5N 6N Ohno Continuous Cast OCC 99.9999% High Purity Single Crystal Monocrystalline Enameled Copper Wire

The process of drawing has a significant influence on the crystal morphology. If drawing is applied to single crystal copper, a short and thick crystal may be compressed into a long and slender one. For instance, when an 8mm rod is drawn to an extremely small diameter such as a few hundredths of a millimeter, the crystals may experience fragmentation. In an extreme case, a single crystal could break into two, three, or more fragments depending on the drawing parameters. These parameters include the drawing speed and the ratio of the drawing dies. However, even after such fragmentation, the resulting crystals still maintain a columnar shape and continue to extend in a certain direction.

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 23 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.
