Let me introduce you to what photovoltaic diamond wire is
Diamond wire is made by uniformly bonding diamond microparticles onto a base wire with a certain distribution density. The base material is typically high-carbon steel wire or tungsten wire. The primary function of diamond wire is to cut silicon ingots or wafers into thin slices. It was originally used for sapphire cutting and began to be applied in photovoltaics around 2010.
The cutting method of diamond wire involves high-speed grinding motion between the wire and the material being cut. In photovoltaic applications, diamond wire is mainly used for wafer cutting, including truncation and slicing, with a focus on slicing. The cutting performance of diamond wire directly affects the quality of the silicon wafer and the efficiency of the solar cell. Currently, photovoltaics are the largest application market for diamond wire, accounting for more than 90% of the total demand.
Compared to slurry cutting technology, diamond wire cutting has advantages such as higher wafer yield, less cutting wear, faster cutting speed, and less environmental pollution.
As a linear cutting tool, the manufacturing materials of diamond wire mainly include the base wire, diamond microparticles, and nickel. According to the base wire material, diamond wires for photovoltaic use are primarily divided into high-carbon steel wire diamond wire (also known as carbon steel diamond wire or carbon steel wire) and tungsten wire diamond wire (also known as tungsten wire). The former is the dominant product in the diamond wire market.
