Features of enameled cca wire

　　 1. DC resistivity: The DC resistivity of aluminum enameled wire is about 1.5 times that of pure copper wire; when the resistance value is the same, the weight of aluminum enameled wire is about 1/3 of that of pure copper wire

　　2. Solderability: The soldering tin of aluminum enameled wire joints requires special flux or aluminum solder wire

　　3. Light weight: The density of aluminum enameled wire is 1/3.3 of that of pure copper wire of the same wire diameter, which is very effective in reducing the weight of the coil; using aluminum clad wire instead of copper wire can save at least 60% of the cost.

　　Existing application areas of aluminum enameled wire

　　 1. All kinds of large, medium and small transformers;

　　 2. Inductance, electromagnetic coil;

copper magnet wire Welding instructions: When soldering, the soldering iron tip should be as close as possible to the body to be welded, and then the solder wire should be sent to the soldering iron tip to melt the soldering wire and complete the soldering (this method allows the flux in the soldering wire to fully contact the board surface to achieve good Welding effect); for the welding of enameled aluminum wire and copper wire (or aluminum wire), the two wires are usually connected by twisting after the paint is scraped, and the size of the twisting directly affects the welding effect, the twist (that is, the arc) The larger the amount of tin filling, the stronger the welding between the two wires; for the enameled cca wire that has just been welded, do not pull it by hand too quickly, wait for it to cool down completely, and then check its reliability; For the unused solder wire, use a lighter to burn the wire head into a ball shape to avoid the loss of liquid flux in the wire and affect the next welding.
