💡 What determines the fatigue life of compression metal springs used in industrial applications? Proper material selection and geometry play a major role in longevity. * High carbon steel grades withstand repeated compression cycles best * Surface treatments like coatings minimize friction and environmental damage * Maintained tension ensures consistent performance over extended use * Correct wire diameter directly impacts overall resilience under load
