Torsion Springs is a type of spring that works by torsion or twisting, which operates by linear compression or extension, torsion springs exert a torque or rotational force. They typically consist of a helical coil and arms that are attached to other components. These are commonly used to apply torque or force rotationally, such as indoors, lids, or any application where rotational force is needed. Torsion Springs can be made from various materials, including high-carbon steel, stainless steel, or other alloys. The choice of material depends on factors such as the application requirements, environmental conditions, and the desired durability of the spring.
