Typically, extension springs are made from materials such as steel, but there can be situations where other materials like rubber, plastic, or different metals are preferable. These less traditional materials prove useful when steel wouldn't adequately perform, particularly in highly corrosive environments. In such cases, plastic, for instance, would often deliver more longevity. This article will discuss these non-traditional materials in detail, focusing on their attributes, applications, and the factors to take into account when choosing them in spring design.




Exploring various extension spring materials can offer tailored benefits for different applications. Beyond the common use of steel and stainless steel, alternative materials may provide unique qualities to fulfill certain requirements. By considering non-traditional materials such as rubbers, selected plastics, and specific metals, properties like tensile strength and heat resistance become available and can be utilized based on the specific needs. Remember to examine the needs of your application when selecting an extension spring material. Such a selection process can extend the lifespan of your spring applications.
