Choosing Spring Materials: A Comparison of Common Spring Steels
Load type, stress level, temperature, environment and life all affect material choice. Here is how common spring steels compare.
Carbon spring wire is economical for general use; music wire suits small, highly stressed springs; 60Si2MnA and 50CrVA are the workhorses for hot-coiled springs, disc springs and leaf springs; stainless steel resists corrosion; bronzes are conductive and non-magnetic. Tell us your working conditions and we will recommend the right material.
