Product Overview
Ti-5Mo-5V-8Cr-3Al titanium alloy, corresponding to the domestic grade TB2, is a near-β type titanium alloy. Ti-5Mo-5V-8Cr-3Al titanium alloy has many advantages such as excellent cold working forming performance, high creep aging strength and fracture toughness, large quenching depth, good corrosion resistance, good instantaneous performance at high temperature, and excellent welding performance. It is often used to manufacture solid rocket engine shells, sheet metal parts, pressure vessels, aircraft missile skins, star arrow connecting belts, etc., and is also used as a material for load-bearing structural parts of spacecraft cabins. It is suitable for manufacturing aerospace fasteners that work below 300°C, or aerospace fasteners that work for short periods of time below 500°C. At present, the commonly used standards in China are GB/T2965-2007 "Titanium and Titanium Alloy Bars" and GJB2219A-2015 "Specifications for Titanium and Titanium Alloy Rod and Wire for Fasteners".

Product features and application fields
Ti-5Mo-5V-8Cr-3Al titanium alloy rod has many advantages such as excellent cold working forming performance, high creep aging strength and fracture toughness, large quenching depth, good corrosion resistance, good instantaneous performance at high temperature, and excellent welding performance. Plate and strip are often used to manufacture solid rocket engine shells, sheet metal parts, pressure vessels, aircraft missile skins, star arrow connecting belts, etc., and are also used as materials for load-bearing structural parts of spacecraft cabins. The bar can be cold-headed out of various head bolts, which can be used in the state of solution treatment or solution aging. Ti-5Mo-5V-8Cr-3Al titanium alloy is suitable for manufacturing aerospace fasteners that work below 300°C, as well as aerospace fasteners that work short-term below 500°C. Our company has many years of production experience in Ti-5Mo-5V-8Cr-3Al titanium alloy bars, and has the ability to produce Φ2~230×Lmm bars in batches and stably in batches.
