The titanium alloy caliper pin is made of high-strength, lightweight and corrosion-resistant titanium alloy material, while ordinary steel parts usually use stainless steel, carbon steel and other materials. Due to the significantly lower density of titanium alloy compared to steel materials (the density of titanium alloy is approximately 4.51g/cm³, while the density of ordinary steel is approximately 8g/cm³), the titanium alloy caliper pin is lighter than the steel pin in the same volume. This makes titanium alloy have a clear advantage in applications that require weight reduction, especially in aerospace and high-performance automotive fields.

Although titanium alloys have a relatively low density, their strength is extremely high. Some high-strength titanium alloys can have tensile strengths of over 1200 MPa, which is much higher than the 400-800 MPa of ordinary steel. This means that titanium alloy caliper pins can provide higher strength and stiffness while maintaining a relatively light weight.

Titanium alloys possess extremely strong corrosion resistance and perform exceptionally well in various environments such as air, seawater, steam, and acids and alkalis, outperforming most steel grades. This characteristic enables titanium alloy caliper pins to have a longer service life in harsh conditions. Titanium alloy caliper pins are mainly used to fix and connect the caliper components in the braking system, ensuring their stability during use.

Titanium alloy materials have an extremely high strength-to-weight ratio, enabling the caliper pins to maintain strength while significantly reducing weight. This is highly beneficial for enhancing the performance and fuel efficiency of the vehicle. Titanium alloy exhibits excellent corrosion resistance and can be used for long periods in harsh environments without rusting or deteriorating. This helps to extend the service life of the caliper pins.
