The materials we typically manufacture our springs and wire forms are:
- Hard Drawn Spring Wire- A popular spring wire for commercial mechanical applications, it is a medium carbon, cold drawn wire.
- Galvanized Hard Drawn Spring Wire- Hard drawn wire that has been pre-coated/galvanized; no need for plating. It is good for spring designs that will have a high propensity to tangle or are delicate as the plating process is a bulk operation. Rack plating is an alternate but will be more expensive.
- Music Spring Wire- A tough material with a high tensile strength that can withstand higher stress under repeated loading than other materials. It has an excellent fatigue life and can be plated after forming.
- Galvanized Music Spring Wire- Music wire that has been pre-coated/galvanized; no need for plating. It is good for spring designs that will have a high propensity to tangle or are delicate as the plating process is a bulk operation. Rack plating is an alternate, but will be more expensive.
- Oil Tempered Spring Wire- Cold drawn and heat treated before coiling. Subject to hydrogen embrittlement if plated.
- Stainless Steel Spring Wire- A general purpose spring wire with good tensile strength and high corrosion resistance.
- Phos Bronze Spring Wire- The most popular copper-based wire, providing good corrosion resistance and electrical conductivity.
- Beryllium Copper Spring Wire- Good corrosion resistance and electric conductivity.
- Chrome Vanadium Spring Wire- Cold drawn and heat treated before fabrication. Suited for high stresses and loads.
- Chrome Silicon Spring Wire- Cold drawn and heat treated before fabrication. Used for applications that are exposed to considerable shock and extreme heat.
