JIS Standard Die Springs

JIS Standard Brown Color Die Spring (JIS B 5012) is extra heavy duty die spring which work maximum 20% of its length mens its can return maximum load capacity, Die springs are manufactured from rectangular wire with rounded corners. Die springs work similarly to standard compression springs, where energy is stored when a load is applied and the spring tries to keep two components separate. A tighter spring winding yields a higher spring rate for springs manufactured from th same wire. Oil-tempered steel is a common material for die springs. Chrome alloys are also common die spring materials, with a chrome layer adding wear and corrosion resistance. Less common, but also much stronger, is chrome silicon or chrome vanadium, which improves dimension accuracy, minimizes individual stress points, and can operate in higher temperatures. These metals allow a pliable layer of colored vinyl to be applied to the spring, indicating a spring's working load.
