Hardened tungsten carbide nozzle YG8Z made in China
Tungsten carbide, not to be confounded with tungsten alloy, which is metal, is the ceramic of choice when it comes to wear and abrasion resistance. Cutting tools for steel and tool steel are made from tungsten carbide. It is also used extensively in the mining industry as a button insert for crushing rocks. The high thermal performance of the tungsten carbide keeps the nozzle tip hot, thus allowing faster printing speed without sacrificing the quality. Carbide nozzles and other nozzles: Common nozzle materials include cast iron, ceramic, tungsten carbide, silicon carbide, and boron carbide. Ceramic nozzles are only used in non-aggressive lightweight equipment and abrasives in explosive cabinets. Tungsten, silicon, and boron carbide are the most popular applications for blasting due to their long service life. The comparison between cemented carbide nozzles and other nozzle life is listed below.
