Titanium Alloy

ATI 425® titanium is an innovative high strength alloy that has strength comparable to Ti-6-4, yet has the advantage that it can be cold worked. Originally developed for armor plate for ballistic protection, it was observed during processing to have exceptional hot workability. This observation led to additional testing that eventually demonstrated the alloy's versatility. ATI 425® titanium is produced by ATI Wah Chang and ATI Allegheny Ludlum in a variety of forms, including sheet, coil, strip, Precision Rolled Strip® product, plate, seamless tube and pipe as well as cast and engineering products. ATI 425® titanium is an alpha-beta alloy that utilizes iron in place of some higher-cost vanadium as a beta stabilizer. Among its advantages is that even though it is classified as a high-strength alloy, it can be cold worked quite easily, compared with Ti-6-4 which is unworkable at cold temperatures. Cold rolled — annealed ATI 425® titanium sheet has been bent to radii 2.5T at 105°
