Advanced Titanium Alloy Is Designed for Higher Temperature Aerospace Applications
NEW YORK–As next generation aero engines run hotter, Arconic is making available an advanced titanium alloy that is designed for higher temperature applications in next generation aero engines and adjacent structures. The company's patented ARCONIC-THORTM is reported to be 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, in a release from the company. "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 is said to demonstrate three times improved oxidation resistance compared to existing high temperature titanium alloys. The improved oxidation resistance protects against deterioration at elevated temperatures and enables the alloy to operate at service temperatures higher than any other conventional titanium alloy available on the market, the company said.
Arconic (www.arconic.com) completed a U.S. Air Force Research Laboratory-funded project with aircraft manufacturer Boeing and aircraft engine manufacturer Honeywell, in which Arconic 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 the alloy significantly reduced weight and improved component performance.
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. 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, the company said.
