TC4 titanium alloy rod, also known as Ti-6Al-4V, is an α+β type titanium alloy containing 6% aluminum and 4% vanadium. It has high strength, low density, excellent corrosion resistance, good toughness and weldability. This titanium alloy is widely used in the aerospace field to manufacture aircraft parts and engine components; in the automotive industry, TC4 titanium alloy can significantly reduce the weight of parts, improve fuel efficiency and performance; in medical devices, due to its biocompatibility, it is often used to manufacture artificial joints. In addition, it is also used in some key components in the petrochemical, shipbuilding and power industries, such as gas turbine blades, etc.
