Flat spring steel wire is a specialized type of metal wire characterized by its rectangular or flat cross-section, which differentiates it from the more common round wire. This unique shape imparts distinct properties that make it indispensable in a variety of industrial applications. The main functions of flat spring steel wire include providing mechanical support, shock absorption, and electrical conductivity in numerous devices. Technologically, it is produced through a precision rolling process that ensures high dimensional accuracy and consistent mechanical properties. The material's flexibility and resilience make it ideal for use in the creation of springs, clips, and other components that require elasticity and durability. Common applications include automotive parts, electrical appliances, and mechanical instruments, where the flat profile offers space and weight savings.
