Other Mechanical SpringS and Components
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).
Depending on the application, the correct material may make or break a spring’s performance. Factors such as operating temperature, corrosion resistance requirements, and spring characteristics required, fatigue and creep have to be considered during the material selection.
