What is Nitinol Wire?

Nitinol is a special nickel-titanium alloy known for its shape memory and superelastic properties. It can automatically recover its original shape after plastic deformation when heated to a specific temperature.

The Nitinol Wire ASTM F2063 features an expansion rate of over 20%, a fatigue life of up to 10⁷ cycles, and excellent corrosion resistance—surpassing that of the best medical stainless steels. These properties make it highly valuable in both engineering and medical applications as a superior functional material.

Advantages of Nitinol Wire ASTM F2063

1. Shape Memory Effect
   Nitinol wire can return to its original shape through reverse phase transformation during heating and cooling cycles. This thermal-induced transformation enables the well-known "shape memory" effect.

2. Exceptional Elasticity
   The wire can undergo strains far greater than conventional metals and still recover its shape upon unloading. Its elastic limit is much higher than ordinary materials, providing outstanding resilience.

3. Construction Applications
   Superelastic Nitinol wire maintains good elasticity even under temperature fluctuations. When used in architectural applications, it helps accommodate thermal expansion and contraction in structures.

4. Superior Shock Absorption
   With excellent damping capacity—up to 10 times that of steel—Nitinol wire effectively reduces vibration and structural movement caused by seismic or other dynamic forces.

Baoji City Changsheng Titanium Co.,Ltd is registered in 2006. Registered capital of 10 million yuan, the legal person is Zhao Wenhua. Before 2006, the factory is formed as forged workshop, no been registered. The year of 2006 was exist as a starting for Changsheng Titanium Co. The factory is located in today’s No.26 Baotai Road Weibin District, Baoji City,Shaanxi Province. The factory is major in forging ,continuing the previous processing mode, but the scales has expanded nearly 30 times, and was on the right track. In 2008, it passed ISO 9001 certification.
In 2010, Baoji City Changtai Metals Trading Co.,Ltd was registered, with capital of one million yuan. The legal person was Zhao Wenli. It was located in today’s No.26 Baotai Road Weibin District, Baoji City,Shaanxi Province.
