Product Description

Bronze Strips

Bronze strip is copper with tin, aluminum, and trace elements as raw materials, through processing by ingots, hot rolled, cold rolled, heat treatment, surface cleaning, cutting, finishing and packing, materials with high yield strength, fatigue strength, elastic properties and excellent bending formability. It has been widely used in computer CPU socket, car terminals, mobile phone keypad, electrical and other high-tech electronics connectors.
