What is Compression spring?Compression Springs are open-coil helical springs wound or created to oppose compression along the axis of wind. Helical Compression is the most typical steel springtime arrangement. These coil springs can function individually, though commonly assembled over a guide rod or equipped inside an opening.Typical Compression Spring Design TermsAccording to the Spring Manufacturers Institute Handbook of Spring Design, commonly used compression spring terminology includes the following:Wire diameter (d)Outside Diameter (O.D)Inside Diameter (ID)D coil diameter =Outside Diameter. (O.D. + I.D.)/2 or O.D. - d Free Length = The total length of a compression spring when it is unloaded.Pitch (P )= the distance between the wire centers in adjacent active coils. It is best practice to specify the number of active coils rather than the pitch.Compression Spring MaterialsZihuoli Spring custom compression springs from a variety of materials. Music wire, hard drawn, stainless steel (type 302, type 316), oil tempered, chrome silicon, and phosphor bronze are the most common material types for compression springs. We also make compression springs out of more exotic materials like Inconel, Monel, Beryllium Copper, and others.In order to provide our customers with the shortest lead times possible, we stock several of these material types in various diameters.Compression spring materials that are commonly used include:• Carbon Steel• Stainless steels• Alloy steel• Copper Base Alloy• Nickel Base Alloy• Cobalt-Nickel• TitaniumZihuoli Springs Capability for Different Compression Spring Body ShapesThere are four different body designs for compression springs are produced by Zihuoli Spring.
