Memory steel ring: What are the applications of memory steel ring?

The memory underwire is a new type of nickel-titanium shape memory alloy bra ring. After heat treatment, it is put into the bra. The shape is beautiful and stable, soft and elastic, without worrying about deformation. The phase transition temperature of this material is 25 degrees, the softness is below 25 degrees, and it can be hand washed by machine. When the body temperature is close to body temperature, it will automatically return to the bra shape setting state, which is the shape memory function. This material will not rust and is non-toxic, so no coating is needed, and it will not cause itching after use, because this material will not release substances harmful to the skin.

　　 Nitinol shape memory alloy: It is an alloy that can automatically restore its plastic deformation to its original shape at a certain temperature.

In addition to its own unique shape memory system function, Nitinol shape memory steel ring also has excellent development characteristics such as light material, wear resistance, corrosion resistance, high toughness, super elasticity, non-toxicity, and biotechnology compatibility with the human body. .

　　 Nickel-titanium memory alloy is mainly used in aerospace and medical devices, such as esophageal stents, biliary stents, urethral stents, blood vessel stents, contraceptive rings, minimally invasive surgical tooth extractors, dental wire arches, spectacle frames, etc. Obviously, the biocompatibility of this material implanted in the human body is unmatched by other materials.

The memory steel ring has a shape memory effect and phase change super (or pseudo) elasticity. Its pseudo elastic (or super elastic) can recover variable up to 10% to 20%, which is two orders of magnitude higher than general materials. Shape memory alloy developed at home and abroad The bra mainly uses the phase change superelasticity of the memory steel ring, which originated from the application of superelastic nickel-titanium alloy in the steel wire reinforcement developed by Japan, called the metal brace, which provides better comfort because it has a lower Compared with traditional steel wires and super-elastic memory steel rings, the elastic module resists deformation caused by repeated washing and drying.

　　 The above is the application of memory steel ring introduced for you, hope it will be helpful to you!
