I don't know if you know the application of copper in the transportation industry? Then let's talk about the application of copper in the transportation industry.

Ship copper alloys, including aluminum bronze, manganese bronze, aluminum brass, gunmetal (tin-zinc bronze), cupronickel and nickel-copper alloy (monel), are one of the standard materials for shipbuilding. Copper and copper alloys generally account for 2% to 3% in the dead weight of warships and merchant ships, such as aluminum bronze propellers, bolts, rivets, condenser pipes, and copper-containing clad paints.

Automotive copper and copper alloys are mainly used in radiators, brake system pipelines, hydraulic devices, gears, bearings, brake pads, power distribution and power systems, gaskets, and various joints, accessories and trims, etc. Copper is 10-20kg, and copper for cars accounts for about 6%-9% of its own weight.

Motors, rectifiers and control, braking, electrical and signaling systems on railway trains all rely on copper and copper alloys to work. In addition, the electrification of railways requires a large amount of copper and copper alloys, and a special-shaped copper wire of more than 2t is required for each kilometer of overhead conductors.

The wiring, hydraulic, cooling and pneumatic systems in the aircraft need to use copper, the bearing retainer and landing gear bearings are made of aluminum bronze pipes, and the navigation instruments are made of diamagnetic copper alloy.
