Load Requirements
Tensile strength and elastic limit must prevent yielding under operating stress.
Material Engineering
Engineering Materials for Precision Springs
Material selection controls load capacity, fatigue life, corrosion resistance, conductivity and performance across temperature extremes.
Material Selection Criteria
Our engineering review evaluates four primary factors when specifying wire or strip for custom manufacturing.
Fatigue Life
Dynamic applications require predictable cycle life without premature structural failure.
Corrosion Resistance
Material must withstand moisture, chemicals, salts and cleaning environments.
Operating Temperature
Properties and dimensions must remain stable across the thermal range.
