What is the difference between a compression spring and a tension spring?
Although a tension and compression spring are both helical coiled springs, the difference in their functionality and purpose can be significant. In essence, tension springs are designed to bring components together, whilst compression springs are made to keep components apart.

Frequently Asked Question
Do you have any question?
The main function of tension springs is to allow for an outside force to create tension, and then use this energy to pull the components back together by reverting to its original shape. Tension springs are typically wound very tightly and are coiled closely together when at rest.
Extension springs with a high amount of tension, therefore taking a strong load to extend it. Also known as heavy duty tension springs.
The main difference is that tension springs are meant to hold two things together while compression springs are designed to keep components from coming together. While they work in opposition with each other, they are both necessary for different products.
There are many types of materials for tension springs, which can usually be selected according to factors such as the environment of use, the required elasticity and corrosion resistance. Here are some common spring materials: Steel: Steel is one of the most commonly used spring materials, has high strength and hardness, and performs well in high temperature and high pressure environments. Stainless steel: Stainless steel has excellent corrosion resistance and is often used in applications where oxidation and corrosion resistance is required. Cobalt alloys: Cobalt alloys have very high elasticity and wear resistance, and are commonly used in applications in high temperature, high pressure and strong corrosion environments. Copper: Copper spring has good electrical and thermal conductivity, and is commonly used in electronic devices, communication equipment and other occasions. Titanium alloy: Titanium alloy has light weight, high strength and excellent corrosion resistance, and is commonly used in aviation, aerospace and other fields.
The elastic coefficient of a spring is the ratio of stress to strain due to tension or compression per unit length, usually expressed in terms of elastic modulus E. The modulus of elasticity is an intrinsic physical quantity of a material and is related to the geometry of the spring and the material. The greater the elastic coefficient of the spring, the better its elasticity, and the smaller the amount of deformation per unit length.
