Custom High Quality 0.025-0.100 Ohno Continuous Casting 99.9999% OCC Wire For Audio Products

Thn terms of material characteristics, the biggest feature of single crystal copper is that there are relatively few grain boundaries and it has a columnar crystal structure. This characteristic means that when electrons are conducted in single crystal copper, there is less scattering, resulting in better electrical conductivity. At the same time, the columnar crystal structure also makes single crystal copper better able to withstand deformation when stressed, showing high flexibility.

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.
