Saw Wire

Saw wire, ranging from 70 to 200 μm in diameter, is brass coated high tensile high carbon steel wire and used in cutting process with wire saw machines that is essential process for cutting solar cells, silicon ingot slicing to obtain semiconductor wafers and cutting quartz crystals. Saw wire is required some characteristics; i.e. smaller change in wire cast between before and after used is one of them, so that higher cutting performance is obtained. At the same time, the request for smaller diameter with higher tensile strength wire is increasing in order to reduce kerf loss. To meet theses demands, we apply the technologies, which are established through the piano wire and steel cord manufacturing, to saw wire.
