Transboundary of copper materials: Multi-field innovation "wild", open a new chapter of development

On the grand stage of materials science, copper with its unique physical and chemical properties, like a cross-border superstar, shines in many fields. Along the way from the ancient Bronze Age, copper has not faded due to the passage of time. On the contrary, with the blessing of modern science and technology, it has set off innovation in many fields and opened a new chapter for its own development.

In the field of electronic information: Copper materials build high-speed information channels

In the era of rapid information transmission, the requirements of electronic equipment for signal transmission speed and stability are almost harsh. Copper, with its excellent electrical conductivity, has become the "pillar" in the field of electronic information. In very large scale integrated circuits, copper interconnects

replace traditional aluminum interconnects, greatly reducing resistance and increasing electron migration speed. According to research, the signal transmission delay of chips using copper interconnects can be reduced by about 30%, which lays the foundation for a substantial improvement in chip performance and promotes the development of computers, smartphones and other devices in the direction of thinner and higher performance.

In the construction of 5G communication base stations, copper is also indispensable. A large number of lines, radiators and radio frequency devices inside the base station are widely used in copper. The copper radiator uses its good thermal conductivity to quickly dissipate the heat generated by the base station equipment and ensure the stable operation of the equipment in a high temperature environment. In the signal transmission line, the copper cable, with its low loss and high bandwidth characteristics, ensures the high-speed and stable transmission of 5G signals, so that high-traffic applications such as high-definition video and cloud games can run smoothly, bringing people the ultimate network experience.

Energy and power field: Copper helps energy efficient transmission and storage

In the field of energy and power, copper is the key material to achieve efficient energy transmission and storage. In the construction of power grid, copper core cable assumes the heavy responsibility of power transmission. Compared with other materials, copper cable has lower resistance, which can effectively reduce

the power loss in the transmission process. According to statistics, under the same transmission conditions, the use of copper cable can reduce power loss by about 15%-20%, which for the world's huge power system, means that a lot of energy can be saved every year.

In the field of new energy, copper plays an important role in solar energy, wind power generation and energy storage systems. In solar photovoltaic panels, copper backplanes and copper interconnectors can improve the power generation efficiency and stability of photovoltaic panels. In wind turbines, copper windings are used to make the stator and rotor of the generator, whose high conductivity allows the generator to efficiently convert wind energy into electricity. In terms of energy storage batteries, the application of copper based materials has brought new breakthroughs in the improvement of battery performance. For example, copper-based electrode materials can improve the charge and discharge efficiency and cycle life of batteries, which provides strong support for the development of electric vehicles and large-scale energy storage systems.

Transportation: Copper materials improve the performance and safety of transportation vehicles

In the field of transportation, the application of copper has made an important contribution to improving the performance and safety of transport vehicles. In automobile manufacturing, copper is widely used in engine, brake system, electrical system and other key parts. In the engine, the copper alloy radiator can

quickly dissipate the heat generated by the engine to ensure that the engine can maintain the normal working temperature under various working conditions, and improve the reliability and durability of the engine. In the braking system, copper based friction material because of its good friction performance and wear resistance, is used to manufacture brake pads and brake discs, can provide reliable braking effect, to ensure driving safety.

In the field of rail transit, copper also plays a key role. The power supply system of subway, high-speed rail and other trains uses copper contact lines and pantograph slides to ensure that the trains can obtain electricity stably during high-speed operation. The high electrical conductivity and good wear resistance of copper ensure the reliability and service life of the power supply system, and provide guarantee for the efficient operation of rail transit.
