Technical Information for Custom Spring Designs

Industrial Spring specializes in manufacturing custom springs and wire forms from a broad range of material types. Some of the most common types we create include music wire, hard drawn, stainless steel (type 302, type 316 and type 17-7 PH), chrome silicon, and phosphor bronze. Some of these materials are readily available in pre-plated forms which can sometimes be utilized to save cost over having the parts plated after they are produced.   The Properties of Materials lists common wire materials used for springs and wire forms. It also lists common flat stock or strip materials used in stampings. The attached guide shows the minimum tensile strength, operating temperatures, hardness, chemistry information and suitable uses for each material.
