International Compression Springs

A compression spring offers resistance to the axial compressive force. It is an open-coil helical spring. They are generally coiled as constant diameter cylinder.

Common forms: - Conical, Concave (barrel), Convex (hourglass) and various combinations of above.

The space allotted will decide the allowable solid height, inner diameter and outer diameter of compression springs. Along with the load and deflection, the dimensional limits will decide the stress level. Therefore to avoid any design changes, sufficient care should be taken to decide allotted space.

Round wire is preferred over square, rectangular or some special section because of its easy availability Coiling operation produces stress so springs must be stress relieved.

Spring Materials
Common spring materials include stainless steel, alloy steels, carbon steels and some non-ferrous materials. IIS also produces spring from Exotic material like Inconel, Monel, Nimonic, Hastelloy etc.
