Super thin 0.05mm 2UEW 155/180 enamel magnetic copper winding wire

The selection of copper wire as raw materials and the process of drawing play a key role in fine wire drawing.

With the 0.80mm copper wire drawn to 0.011mm, it has to go through several procedures such as middle draw and annealing, small draw and anealing, fine draw and micro drawing with annealing,

In order to ensure the softness of wire, copper wire needs to be annealed every time when its cross section is compressed by 90%. Copper wire after drawing must keep bright, oxidation, discoloration and enamel stains must be avoided.

Besides, the copper wire needs to be winded orderly and tightly on the take-up spool. We made a breakthrough in drawing 0.011mm fine enameled wire, and now we decidedly set our goal for 0.010mm.

RUIYUAN was established in 2002, located in Tianjin City,the second largest port city in China.We have been focusing on different kinds of high quality wires: enameled round copper wire, rectangular enameled copper triple insulated wire, silk covered Litz wire, bonding wire and special enameled wire for 21 years.Ruiyuan is one of the pioneers in producing micro thin enameled wires below 0.03mm in China. Our R & D team has 20 years of market experience. In 2019, our finest diameter is 0.011mm, and mass production has been achieved. All of our products are UL, RoHS certified, in line with industry standards IEC60317, JIS C 3202, NEMA, NW82.
