Nitinol Wire

THT is a leading nitinol wire manufacturer and supplier in China. We provide nitinol wire with superelasticity and shape memory function, and can customize one-way and two-way memory functions according to customer needs. The Af temperature can meet the requirements of room temperature, low temperature and high temperature. Our niti wire has 10 to 30 times the ability to deform and recover to its original shape than ordinary metals. At the same time, the carbon and oxygen content in our nitinol wire is much lower than the latest ASTM F2063-2018 standard.

In addition, our nitinol wire has the following superior properties:

  1. Excellent thermal conductivity
  2. Expansion rate can reach more than 20%
  3. Fatigue life reaches 10 million times
  4. The damping characteristics are ten times that of ordinary springs

Whatever nitinol wire you need, THT can provide high-quality solutions to meet your special application needs.

THT Nitinol Wire

THT Nitinol wire is available in a variety of shapes including flat, square and round with bi-directional shape memory. At high temperatures, our Nitinol wire transforms to an austenitic phase and then forms martensite when cooled to low temperatures, changing shape in the process. When reheated to its transformation temperature, the Nitinol wire reverts to the austenitic phase, returning to its original shape.

How To Make Nitinol Wire

Our nitinol wire uses high-purity nickel and titanium as raw materials, and further removes impurities through vacuum arc melting (VAR) in a high vacuum environment, thereby improving the purity of the nitinol and enhancing its fatigue resistance. The smelted billet is forged, hot rolled and cold rolled to significantly improve the strength and toughness of the alloy.

Subsequently, heat treatment reduces internal stresses and improves ductility. According to the customer’s needs, the alloy wire will be stretched to the required diameter and subjected to double water polishing and surface graphite emulsion polishing to ensure that the product surface is smooth and rust-free.

At every step, we strictly conduct sampling analysis, including chemical composition analysis and mechanical performance testing, to ensure that the final product meets high standards.

Nitinol Wire Application

Application

Our NiTi alloy wires are widely used in a variety of fields under different temperatures and properties:

1.Super elasticity at room temperature:
Mainly used in mobile phone antennas, toy antennas, glasses frames, Bluetooth headsets, ear hooks, underwear flat wire, spring wire and golf club inserts, etc.

2.Low temperature super elasticity:
It is mainly used for fishing hooks, fishing rods, raft rods, needle blocks and other fishing gear products, providing high-quality tools for fishing enthusiasts.

3. Temperature control material:
Mainly used in electrical appliances, sanitary ware, kitchenware, medical equipment, mechanical parts, aviation, nuclear industry, hardware products, springs, standard parts, fasteners and precision parts and other fields.
In addition, our niti wire is widely used in the medical field. Because of its small size, flexibility and remarkable efficacy, it is often used in orthodontic wires, dental arch wires, intrauterine devices and other products. THT niti wires can also be embedded in concrete to monitor cracks in civil structures such as bridges and buildings and provide timely intervention. In the aviation field, nitinol alloy wire is used in key components such as aircraft pipe joints, spacecraft antennas and brakes.
