Why is copper coil better than aluminum coil in terms of coil conductivity? First of all, the conductivity of aluminum is lower than the conductivity of copper. In order to keep up with the copper coil, the aluminum magnetic wire may need a larger cross section so that they can provide the same level of conductivity. That is, the winding with the aluminum wire will need a larger volume than the copper coil of the same size Secondly, from the chemical properties, the aluminum oxide much faster than other metals, if aluminum exposed to air, it will completely oxidized in just a few days, and a fine white powder Therefore, in order to properly connected in order to ensure good electrical conductivity, must piercing the oxide layer of the aluminum electromagnetic wire, aluminum to prevent further contact with air Finally, from a cost-effective point of view, aluminum coil of the same performance requires more turns and larger diameter wire, which is more expensive and less economical than copper coil. If the coil is only occasionally operated for a short time without high coil efficiency and volume requirements, aluminum wire can be used In recent years, some manufacturers in order to reduce the cost of materials using aluminum wire pretending to be copper wire to cheat customers this behavior not only caused harm to customers but also disrupted the order of fair competition in the market Dongguan Fuying electronics since its establishment in 2003, has been adhering to the principle of customer rest assured, responsible for the user Over the years, we insist on the use of high-quality raw materials. In order to ensure the quality of products, we only choose A-level raw materials suppliers. All raw materials are 100% reliability test when entering the factory to ensure that the coil quality meets customer requirements。
