Multi-compond Rare-earth Tungsten electrode
Mainly substitute for radioactive thoriated tungsten electrode and other tungsten electrodes.
Applied for the welding of pipelines and small components, and discontinous welding.
Unlike traditional tungsten powder, Ganzhou Hongfei's rare-earth tungsten powder is made of tungsten bars and downstream products by adding appropriate rare earth elements. Compared with the products made of traditional tungsten powder, it has stronger electronic emission ability and can be widely used in manufacturing welding materials, special light sources, and tungsten products for special powder metallurgy.
As a large manufacturer of electric light source materials in the world, Ganzhou Hongfei, relying on its own advanced equipment and deep processing technology advantages, abandoned the idea of only rough processing in the traditional electrode industry, and extended the application of electrode materials by virtue of its technical advantages. It specially developed rare earth tungsten wires for metal halide lamps, high-voltage gas discharge lamps and other lighting industries, leading the development of fine tungsten wires in this industry.
