Enameled copper and aluminum as signal transmission is possible, but now as power transmission, it is easy to make mistakes, and the life expectancy of its products will be greatly shortened. In fact, when using CCA wire, pay attention to the oxidation protection under the enameled wire to ensure the effective combination of copper and aluminum, which can be used for a long time.
Copper-clad aluminum and enamel copper-clad aluminum is actually not available in many places, but in fact, many companies are using transformers, which is very worrying. Copper-clad aluminum wire itself has a higher resistivity than copper and other cross-sections, and the temperature rise is related to the problem; the oxidizability of aluminum wire will further increase the lead resistance and take measures to prevent oxidation.
The most worrying thing is the combination of copper-clad aluminum and copper-aluminum. Industry insiders often say that metallurgical bonding is a true long-term reliability process. In the process of expansion and contraction, whether the combination of copper and aluminum has withstood the test. It has not really been shown.
The rectangular enameled wire can be used for mobile wireless chargers and should contain two flat coils. This is a new design and application, but some customers are still using round lines for design. If your customer is in the mobile wireless charger business, we recommend that you use flat enameled wires instead of round enameled wires. Because the round enameled wire is too hard to be wound, the volume of the round coil is larger than the flat coil.
The aluminium Magnet wire can also be used in car audio equipment. Usually, we line up the flat wire in a circular manner with the same center between two coils. For example, flat wires with dimensions of 0.042mm x 0.28mm and 0.09mm x 0.30mm use this winding process.
