0.3mm 2uew155 Soldering Magnet Wire Polyurethane Enameled Copper

2uew155 Polyurethane enameled copper wire high quality

The selection of copper materials and the process of wire drawing are the keys to fine wire drawing. From the material 0.80mm copper wire to 0.011mm, it has to go through several procedures such as middle drawing annealing, small drawing annealing, fine drawing annealing, micro drawing annealing, etc. In order to ensure the softness of the enameled wire, the copper wire cross-sectional area is compressed by 90% every time. Annealed once. The copper wire after drawing must be kept bright, not oxidized and discolored, with oil stains, and can be flat and tightly coiled on the take-up reel. We have stepped up to the step of drawing 0.011mm, and the next step is 0.010mm.
