The nitinol #1 wire has a super-elastic temper, an oxide finish, and a standard tolerance, and meets American Society for Testing and Materials International ASTM F2063 specifications. Nitinol #1 provides corrosion resistance and has a super-elastic temper, which is spring like and ensures that the wire returns to its original shape after bending. The material is nonmagnetic and can be heated to a certain temperature to enable shape-memory characteristics. The oxide finish provides mild corrosion resistance.

Nickel titanium, also known as nitinol, is a corrosion-resistant metal that can exhibit shape-memory characteristics. When in its shape-memory temper, the material can be contorted but will return to its original shape when heated to a specific temperature.

Tensile strength, used to indicate the material€s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Magnetism characterizes how much the material is repelled by or attracted to a magnet.
