Compression Springs: Product Details & Specifications

Product Overview
Compression springs are open-coil helical springs designed to provide resistance to axial compressive force. They are one of the most widely used spring types across industries due to their ability to store and release energy, absorb shock, and maintain force between contacting surfaces.

Key Features

• High Durability: Manufactured from high-quality materials such as stainless steel, music wire, or chrome silicon for long service life.

• Precision Engineering: Precisely wound to meet exact load, travel, and dimensional requirements.

• Wide Range of Applications: Suitable for automotive, industrial machinery, electronics, medical devices, and consumer products.

• Customizable: Available in various sizes, wire diameters, coil counts, and end configurations (closed, open, or ground ends).

Technical Specifications

• Materials: Music Wire (ASTM A228), Stainless Steel (302/304/316), Chrome Vanadium, Phosphor Bronze, etc.

• Wire Diameter: 0.1mm – 10mm (custom sizes available)

• Outer Diameter: 0.5mm – 150mm

• Free Length: 1mm – 500mm
