Aluminum wire and copper wire difference
The colors are different. The color of copper wires is generally yellow to red or purple, while the color of aluminum wires is gray and white. Different flexibility. Copper wire has better flexibility, can bend freely and is not easy to break; The flexibility of aluminum wire is poor, can not be bent at will, otherwise it is easy to break. The resistivity is different. The resistivity of copper wire is small, the conduction effect is good, and the power loss is low. The resistivity of aluminum wire is large, which easily leads to heating and power loss. The stability is different. Copper wire oxidation resistance, corrosion resistance, good stability; The aluminum wire is easy to oxidize, resulting in increased resistance and reduced load capacity, which may cause safety accidents. The load power is different. Under the same cross section, the load power of copper wire is higher than that of aluminum wire. Different ductility. The ductility of copper is good, while the ductility of aluminum is relatively poor. The intensity is different. At room temperature, the allowable stress of copper is higher than that of aluminum, especially at high temperatures. In addition, the two also have different prices, different weights and other differences. In practical applications, suitable wire materials can be selected according to specific needs and scenarios.
