Chemical composition classification and technical indicators of spring raw materials

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

A. Spring steel—carbon spring steel and alloy spring steel;

B. Copper alloy materials for springs-silico-manganese bronze, tin-phosphorus bronze, beryllium bronze, aluminum bronze;

C. 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.

D. Non-metallic materials include rubber, plastic, glass fiber reinforced plastic, carbon fiber, and air.
