can be taken before solution annealing will be required. L-605TM is very resistant to oxidation and scaling at elevated temperatures, and is nonmagnetic in all conditions. L-605™ is produced by vacuum induction melting followed by electroslag remelting (VIM-ESR), and as such, has a low nonmetallic inclusion level.

SS 305 is an austenitic Chromium-Nickel stainless steel with excellent corrosion resistance, and is suitable for very severe cold forming operations. A high nickel content reduces the work hardening rate so that it can be formed into electronic components and remain non-magnetic. The alloy is readily formable and work hardens slowly.It has good resistance to nitric and sulfuric acid solutions although it will not resist halogen acids. The alloy can be satisfactorily welded, brazed, and soldered. Available Sizes: SS 305 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) in widths up to 12.0” (304.8 mm). It is also available in foil as thin as 0.000200” (0.00508 mm) in widths of 4.0” (101.6 mm) maximum. The material conforms to ASTM A240, QQS-766, and UNS S30500.
