Why Tungsten Wire Can Be for Photovoltaic Purpose by Replacing Carbon Steel Wire? 216

As one of the core consumables in the silicon wafer cutting process, the cutting effect of diamond wire is mainly affected by factors such as product thickness, busbar performance and cutting method. Generally speaking, the cutting effect is better when the diamond wire is thinner. Nowadays, the most common diamond wire busbar in the photovoltaic industry is high carbon steel wire, according to Chinatungsten Online. However, with the development of silicon wafers in the direction of large size and thinning,…
