The Application of Titanium Springs

1) Aerospace: Reliable Support for Flying Through the Skies
In the aerospace field, titanium alloy springs play a crucial role. The landing gear springs are made of Ti-6Al-4V(Ti Grade 5) material and undergo heat forming and aging treatment, with a fatigue life of over 10⁷ times, capable of withstanding the huge impact forces and frequent load changes during aircraft takeoff and landing. The engine valve springs are made of Ti-3Al-2.5V(Ti Grade 9) material and are processed using cold drawn wire and shot peening technology, with a temperature resistance of 450℃, ensuring the stable operation of the engine in high-temperature environments.

(II) Medical Devices: The Gentle Power That Protects Life
In the field of medical devices, the requirements for the biocompatibility and performance stability of materials are extremely high. The vascular stent springs are made from Ti Grade 1 cold-drawn wire, with diameters ranging from 0.1 to 0.3 mm. They are electrochemically polished to Ra < 0.1 μm, resulting in a smooth surface that does not cause damage to the blood vessels. Their excellent elasticity and biocompatibility can provide stable support for the blood vessels and help patients recover their health.

(III) Automotive Industry: The Lightweight Choice for Enhancing Performance
According to Titanium House, in recent years, the application of titanium alloy springs in the automotive industry has witnessed an explosive growth. Racing suspension springs use Ti-6Al-4V material, which reduces the weight by 40% compared to steel springs, and also allows for adjustable stiffness. The reduced weight can lower the energy consumption of the racing car, enhance its acceleration performance and handling. The adjustable stiffness can be optimized according to different track conditions and driving requirements, providing a better driving experience for the racing driver.
