What Are Differences of Tungsten Copper Foils, Sheets and Blocks 182

What do you know about tungsten copper foils, strips, sheets, plates, or blocks? What are their differences? Actually, they are the same product with rectangular shape. To distinguish them, people often call them differently. Foils usually mean plates with thickness less than 0.1mm; strips mean thin and narrow plates; sheets mean plates with 0.1-2.0mm thickness; plates mean 2.0-10.0mm thickness and thickness above 10.0mm will be called blocks. Tungsten copper alloy is a refractory metal alloy of tungsten and copper which…

Why Tungsten Wire Can Be for Photovoltaic Purpose by Replacing Carbon Steel Wire? 230

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,…
