The treatment of α Alpha copper from Furutech OCC drivers is favored by Furutech engineers to excel in sound reproduction.

The α (Alpha) OCC treatment is done with high purity oxygen-free copper using a particular technological cooling process at very low temperature.

Unlike OFC cables, virtually all impurities are removed at the micron using a special Furutech single casting process.
