Specification Brand : Shapiro Metal Supply BulletPoint1 : [Spring Steel Wire] - The diameter of the spring steel wire is 1mm, The length is 2m/7ft, you will receive 1 pcs spring steel wire, please choose the appropriate size according to your needs BulletPoint2 : [Spring Steel Wire] - The nitinol wire is made of nickel-titanium, corrosion-resistant, not easy to rust, suitable for long-term use in seawater environment, with strong corrosion resistance, cold bending is not easy to deform, and can be used for a long time BulletPoint3 : [Feature] - The expansion and contraction rate of spring steel wire is above 20%, which makes it have excellent performance in applications that require large deformation. It has super elasticity and can quickly return to its original state after being subjected to external force. BulletPoint4 : [Easy to Operate] - Memory alloys deform in low temperature environments. When the temperature exceeds 40°C or is below 0°C, the elasticity of the memory wire reduces and it can be bent and folded into other shapes at will. When the temperature is kept at 0°-40°C, the memory wire can be bent arbitrarily and still bounce back to a straight line. BulletPoint5 : [Wide Application] - It is mainly used for mobile phone antennas, optical glasses frames, headsets, fishing hooks, and fishing rods. It can be used in teaching experiments and meet the needs of various projects.
