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 pure copper wire
2. Solderability: aluminum enameled wire joint solder requires special flux or aluminum solder wire
3. Lightweight: aluminum enameled wire density is 1/3.3 of pure copper wire of the same wire diameter, which is very effective in reducing the weight of the coil; using our aluminum-clad wire instead of copper wire can save at least 60% of the cost.
aluminum enameled wire existing applications
1. All kinds of large, medium, and small transformers;
2. Inductance, electromagnetic coil;
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 tin-filled quantity, the stronger the welding between the two wires. For the enameled wire that has just been welded, do not pull it by hand too quickly, and wait for it to cool down completely before checking its reliability; For the used solder wire, use a lighter to burn the wire head into a ball shape to prevent the liquid flux in the wire from losing and affecting the next welding.
