        1. Product:

          Diamond Wire is a special high strength steel wire with single layer diamond abrasives fixed on its surface. According to the diamond bonding process, it can be divided into Resin bonded diamond Wire(RW),the Electroplated diamond Wire(EW)and Diamond Cable(DC).It has strong cutting capability for sawing large size, super hard and brittle crystalline materials, such as monocrystalline/polycrystalline silicon ,silicon carbide, sapphire, crystal and other precious crystals. Compared with free abrasive sawing wire. The advantages of diamond wire is lower overall processing costs, improvement of processing quality and reduction of environmental influence etc.
