PWA 1222 - 6Al-2Sn-4Zr-6Mo Titanium Alloy for Aerospace Applications
PWA 1222 specification describes the Pratt & Whitney standard for the Ti-6246 alloy (6Al-2Sn-4Zr-6Mo). The Ti-6246 alloy is a high-performance titanium alloy that is highly valued in the aerospace industry for its high performance and reliability in high-temperature environments.
The alloy specified in PWA 1222 belongs to the alpha-beta titanium alloy family, which provides a strong balance between strength, ductility, and fracture toughness. Compared with conventional aerospace titanium alloys, such as Ti-6Al-4V, the 6Al-2Sn-4Zr-6Mo alloy offers significantly higher strength in large cross-sections while maintaining excellent structural stability under heavy loads.
PRATT & WHITNEY PWA 1222
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.
