A compression springs are coil springs storing energy when they are closed by a force. Compression springs are designed to operate with a compression load, so the compression spring gets shorter as load is applied to the spring. Stored energy in the spring is brought back to original state after force is removed to lengthen the spring and push against the object that compressed it.
 
Mechanical springs are of many forms out of which most common spring is compression spring. Compression springs can further be categorized as Conical Springs, barrel springs and hour glass spring to name few.
 
From the simple writing pen on car, compression springs have many uses, The function of each small or big machine is determines by the compression spring. For example, how would a ride in that car feel if there were no compression springs to support the shock absorbers?
 
A compression spring has elasticity born in the spring wire  used to store mechanical energy. Compression springs are usually made out of spring-tempered steel or from age-hardened spring material. Small compression springs can be wound from pre-tempered material, larger compression springs are made from annealed steel and hardened after winding. Some non-ferrous spring materials including; phosphor bronze,Inconel  Elgiloy , are used for compression springs requiring corrosion resistance.
