This page explains how Compression Spring is classified within Fabricated Metal Product Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A compression spring is a helical coil designed to resist axial compressive forces and store mechanical energy, commonly used in automotive, industrial, and consumer applications.
Technical details and manufacturing context for Compression Spring
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Wire Diameter | 0.1–12 mm | Range for standard compression springs; custom sizes available.ISO 10243 |
| Outer Diameter | 1.0–100 mm | Typical range; larger diameters on request.ISO 10243 |
| Free Length | 2–500 mm | Unloaded length; tolerances per ISO 10243.ISO 10243 |
| Spring Rate | 0.1–500 N/mm | Force per unit deflection; depends on geometry and material.ISO 10243 |
| Maximum Deflection | 50–80% of free length % | Typical safe deflection; solid height must be considered. |
| Operating Temperature Range | -40 to 250 °C | Depends on material; stainless up to 250°C, music wire up to 120°C. |
| Surface Finish | Shot-peened, ground, or plain | Shot-peening improves fatigue life; grinding ends for squareness.DIN 2095 |
| End Type | Closed & ground, closed, plain | Closed & ground is common for precision applications.DIN 2095 |
| Tensile Strength | 1200–2200 MPa | Varies with wire diameter and material grade.EN 10270-1 |
| Fatigue Life | 10^6–10^7 cycles | For dynamic applications; depends on stress and surface treatment. |
| Tolerance Class | Grade 1, 2, 3 | Grade 1 is finest; typical for precision springs.DIN 2095 |
| Solid Height | 0.8–0.9 × free length mm | Height when coils are fully compressed; must be less than free length. |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

Standard compression springs have wire diameters from 0.1 to 12 mm, outer diameters from 1.0 to 100 mm, and free lengths from 2 to 500 mm. These are reference ranges; custom sizes may be available. Always confirm exact dimensions for your application with the supplier.
Spring rate (k) is the force required to compress the spring by one unit of length, typically expressed in N/mm. It depends on wire diameter, coil diameter, number of active coils, and material shear modulus. For a given spring, it is constant within its elastic range.
Common materials include ASTM A228 music wire, ASTM A313 stainless steel 302/304, ASTM A401 chrome silicon steel, EN 10270-1 patented cold drawn wire, and GB/T 4357 carbon steel wire. Each has different temperature limits and fatigue characteristics.
Relevant standards include ISO 10243, DIN 2095, EN 13906-1, GB/T 23935, and SAE J157. These provide guidelines for dimensions, tolerances, and testing. They are references for procurement and verification, not proof of certification. Verify compliance with the manufacturer.
