The Rene 65 Alloy is ATI's latest nickel-based 'superalloy' developed in collaboration with GE Aviation.

The agreement covers Rene 65 Alloy disc-quality mill products sold to GE Aviation and its suppliers by ATI Allvac, an operating unit of Allegheny Technologies.

Rich Harshman, Chairman, President, and CEO of ATI, says: “This cooperative development effort between ATI and GE Aviation to create a cost-effective disc-quality product for use in jet engines operating at increasingly higher temperatures began just over four years ago. GE and its supply chain partners are in the process of taking advantage of the cost benefits and capabilities of Rene 65 Alloy by implementing the alloy in both legacy and next-generation jet engines.

“The short time involved in the development of Rene 65 Alloy is unprecedented and required a tremendous engineering effort by GE and ATI. This process illustrates the value that our integrated aerospace supply chain brings to new product development.”

The Rene 65 Alloy billet is produced at ATI's Titanium and Superalloy Forging Facility (TSAF), which houses one of the largest and most powerful open-die forge presses in the industry.

The Rene 65 Alloy billet is forged using both isothermal forging and hot die forging into several jet engine components.
