Is it better to use copper wire or aluminum wire for household wires?

At present, household wires on the market are mainly divided into copper wire and aluminum wire. A lot of decoration Freshman is tangled. In order to ensure the safety of household electricity use, which one should be better? Next, I will analyze whether it is better to use copper wire or aluminum wire for household wires?

1. Load power: the conductivity of copper wire is better than that of aluminum wire. The load power of copper wire is greater than that of aluminum wire for copper wire and aluminum wire with the same cross-sectional area.

2. Mechanical properties: after annealing, copper wire has better flexibility, convenient bending, strong fatigue resistance, and mechanical strength is much better than aluminum wire. Aluminum wire is relatively easy to break when bending.

3. Stability: The aluminum wire is very easy to oxidize, which increases the resistance, reduces the wire load, and is prone to safety problems. However, the copper core has excellent oxidation resistance and corrosion resistance, and has 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. Service life: The above performance of copper wire is superior to that of aluminum wire, which also makes the use occasion and service life of copper wire much longer than that of aluminum wire

Through the above comparison and introduction of aluminum wire and copper wire, we believe that we should know the reason why copper wire is widely 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 easy to heat up when used, which will cause loose joints and even fire. In addition, during construction, it should also be noted that it is not allowed to directly dig trenches on the wall to bury wires, but should be installed with regular sleeves to avoid electric 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 the wires must overlap, which is a great damage to the wire; Moreover, the wires are installed in the pipes and hidden in the wall, which is very troublesome to repair once problems occur. Ruiyang Group suggests that people should not save money on electric wires and try to choose copper wires with good quality.
