Material: Commonly manufactured from high-grade steel, with stainless steel options available for enhanced corrosion resistance.
Wire Diameter: Typically ranges from 0.1 mm to 10 mm, depending on required strength and dimensions.
Outer Diameter (OD): Varies according to the design and application, with a broad range of possibilities.
Coil Diameter: Refers to the diameter of the coil itself, influencing flexibility and compression performance.
Free Length: The overall length of the spring when unloaded.
Active Coils: The number of coils actively contributing to the spring's elasticity.
Load/Force Rating: Defines the force exerted by the spring when compressed or extended, expressed in Newtons (N) or pounds-force (lbf).
Spring Rate: Indicates the force required to compress the spring over a set distance (N/mm or lbf/in).
Surface Finish: May be specified for functional or cosmetic purposes, particularly in visible applications or those requiring corrosion protection.
End Types: Options include closed and ground, open, or custom ends with hooks or loops for attachment.
Application: A brief description of the spring's intended use, including compliance with industry standards where necessary.
