Precision Coil Spring is a world leader in manufacturing close tolerance springs, stampings, rings, wire and flat forms using exotic alloys.

Precision Coil Spring, located in El Monte, California, has been manufacturing custom designed springs since 1951. Although we use all the common steel and copper alloys, we specialize in more exotic alloys; in particular, titanium, Inconel, Elgiloy, Hastelloy, 17-7PH, and other stainless steels. In addition to compression, extension and torsion springs, we manufacture wire forms and flat forms on 4-Slide equipment, and we make value-added assemblies and various ring designs. We are ready to assist you with your spring requirements.

Precision Coil Spring manufactures product using all alloys that meet formability requirements and the physical characteristics associated with specific spring applications. Among the alloy families are: carbon steel, alloy steel, 300 series stainless steel, precipitation hardened stainless steel, nickel-based, cobalt-based, copper-based, and titanium.

PCS is one of the few spring manufacturers with extensive experience using exotic alloys, in particular titanium, a difficult alloy to form.
