Arconic Unveils Advanced Titanium Alloy for Higher Temperature Aerospace Applications

As next generation aero engines run hotter, ARCONIC-THOR™ delivers a lighter, more cost-effective titanium alternative to incumbent nickel-based superalloys

Arconic announced the commercial availability of an advanced titanium alloy— called ARCONIC-THOR— that is designed for higher temperature applications in next generation aero engines and adjacent structures. Patented ARCONIC-THOR is nearly 50 percent lighter than incumbent nickel-based superalloys, driving cost savings and fuel efficiency for customers and helping Arconic capture growing demand for advanced aero engine and airframe materials.
 
“ARCONIC-THOR is a breakthrough aerospace material that goes where conventional titanium alloys cannot,” said Jeremy Halford, President, Arconic Engineered Structures. “Next generation fuel-efficient aero engines are running hotter, presenting a materials challenge for the exhaust systems and adjacent structures. Drawing on our materials science expertise, our engineers formulated ARCONIC-THOR—a powerful titanium solution that can take the heat and unlock significant weight and cost savings for our customers.”
 
Within Arconic’s patented alloy ranges, ARCONIC-THOR’s specific proprietary formulation demonstrates three times improved oxidation resistance compared to existing high temperature titanium alloys. This improved oxidation resistance protects against deterioration at elevated temperatures and enables ARCONIC-THOR to operate at service temperatures higher than any other conventional titanium alloy available on the market.
 
Arconic already has completed successful development projects of ARCONIC-THOR with customers. These include a U.S. Air Force Research Laboratory-funded project with aircraft manufacturer Boeing and aircraft engine manufacturer Honeywell in which we produced full- scale components from.
 
ARCONIC-THOR sheet. The joint Materials Affordability Initiative (MAI) project validated ARCONIC-THOR as a production-ready, superior oxidation resistant titanium alloy at temperatures as much as 200°F above previously available high temperature titanium alloy products with acceptable oxidation resistance. The project further concluded that ARCONIC-THOR significantly reduced weight and improved component performance.
 
The Society of Automotive Engineers - Aerospace Material Specification Titanium and Refractory Metals Committee (SAE-AMS) recently approved the standard Aerospace Material Specification (AMS) 6953 for ARCONIC-THOR sheet.
 
ARCONIC-THOR can be produced as sheet, plate, foil, billet, rolled rings, forgings and extrusions. It is formable (cold, hot, superplastic), heat treatable, forgeable and weldable.
