Xiamen Honglu started the development of tungsten wire with high tensile strength in 2018, and brought independently developed tungsten wire for photovoltaic application into the market in 2021. Xiamen Honglu’s tungsten wire for photovoltaic application is used as the core wire for diamond-coated wire to cut silicon ingot. With its great potential for redrawing to ultrafine sizes, and superior features, including high strength, high ductility, corrosion resistance, and high electric conductivity, it contributes to the development trend of "N-type" and "Thinner" in photovoltaic silicon wafers, and starts to replace the traditional high carbon steel wire. With the rapid development of tungsten wire for photovoltaic application, Xiamen Honglu enters the photovoltaic area and makes our own contribution to the realization of the "dual-carbon" goals.
