Materials for Custom Springs and Wire Forms

To meet your industry’s diverse needs, Master Spring specializes in manufacturing custom springs and wire forms from a broad range of material types. Some of the most common coil spring materials we use include music wire, stainless steel (type 302, type 316 and type 17-7 PH), hard-drawn wire, chrome silicon, and phosphor bronze. Coupling this selection with our years of expertise in the industry, we stand out by producing the types of springs and wire forms other manufacturers simply will not quote.

At Master Spring, we use a Properties of Materials Guide, which lists common wire materials used for springs and wire forms. It also lists common flat-stock or strip materials used in stampings. Explore the guide for nominal chemistry, minimum tensile strength, maximum operating temperatures, Rockwell hardness, and suitable uses for each material. Check out our list of spring materials below.
