1. Load power: The electrical conductivity of copper wire is better than that of aluminum wire. The load power of copper wire is greater than that of aluminum wire with the same cross-sectional area of copper wire and aluminum wire.
2. Mechanical properties: Copper wire has better flexibility after annealing, easy to bend, strong fatigue resistance, and mechanical strength is much better than aluminum wire. The aluminum wire is relatively easy to break when bent.
3. Stability: Aluminum wire is very easy to oxidize, which will increase the resistance, reduce the wire load, and prone to safety problems. However, the copper core has excellent oxidation and corrosion resistance and better stability.
4. Resistivity: The resistivity of copper wire is small, about 60% of that of aluminum wire. The smaller the resistivity, the lower the power loss.
5. Life: The above-mentioned performance of copper wire is better than that of aluminum wire, which makes the use occasion and service life of copper wire much higher than that of aluminum wire.
Through the above comparison and introduction of aluminum wire and copper wire, I believe everyone should know the reason why copper wire is commonly used in modern families. When choosing wires for home decoration, you must use copper wires instead of aluminum wires. The conductivity of aluminum wire is poor, and the wire is prone to heat during use, which can cause loose joints and even fire. In addition, it should be noted during the construction that you cannot directly dig a groove on the wall to bury the wires, but should use a regular casing installation to avoid leakage and fire.
The ductility of copper is much better than that of aluminum, so the copper wire can withstand stretching. When we decorate the circuit, we have to go through bends and overlap the wires. This is a great damage to the wires; and the installation of the wires is It is worn in the pipe and hidden in the wall. Once a problem occurs, it is very troublesome to repair. The editor recommends that you don't save money on wires, and try to choose good quality copper wires.
