ATI 425® Alloy Applications
Markets for ATI 425® Alloy include aerospace, defense, industrial, medical and recreation in applications where high-strength, lightweight materials are required. In addition, the corrosion resistance of ATI 425® Alloy to saltwater environments makes it a candidate for marine-related applications.
Aerospace Applications
AMS 6946 provides that ATI 425® Alloy titanium sheet, strip and plate can be used for aerospace components. With pending adoption of ATI 425® Alloy MMPDS design allowables, it will soon be available for commercial aviation. Its key advantages, a combination of high strength, high ductility, continuous sheet form and super plastic formability, should position
As continuous cold-rolled sheet coil, ATI 425® Alloy has the product length, finish quality and gauge tolerance to potentially down-gauge and reduce joints in applications such as wing sheet. Available in both mill standard and slit-to-width sheet, ATI 425® Alloy can also potentially deliver similar benefits in seat tracks and other applications. Its finish quality can reduce the need for coatings to save cost and weight.
For hydraulic tubing, ATI 425® Alloy in extruded preform shapes can provide higher strength to accommodate higher psi loads. The tensile strength and ductility of ATI 425® Alloy may offer new options in fastener design as well.
Defense Applications
The defense version of ATI 425® Alloy, ATI 425®-MIL, is recognized by ASTM and has been assigned titanium grade 38. It is a proven solution for ballistic armor plate, capable of meeting or exceeding MIL-DTL-46077G Class 4 requirements.
Defense Rotor Aircraft
ATI 425®-MIL Alloy’s light weight, ballistic performance and availability in continuous cold-rolled sheet make it a candidate for applications where ballistic protection is critical. It is also a suggested material for high-stress applications such as helicopter rotors, where it provides light weight, high fatigue strength and formability.
Ground Vehicles
ATI 425®-MIL Alloy’s combination of strength, light weight, formability, corrosion resistance and ballistic performance has made it useful for armor and structural components. In ground vehicle applications, these attributes have contributed to longer lifecycle performance and fuel efficiency.
Soldier Support and Protection
Light weight, formability and ballistic performance have made ATI 425®-MIL Alloy a useful choice in these systems to provide protection with less fatigue in the field.
Weapons Systems
In weapons systems, ATI 425®-MIL Alloy’s strength, light weight and formability help create titanium components that reduce weight and provide excellent ballistic performance.
Naval Systems
For naval applications, ATI 425®-MIL Alloy delivers corrosion resistance, light weight and strength in a formable titanium material that provides excellent ballistic performance. Benefits include long lifecycle performance and energy efficiency in powered systems.
Boiler/Pressure Vessel Applications
The ASME Board on Pressure Technology Codes and Standards, (BPTCS) has approved ATI 425®-MIL Alloy for use in Section VIII, Div. 1 construction up to 600°F (316°C). ATI 425®-MIL Alloy has been Board Approved for use in the ASME Boiler and PV Code to 650°F. This makes ATI 425®-MIL Alloy the highest temperature ASME-code-approved titanium alloy in the B&PV code.
