Compression Springs, also known as coil springs, are open-coiled steel wire in a variety of cross sections and forms for linear applications. As compression springs are compressed, they provide a force (push) to return the spring back to its normal height. The force produced by compression springs makes them an excellent component for storing energy, ideal for various applications. They are used in everyday items, such as pens, vehicles, and mobile phones. Compression springs can be manufactured in any size, with varying degrees of stiffness, known as spring rate.
