1pc/pack 1mm High Tensile Strength Music Wire Compression Spring, 11mm OD, 120mm Free Length, Suitable for High Load Applications, 1x11x120mm(1pc)

The current spring size is: wire diameter 1mm, outer diameter 11mm, inner diameter 9mm, free length 120mm, pitch 4.5mm Made of music wire, carbon content is about 0.80-0.85%, and contains a small amount of silicon and manganese elements, with high tensile strength and fatigue resistance After quenching, the material is cold drawn to ensure that there is no decarburized layer on the surface. After tensile test, winding test, torsion test and bending test, the performance is guaranteed to meet the standard This compression spring has uniform spacing and uniform force, eliminates stress concentration, prevents eccentric force, enhances structural stability, and prolongs service life It is mainly used to manufacture springs that bear dynamic loads, such as automobile suspension springs, mechanical valve springs, automobile manufacturing, precision machinery, household appliances and hardware tools
