High Strength-to-Weight Ratio: Titanium alloys have an excellent strength-to-weight ratio and are one of the strongest materials among metals. Compared with steel and aluminum, titanium alloys have a lower density, so the use of titanium alloys in the aerospace field can achieve lighter designs, reduce the weight of aircraft, and improve fuel efficiency and carrying capacity.

Good corrosion resistance: titanium alloy has good corrosion resistance, and has high corrosion resistance to most common corrosive media. This makes titanium alloys particularly suitable for components in the aerospace sector that face corrosive environments, such as spacecraft casings, engine components and fuel systems.

Excellent high temperature strength: titanium alloy has good strength and stability in high temperature environment. This allows titanium alloys to withstand high temperature stress and extreme temperature requirements in aerospace, such as the high temperature environment faced by engine components and spacecraft entering the atmosphere.

Good biocompatibility: Titanium alloy has good biocompatibility and excellent compatibility with human tissue. This has led to the widespread use of titanium alloys in medical applications such as medical devices and artificial joints. In the field of aerospace, this feature also helps to reduce the adverse effects on the human body of parts that come into contact with astronauts.

Good machinability: Although titanium alloy has certain processing difficulties, it has better machinability compared with other high-strength metals. Titanium alloys can be formed by various processing methods, such as forging, casting, machining, etc., to meet the manufacturing needs of complex parts.
