NiTi Alloy Plate

Nickel-titanium alloy plate is a plate made of two alloy elements, mainly nickel and titanium, through several processes such as smelting, rolling, and heat treatment. It has super memory performance, super elasticity, high strength, and low density. Memory of its good corrosion properties and biocompatibility.

Name: NiTi alloy plate
Brand: Nitinol 55 Nitinol60
Implementation standard: ASTM2063
Place of production: Baoji, China
Density: 6.4 g/cm3
Surface treatment: sandblasting, polishing, grinding
Heat treatment: annealing, solid solution

1. High strength: Its strength is higher than pure titanium, but lighter than stainless steel.
2. Low density: Its density is lower than stainless steel, so it has great advantages in lightweight applications.
3. Corrosion resistance: Its corrosion resistance can resist the erosion of many chemical substances.
4. Good compatibility: Because of its biocompatibility, it is often used in the manufacture of implants in medicine.

1. Characteristics of shape memory: the function of returning to its original shape at a specific temperature. It will form a new shape when the temperature is low, and when the temperature rises to a certain temperature, it will return to its original state.
2. Superelasticity: It is caused by the martensitic phase change in titanium-nickel alloy. When external force is applied, a phase change occurs, which in turn leads to elastic changes in the titanium alloy. However, when the external force is removed, the martensite phase will return to its original form.
3. Anti-corrosion performance: A dense oxide film can be formed on its surface, which can further prevent corrosion of the alloy. In titanium-nickel alloys, titanium acts as a passivator to form a protective film, while nickel can improve the corrosion resistance and wear resistance of the alloy.
4. Gentle correction power: Currently, the tooth straightening wires commonly used in commercial use are mainly stainless steel and cobalt-chromium-nickel alloys. Titanium-nickel alloy has softer correction power and can better protect our teeth and periodontal tissue. It also reduces pain and discomfort.
5. Anti-toxicity: The oxide film formed on the surface of titanium-nickel alloy can resist and prevent harmful substances from intruding into the interior of the alloy, thereby protecting it from corrosion and damage. Because of its good biocompatibility and corrosion resistance, titanium-nickel alloy is often used as human implants, such as artificial joints, dental implants, etc.

1. Prepare a proportion of titanium and nickel materials.
2. Smelt the prepared proportion of materials until they are in a molten state for subsequent processing.
3. Pour the better smelted material into the mold, and cast it into the shape you want after cooling.
4. Roll the cast plate, and reduce its thickness and increase its strength through repeated rolling.
5. Post-heat treatment: We perform heat treatment on the rolled plate to improve its mechanical properties and its corrosion resistance.
6. Surface treatment: Polishing, pickling and other processes are performed on the plate to improve its surface quality and corrosion performance.

Medical devices: such as prosthetics, dental implants, pacemakers, etc.
Aerospace: some aircraft engine parts, some spacecraft parts
Chemical industry: It can be used to manufacture chemical pipelines, storage tanks, and chemical reactors
Automobile manufacturing: automobile exhaust pipes, engine parts, and its suspension systems, etc.
