1. Shape memory alloy spring (temperature control spring) can be used to control the water temperature of the bathroom water pipe: When the hot water temperature is too high, the water supply pipe can be adjusted by the "memory" function to avoid burns.

2. Can be made into fire alarm device and electrical equipment safety device. When a fire occurs, the memory alloy spring deforms, and the fire alarm device is activated to achieve the alarm purpose.

3. The spring made of memory alloy can be placed in the heating valve to maintain the temperature of the heating room. When the temperature is too low or too high, the heating valve is automatically opened or closed.

4. The assembly of NITI alloy on the nose bridge and ears of the eyeglass frame can make people feel comfortable and resistant to wear. The super-elastic NITI alloy wire is used as the eyeglass frame. Even if the lens is thermally expanded, the shape-memory alloy wire can hold the lens by the constant force of super-elasticity.

5. Memory steel rims made of the super-elasticity of memory alloys are softer and more flexible than stainless steel rims to better protect women's health
