Extension springs are a type of coil spring that lengthens under the weight of a load. Extension springs resist pulling forces. In contrast to compression springs, extension springs are compact when resting and extended when under stress. They are designed so that their spiral wires are contiguous when there is no weight load and stretched apart when loaded.
Extension springs are made of various steel materials, including stainless steel, hard drawn steel, steel music wire, and spring steel. Spring steel is a special kind of steel with increased elasticity and return properties. The elastic ability of a spring enables it to return to its original position; however, this capability diminishes with use. In general, the larger the wire, the stronger the spring is. Decreasing the diameter of the coil is another way to increase spring strength.
Extension springs are used to hold two components together. They come in many different sizes are used in a variety of applications. Extension spring components are used in tape cassette players, balance scales, trampolines, washing machines, garage doors, and more.
