MIL-T-9047 – Titanium Bars & Forgings Specification
MIL-T-9047 ( AMS-T-9047 ) is a specification issued by the US military that covers bars of rolled or forged titanium, forgings, and reforging stock that are to be used in aircraft-quality aerospace work. It was first issued in 1955 by the US Department of Defense to standardize titanium alloys in military aircraft and aerospace work.
Since 1955, The Department of Defense has referred to Titanium Bars and Forgings as AMS-T-9047 / MIL-T-9047. This specification tends to cause a lot of confusion for Tier 1 Aerospace Manufacturers and OEMs because it covers 20 different types of titanium, and several conditions within some of the alloys. The MIL-T-9047 specification was cancelled in 1999 to move over to the widely used AMS specifications.
What is 5Al-2.5Sn Titanium ?
5Al-2.5Sn is an alloy made up of 5% aluminum and 2.5% tin. It is a high-strength, corrosion-resistant alloy that is commonly used in the aerospace and defense industries. Grade 6 Ti-5Al-2.5Sn alloy has high service temperature of 480°C (896°F), medium strength, and excellent weldability and fabricability. This alloy has good oxidation resistance and microstructure stability; however it is not heat-treatable.
Applications of MIL-T-9047 / AMS-T-9047 Titanium
Titanium materials referenced under MIL-T-9047 / AMS-T-9047 have historically been used in a variety of aerospace and military structural applications, including:
- Aircraft Structural Components : bars and forgings used in load-bearing aerospace structures
- Gas Turbine Engine Hardware : forged titanium components for aerospace propulsion systems
- Military Aerospace Systems : structural titanium parts used in defense platforms
