A spring is an elastic object used to store mechanical energy. Springs are usually made out of spring steel. 

There are a large number of spring designs; in everyday usage the term often refers to coil springs.

Springs are made from a variety of elastic materials, the most common being spring steel. Small springs can be 

wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after fabrication. 

Some non-ferrous metals are also used including phosphor bronze and titanium for parts requiring corrosion resistance and beryllium copper for springs carrying electrical current (because of its low electrical resistance).
