What is the difference between aluminum wire and copper wire?
In the process of using various household appliances, we inevitably need to use wires. There are two types of wires on the market now, aluminum wire and copper wire, but most people do not have much understanding of these two types of wires. For example, what is the difference between aluminum wire and copper wire?
What is the difference between aluminum wire and copper wire?
- 1. The prices are different. The price of aluminum wire is much lower than that of copper wire. The price of normal copper wire is 3.5 times that of aluminum wire, and copper wire is heavier than aluminum wire.
- 2. Different flexibility, copper wire has better flexibility, simpler shape, stronger fatigue resistance, and aluminum wire is easily broken when bent.
- 3. The resistivity of copper wire is different, generally 1.68 times lower than that of aluminum wire, so aluminum wire consumes more electricity, generates severe heat, and easily affects electrical efficiency.
- 4. Due to differences in stability, aluminum wires are prone to oxidation during use, leading to increased resistance and reduced load capacity, resulting in safety accidents.
- 5. The load power is different, and for copper and aluminum wires with the same cross-sectional area, the load power of copper wire is generally higher than that of aluminum wire. If both are 2.5 square meters and aluminum wire can withstand 2500 watts, then copper wire is 3000 watts.
2、 How to choose household wires?
When choosing wires, it is best to use copper wire and avoid aluminum wire as much as possible, because aluminum wire has poor conductivity and can generate heat during use, which has a high possibility of catching fire.
When we are carrying out wire construction, we should be careful not to directly set up wire slots on the wall. It is best to use a formal set for installation to avoid leakage or safety accidents.
The above is some information about wires. From the article above, it can be seen that although wires are divided into aluminum wire and copper wire, it is still better to prioritize copper wire when using wires because copper wire has better performance, while aluminum wire may have some safety hazards.
