Corrosion-Resistant Compression Springs

These springs are more corrosion resistant than standard compression springs. They're also easier to compress than standard compression springs. As you squeeze a compression spring, it pushes back to return to its original length. Spring rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the spring rate, the harder it is to compress the spring.
Cobalt-nickel alloy springs have excellent corrosion resistance as well as high strength.
