Product Overview
Ti-6Al-2Sn-4Zr-2Mo wire is an alpha-beta titanium alloy wire designed for elevated-temperature aerospace service. It provides strong high-temperature strength retention and good stability, making it a common choice for gas turbine and high-heat structural components. With relatively low beta content, it is considered to have good weldability when processed under strict cleanliness and inert gas shielding conditions.

Notes and Precautions
- For welding use, maintain ultra-clean conditions and use pure argon shielding; trailing and backside shielding may be required to prevent contamination.
- Mechanical properties vary by diameter and heat treatment condition; specify required condition and property targets at purchase.
- Avoid surface contamination during handling and storage; titanium is sensitive to interstitial pickup at elevated temperatures.
