Term of the Week: Tungsten Carbide Nozzle

The Term of the Week is a weekly feature where A&E turns to industry experts to define common tools, processes, language, etc. used in the awards, engraving, and personalization industry, including terminology within the business realm. Contact Printwear's digital content editor, Marley Jeranko, if you're interested in contributing and for an opportunity to be featured in our daily eNewsletter. 

A usually dark brown- or gray-colored nozzle used for sandcarving. It is typically made from an alloy of elemental boron and metal that makes it similar to steel, but much harder. The makers of these nozzles list their life span of continuous blasting at about 200-plus hours. Cost of such a nozzle is between $120 and $180 each.
