ATI Defense Unveils ATI 425®-MIL Alloy at Eurosatory 2010

PITTSBURGH--(BUSINESS WIRE)--Allegheny Technologies Incorporated (NYSE: ATI) unveiled its new, game-changing titanium alloy for defense applications at Eurosatory 2010 in Paris, France this week. ATI believes that ATI 425®-MIL Alloy titanium plate and sheet will be especially well-suited for defense applications, particularly for vehicle armor and structural and suspension components for land-based vehicles.

ATI 425®-MIL titanium has tensile strength comparable to 6-4 titanium, the most common titanium alloy, with the added benefit of higher ductility so that, unlike 6-4 titanium, ATI 425®-MIL Alloy can be cold worked into complex shapes. ATI 425®-MIL Alloy provides a new range of design solutions to Defense OEMs based on its enhanced performance characteristics, including strength and formability. This new titanium alloy system offers customers a new set of design solutions for improving manufacturability and reducing weight while maintaining survivability in a wide range of land, sea and air defense applications.

ATI 425®-MIL Alloy plate is hot-rolled and annealed at ATI’s 110-inch (2.8-meter) mill, located in Washington, PA. Available in thicknesses ranging from 0.188 to 4 inches (4.7 to 101.6 mm) it has been classified as class 4 armor plate by the MIL-DTL-46077G specification and has proven to exceed all ballistic requirements for all thickness ranges. ATI 425®-MIL Alloy has also proven to exceed AMS 6946 specification minimums.

ATI 425®-MIL Alloy is also available in sheet gauges, which are continuously cold-rolled and annealed in coil lengths of up to 2,500 feet to create products that offer a unique combination of strength and formability. This compares to 6-4 titanium which is pack rolled in lengths of up to 20 feet.

Several examples of the advanced formability and characteristics of ATI 425®-MIL Alloy titanium plate and sheet will be on display at the ATI Defense stand, H441, in Hall 6 during Eurosatory.
