How to remove paint for magnet wire enameled wire

As a representative product of magnet wire, copper-clad aluminum wire is a bimetallic composite wire that is combined with copper layers on the aluminum core. Reasonable use of the properties of different metals, so as to achieve the characteristics of reducing production costs and facilitating engineering construction.

Copper-clad aluminum wire is used in the cable television industry, and copper-clad aluminum wire has become the standard material for coaxial cables in the United States. Because the high-frequency signal transmission runs on the outer layer of the wire, the copper-clad aluminum wire can replace the copper wire of the same specification. In low-frequency applications, the load capacity of copper-clad aluminum is 65% of that of copper wires of the same specification. Because of its light weight, it is softer than copper when large wire sizes are required. Copper-clad aluminum is used for battery cables, welding cables, Building cables and electromagnetic wires are also the best wire materials.

Compared with pure copper wire, copper-clad aluminum wire has the advantages of good electrical conductivity and light weight, which is economical, and has good flexibility during construction and is easy to operate. The length ratio of the same wire weight is 2.45:1, so buying 1 ton of copper-clad aluminum wire is equivalent to buying 2.45 tons of pure copper wire, which has the advantage of saving costs.

Compared with pure aluminum wire, copper-clad aluminum wire has high electrical conductivity, and also increases tensile strength and elongation. The solderability like copper wire greatly increases the mechanical properties and applicability of the product.

How to remove paint for magnet wire enameled wire, we can roughly divide it into the following three methods according to different conditions, equipment and needs.

1. For ordinary thin wires, it can be directly tinned when placed on a soldering iron at 400 degrees Celsius. For thick wires, we do not recommend the method of fire roasting, which will make the magnet wire oxidize and affect its properties, and even if it is reluctantly completed in time, it will be found that there will be some pores on the surface of the tin.

2. We can also apply rosin on the broken end of the enameled wire, and put the section into the soldering iron to melt tin. The section has no paint, so it will be tinned quickly, and the surrounding area will also increase with the temperature without adhesion. Remove the paint and tin, we just need to control the temperature.

3. Here we recommend the third type of paint. Qualified paints do not damage or corrode the metal. They can remove the paint on the surface of the electromagnetic wire. There are bad consequences or residues on the wire surface. The core wire has excellent weldability after removing the paint. Now many industrial manufacturing sites use this method for batch processing. Now it has replaced the old method of scraping and burning with a knife, and the cost is leaping.
