Daily knowledge and classification of spring

According to the nature of the force, springs can be divided into: tension springs, compression springs, torsion springs and bending springs.
According to the shape, it can be divided into: coil spring, disc spring, ring spring, wave spring, leaf spring, frustum scroll spring, spring (coil spring), torsion bar spring, floor spring, circlip, special-shaped spring, etc.
According to the production process, it can be divided into: cold coil spring and hot coil spring (the wire diameter is smaller than the fixed length, usually the cold coil method is used, and the wire diameter is larger than the fixed length, the hot coil method is used).

Frequently Asked Question

Do you have any question?

Beryllium copper (BECU) is often used in spring clips and flat spring production because of its great strength. It yields the same spring force as carbon steel at a fraction of the thickness.

Beryllium copper spring is a mechanical part that uses elasticity to work. Parts made of elastic beryllium copper material deform under the action of external force, and return to the original shape after removing the external force. Generally made of C17200 beryllium copper.

Beryllium copper is a non-ferrous alloy used in springs, spring wire, load cells, and other parts that must retain their shape under repeated stress and strain. It has high electrical conductivity, and is used in low-current contacts for batteries and electrical connectors.

Copper alloy springs have good electrical conductivity, thermal conductivity, non-magnetism, and have good corrosion resistance and wear resistance, especially copper springs will not produce sparks when they are hit. Springs made of this material are ideal for use in marine, chemical and instrumentation and electrical industries.
