Flat stainless steel spring strip
As with wire, there is a wide range of strip materials available to the spring manufacturer. As many parts produced in strip are not primarily used as a spring, many low strength alloys are used, generally for their formability and electrical conductivity. Strip materials can be obtained in different grades of hardness, and some spring materials are able to be heat treated to increase their strength and hardness. Due to the vast range of materials available this section will deal with carbon steels, stainless steels and copper alloys only.
