Enameled copper clad aluminum 
 Copper clad aluminum enameled copper clad aluminum material is used as the internal conductor of the new wire, between its characteristics between copper and aluminum, combined with the excellent conductivity of copper and aluminum light weight advantage. Copper prices have risen sharply in the current period, is an excellent alternative to enameled copper material, copper clad aluminum enameled copper magnet wire and there were significant advantages. 
 1, light weight 
 Copper wire density is the same diameter of the copper wire of 1 / 3, to reduce the weight of the cable and the coil is very effective in the field of voice coil, significantly improved product performance. 
 2, a good DC resistivity 
 DC resistivity of copper clad aluminum wire is approximately 1.5 times the copper wire Dacron; resistance is the same, its diameter is about 1.2 times copper, and copper clad aluminum wire copper wire weighs only 1 / 2. 
 3, good brazing of 
 Copper clad aluminum wire wrapped its surface a layer of concentric copper, it has the same with pure copper wire can be brazed, while aluminum do not like special treatment. 
 4, low cost of 
 Enameled copper clad aluminum wire and copper compared to that in some fields of use can reduce production costs by 30% -50%. 
 In recent years, enameled wire industry in national economic development in the important position and role of the more prominent, and as copper prices continued to rise, to the relevant enameled copper production and supply of raw materials manufacturers and a great impact. Enameled copper clad aluminum confirmed by the user can replace the copper wire, enameled wire industry, which gave the development of China's tremendous business opportunities and a broad market. 
 Most of the traditional use of copper as copper enameled wire material, is not only costly, but also by resource constraints. The company introduced a considerable copper clad aluminum enameled wire in the field of not only the equivalent (or super-effective) alternative to copper, but also greatly reduce the manufacturing cost, the alternative copper products, import substitution and development of national economy will related industries and fields of technology level and lower manufacturing costs play a powerful role.
