0.025mm 6N/7N High-purity Super Fine Insulated/Bare OCC Copper Wire for Audio

At present, the entire industry is facing the problem that it is difficult to directly confirm single crystal copper. But we can increase the basis for judging single crystal copper through specific production equipment and processes. For example, copper materials produced by vacuum single crystal melting furnaces can largely ensure that they have a single crystal structure. Because this kind of equipment can provide specific conditions for the growth of single crystal copper, which is conducive to the formation of columnar crystals and the reduction of grain boundaries.

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.
