Chemical composition classification of spring raw materials

The spring raw materials are divided into two parts: metallic materials and non-metallic materials.

Metal materials include:

1, spring steel — carbon spring steel and alloy spring steel;

2, copper alloy materials for springs-silicomanganese bronze, tin phosphor bronze, beryllium bronze, aluminum bronze;

3. Elastic materials for special beads-stainless steel for springs, iron-based elastic materials, nickel-based elastic materials, cobalt-based elastic materials, and titanium-based elastic materials.

Non-metallic materials include rubber, plastic, fiberglass, carbon fiber, and air.
