2, motor manufacturing: In the motor manufacturing, high conductivity and high strength copper alloy is widely used, the main copper parts are stator, rotor and shaft.

3. Communication cable: Due to the advantages of large current-carrying capacity of optical fiber cable, it constantly replaces copper cable on the communication trunk line and is rapidly popularized and applied.

4. Residential electrical circuits.

5, electric vacuum devices: electric vacuum devices are mainly high frequency and ultra-high frequency transmitting tube, waveguide, magnetron, etc., they need high purity oxygen free copper and dispersion enhanced oxygen free copper.

6, printed circuit: copper printed circuit, copper foil as the surface, pasted on the plastic plate as a support, the circuit wiring diagram is printed on the copper plate with the method of photography.

7. Integrated circuit.

8, lead frame: Copper alloy through alloying can control its performance in a large range, can better meet the performance requirements of lead frame, has become an important material of lead frame.
