The selection of the raw material depends on the environmental factor and the application of the product. The spring material can be broadly classified into groups such as high carbon spring steel, alloy spring steel, stainless steel, phosphor bronze and copper base alloys. At Goldstar Springs manufacture springs from all the above raw materials of IATF:16949 standard.

Valve Springs are manufactured using high-tech, super-clean chrome silicon alloy materials that are held to tighter stress relief and shot peen tolerances, making them stronger and more efficient than others on the market. A micro-peening process is used to increase durability and longevity of the spring, which means you can push harder for longer. In addition, the added heat treatment reduces load loss during operation. Some springs are also nitrided for racers who are looking to increase lift capacity and number of cycles over the life of a spring. Wire diameters from 0.80 to 8.00mm.
