Depending on the types of adhesives, types of copper alloys can be divided into rubber series, plastic series and asphalt series. Asphalt series damping materials are easily accessible, cheap and versatile. The greater the force value of the loss factor, the better the damping performance. Damping also extends the service life of metallic structures under strong acoustic excitation. This kind of new metal alloy which is suitable for the circuit board of electronic instruments to further ensure the stability and reliability of the instrument. In addition to being widely used in noise control engineering, different types of copper alloys are also widely used in road transport, railway transport, ship transport, military tanks, aerospace and other fields.
