Nitinol Sheet

Nitinol sheet, also known as nickel titanium sheet, is primarily composed of 54.5-57 wt% nickel and 43 wt% titanium. In addition to flat nitinol sheets, we also offer a range of other forms including nitinol foil, nitinol ribbon, and nitinol strip, catering to various applications.

THT is a nitinol manufacturer and nitinol supplier in China. Besides raw nitinol material, we also provide customized solutions based on customer requirements, including precision laser cutting, electrical discharge machining (EDM), photochemical etching, stamping, punching, and deep drawing. Our nitinol sheet has shape memory alloy and super elastic two functions which could be used in different applications. Our nitinol sheet standard meets ASTM F2063, with good fatigue resistance, super elasticity, shape memory effect, corrosion resistance and other characteristics, it is suitable for medical, aviation, electronics, machinery and other fields and our nitinol sheet could be customized in different thickness, width and length accordingly.

Application-1

Biomedical applications: Our Nitinol sheets are widely used in biomedical applications such as orthopedic implants, catheters, and cardiovascular stents due to their excellent biocompatibility. The shape memory alloy function of Nitinol is fully utilized in these applications. For example, Nitinol plates can be made into a folded form and inserted into arteries or veins in the human body. When the body temperature rises above a specific transition temperature (Af temperature), the Nitinol material reverts to its original, pre-determined shape, which helps the stent or catheter to precisely position and expand in the body.

Application-2

Bridges and buildings: THT elastic nitinol plates are used to create crack-sensing elements. They can be embedded in concrete structures to monitor and sense the occurrence and dimensional changes of cracks in real time, providing a structural health monitoring and early warning system to ensure the long-term safety and stability of the building.

Electronics: THT Nitinol plates are used in a wide range of high-tech products such as thermoelectric actuators, miniature sensors and shape memory alloy connectors.

Shape Memory Alloy VS Superelastic

Shape Memory Nitinol Sheet: Through heat treatment, we set the deformation to occur at a specific temperature. When heated above the AF temperature, our nitinol plate will automatically return to its original unshaped state. According to the recovered shape characteristics, shape memory nitinol plates can be categorized into: single-pass shape memory, double-pass shape memory and full-pass shape memory.

Superelastic Nitinol Sheet: It does not rely on heat treatment, but is deformed by an external force. After the withdrawal of external forces, it can quickly return to its original shape, and its elasticity is 10 to 30 times that of ordinary metals.

Other About THT Nitinol Sheet Feature

1. High Damping
Our Nitinol sheets have excellent high damping properties, which can self-adjust the motion during phase change and effectively absorb and dissipate vibration and shock energy. This makes Nitinol sheets outstanding in the field of vibration and noise damping, and widely used in demanding industries such as automotive, aerospace, and electronic equipment. Through its unique shape memory properties, Nitinol plate can significantly reduce noise and mechanical shock under vibration and shock conditions, enhancing product life and comfort.

2.Excellent Corrosion Resistance
Our Nitinol sheets have corrosion resistance comparable to stainless steel, especially in harsh environments. A dense oxide film naturally forms on its surface, which is highly stable and resistant to oxidation and corrosion. Whether in the marine, chemical industry or other highly corrosive environments, Ni-Ti alloy plate provides durable corrosion protection, ensuring long-term stability and safety.

What is meaning about Af temperature?

Af full name is Austenite Finish Temperature. It is shape memory alloy which recovers its original shape at the lowest temperature .

What is meaning about As temperature?

As is is the temperature at which the alloy begins to transform into the austenitic phase.

What other nitinol product you provide besides nitinol sheet?

Besides nitinol sheet, we can also provide nitinol powder, nitinol rod, nitinol wire, nitinol tubing, nitinol crucible, nitinol nuts, nitinol bolts, nitinol springs ,nitinol parts and so on.
