Product Description

Product Description

The term Nitinol refers to the general term for those NiTi alloys.Nickel-titanium alloy is a shape memory alloy, which is a special alloy that can automatically restore its own plastic deformation to its original shape at a certain temperature, and has good plasticity.Its expansion rate is above 20%, its damping characteristics are 10 times higher than ordinary springs, and its corrosion resistance is better than the best medical stainless steel at present, so it can meet the application requirements of various engineering and medicine, and is a very good spring Functional Materials.In addition to its unique shape memory function, memory alloys also have excellent characteristics such as wear resistance, corrosion resistance, high damping and superelasticity.

Characteristics of Nitinol shape memory alloy(1) Shape memoryNickel-titanium alloy shape memory alloy will automatically restore its shape after a certain heat treatment. This change is the shape memory characteristic of nickel-titanium alloy shape memory alloy. Shape memory can be divided into one-way shape memory, two-way shape memory and full-process shape memory according to the recovery status.(2) HyperelasticityNickel-titanium alloy shape memory alloy will deform when it is subjected to external force, and it will return to its original shape after removing the external force. This is the superelastic characteristic of nickel-titanium alloy shape memory alloy. After the superelastic deformation of nickel-titanium alloy shape memory alloy, it will directly lead to martensitic transformation, and remove the external force, it will lead to reverse martensitic transformation.(3) DampingThe nickel-titanium alloy shape memory alloy has very good damping properties because of the self-adjustment of the phase transition and the interface and motion generated during the phase transition.(4) ResistivityDuring the deformation process of the martensitic nickel-titanium alloy shape memory alloy, the relationship between the resistance and the strain is linear. When the phase transformation occurs, the slope of the curve will decrease, but the linear relationship will be maintained before and after the martensitic phase.Application of Nitinol AlloyFAQAre you a trading company or a factory?
