Types of compression springs and their materials

Compression springs are a common mechanical part that is mainly used to withstand axial pressure. Compression springs can be divided into many types depending on their shapes and uses, and their material choices are also diverse. The following is some detailed information about the types of compression springs and their materials.
一、Types of compression springs
There are many types of compression springs, mainly including the following:
1. Cylindrical shape: The cross-section of the spring is circular and the overall shape is cylindrical. Simple in structure, easy to manufacture, and suitable for most conventional applications.
2. Conical shape: The cross-section of the spring gradually changes to form a conical shape, which can provide greater travel in a limited space.
3. Central convex shape: The middle part of the spring has a larger diameter and smaller ends. Suitable for applications that require large deformations in a smaller space.
4. Central concave: The middle part of the spring has a smaller diameter and larger ends, similar to the convex shape, but is more suitable in some specific applications.
5. Non-circular: Including a variety of cross-section shapes such as rectangles and multi-strand steel, customized according to specific needs to adapt to special installation space and load requirements.
二、 Material selection
The material selection of the compression spring is crucial to its performance. Common materials include:
1. Round: The most commonly used cross-section shape is usually made of round metal wire. Simple to manufacture, low cost, and suitable for most conventional applications.
2. Rectangular: Made of metal wire with a rectangular cross-section. Greater loads can be achieved in the same space, making it suitable for applications that require high loads.
3. Multi-strand steel: It is made of multiple strands of steel yarn rolled. Provides higher strength and durability for applications requiring high strength.
To sum up, there are many types of compression springs, and appropriate shapes and materials can be selected according to specific application needs. Whether round, rectangular or multi-strand steel, each material has its own unique advantages and application scenarios.
