Ti6242

Ti-6242 is a titanium alloy with the approximate composition of 6% aluminum, 2% tin, 4% zirconium, and 2% molybdenum by weight. It is a high-strength, alpha-beta titanium alloy known for its good combination of properties at elevated temperatures. The presence of aluminum and zirconium stabilizes the alpha phase, while molybdenum contributes to solid solution strengthening and improves creep resistance.

This alloy exhibits good tensile strength and fatigue resistance, making it suitable for applications where thermal stability is important. It can be heat-treated to achieve a wide range of mechanical properties. Ti-6242 is typically processed using standard titanium manufacturing techniques, including forging, rolling, and machining.

Due to its elevated temperature capabilities, Ti-6242 finds use in aerospace engine components, such as compressor blades and discs, as well as in airframes where high performance under thermal stress is required. Its corrosion resistance is also a notable characteristic, consistent with other titanium alloys. However, like many titanium alloys, it can be susceptible to hydrogen embrittlement under specific conditions.
