PWA 1222 is a Pratt & Whitney specification for 6Al-2Sn-4Zr-6Mo titanium. Also known as Ti-6Al-2Sn-4Zr-6Mo or simply 6-2-4-6 titanium, is a type of titanium alloy that is commonly used in the aerospace industry. It is a high-strength alloy that is known for its excellent corrosion resistance, fatigue resistance, and toughness. This alloy is used in intermediate compressor stages of turbine engines for disks and blades, seals, and for airframe parts.
Pratt & Whitney is a subsidiary of Raytheon Technologies. Pratt & Whitney’s aircraft engines are widely used in both civil aviation and military aviation.
When sourcing material for Pratt & Whitney projects, there is a call out for Laboratory at Controlled Source (LCS) requirements that Fighter Jet Metals works to ensure that this quality requirement is met. If your project calls out PWA 1222 make sure to request a quote with Fighter Jet Metals to ensure that quality requirements are met.
The high strength and corrosion resistance of 6Al-2Sn-4Zr-6Mo titanium make it a suitable material for use in structural components, such as airframes and fuselages. Its low density also helps to reduce the overall weight of the aircraft, which is important for improving fuel efficiency.
6Al-2Sn-4Zr-6Mo Round Bar diameters range from 0.125″ to 14.00″ diameter.
