Grade 9 titanium tube is a low alloying near-alpha titanium alloy. The alloy has good cold formability and welding performance. The room temperature strength is 20% to 50% higher than that of industrial pure titanium. It has good corrosion resistance in many media. performance. Therefore, Gr9 titanium alloy has become the most suitable material for making high-pressure-resistant light-weight conduits on aircraft due to its excellent comprehensive properties. At the same time, Grade 9 titanium alloy tubes are widely used in bicycle frames and titanium alloy T bar.

Why Grade 9 titanium alloy Ti-3Al/2.5V tube is suitable for making bicycle frames?

The material requirements of the bicycle frame are very simple, but the driving characteristics are particularly critical, which complicates the selection of materials in some aspects. There is no titanium alloy specially designed for bicycles. Only some materials have been improved for bicycles. Most people consider cost reduction, and the main problem faced by titanium components is rigidity rather than cost.

The selection of materials is usually based on a comprehensive consideration of various factors, such as strength, density, cold workability, hot workability, price, corrosion resistance, etc.

Ti-3Al/2.5V is the most commonly used titanium alloy for bicycles. Although it is developed for aircraft hydraulic systems, it meets the performance standards of the bicycle market due to formability, corrosion resistance, high specific strength, and good elongation. Compared with other titanium alloys, the biggest advantage of Ti-3Al-2.5V is its high yield strength and easy tube forming (cold workability). The disadvantage is its price and poor modulus-density ratio (compared with other titanium alloys). Ti-6Al/4V also has a certain attraction. Its elastic modulus and specific strength are higher than Ti-3Al/2.5V, but it is very difficult to process into a tube with a small diameter like a bicycle frame. Ti-15V/3Al/6Cr/4Mo/4Zr is also easy to shape, but its higher density and lower modulus offset its advantages in strength improvement.
