Talking about the current situation of enameled aluminum wire industry

  • Time: 2022-08-04 18:26:22

The enameled aluminum wire has more excellent flexibility, lightness and high conductivity. The enameled aluminum wire is mainly used in the three fields of microwave oven transformers, TV degaussing coils and small motors for most household appliances. Enamelled aluminum wire is not suitable for use in products in long-term uninterrupted occasions, so it can only be used in fields with relatively simple process technology.

Advantages of enameled aluminum wire

  1. Both copper and aluminum have good electrical conductivity, thermal conductivity and corrosion resistance, so they are often used to make various wires, cables and current-carrying parts. The density of aluminum is 2.7 grams per cubic centimeter, while the density of copper It is 8.9 grams per cubic centimeter. The flexibility of aluminum conductors is better than that of copper conductors. In contrast, it is easier to make coils. Because the surface of the enameled aluminum wire has a solid oxide film, it has good insulation effect and long service life. .
  2. Due to the good insulation of the film layer of the aluminum wire, its heat-resistant temperature is 20C higher than that of the copper wire.
  3. The biggest advantage of using aluminum wire is that the weight is 1/3 lighter than that of copper wire, which greatly reduces production costs and is easy to attach to fixtures.

When the copper price is as high as 70,000 to 80,000 yuan per ton, the cost of enameled round copper wire accounts for 40--50% of the cost of some motors. With the sharp surge in copper prices and the current fluctuations in copper prices, the cost of materials has been extremely challenged, which has accelerated the development of enameled aluminum wires. In order to reduce costs, many companies have begun to use enameled aluminum wire instead of enameled round copper wire as the winding material.
