Air conditioner and freezer The temperature control of air conditioners and freezers is mainly achieved by evaporation and condensation of copper tubes in heat exchangers. The size and heat transfer performance of the heat exchange tubes determine the effectiveness and miniaturization of the entire air conditioner and refrigeration unit to a large extent. The special-shaped cop...

Aircraft The navigation of the aircraft is also inseparable from copper. For example, wiring, hydraulic, cooling and pneumatic systems in aircraft use copper, bearing retainers and landing gear bearings use aluminum bronze pipes, navigation instruments use anti-magnetic steel alloys, and many instruments use broken copper elastic components. www.feihongalloys.com

Railway The electrification of railways requires a large amount of copper and copper alloys. More than 2 tons of profiled copper wire are required for overhead conductors per kilometer. In order to increase its strength, a small amount of copper (about 1%) or silver (about of%) is often added. In addition, the motors, rectifiers, and control, braking, electrical, and signal sys...

car Automobiles use 10 to 2 I kilograms of copper per car, depending on the type and size of the car. For cars, they account for about 6 to 9% of their own weight. Copper and copper alloys are mainly used in radiators, brake system piping, hydraulics, gears, bearings, brake linings, power distribution and power systems, gaskets, and various fittings, fittings, and trims. Among ...

Lead frame In order to protect the normal operation of an integrated circuit or a hybrid circuit, it needs to be packaged; and when packaged, a large number of connectors in the circuit are led out of the sealed body. These leads require a certain amount of strength to form the support skeleton of the integrated package circuit, called the lead frame. In actual production, for ...
