How to choose the material of sandblasting nozzles 

-Nozzle Material Guide

All sandblasting abrasive nozzles have their limited life spans. Maybe you want to choose the cheapest option, while it may not always be the best option. But what nozzle material delivers the best bang for your buck? In order to make you know more clear about different material nozzles, today we put together the Nozzle Material Guide here for your reference, which may help answer that question.

There are four types of material that are used most in abrasive blasting nozzles: Ceramic, Tungsten Carbide, Silicon Carbide, and Boron Carbide.

Ceramic Nozzles

Ceramic nozzles have been the main material of nozzles in the blasting industry since the beginning. They perform well with softer abrasives but, inevitably wear out quicker with nowadays advanced abrasives. In fact, you’ll go through approximately 100 ceramic nozzles in the same time frame as seven tungsten carbide nozzles (or silicon carbide nozzles) or a single boron-carbide nozzle. At BSTEC, we want to provide our customers with quality materials for all sandblasting projects. For this reason, we don’t produce ceramic nozzles by ourselves. But some customers only like ceramic nozzles, we can also get the ceramic nozzles as you need upon request. 

Tungsten Carbide Nozzles

Tungsten Carbide nozzles are very popular in today’s abrasive blasting marketing. These nozzles are much harder than the traditional ceramic nozzles and are a great choice for harder cutting and more aggressive abrasives such as coal slag or other mineral abrasives.  

Silicon Carbide Nozzles

Silicon carbide nozzles offer service life and durability similar to tungsten carbide, but are only about one-third the weight of tungsten carbide nozzles.  BSTEC’s silicon carbide nozzles are an excellent choice when operators are on the job for long periods and prefer a lightweight nozzle. Remember, a happy operator is a productive operator.

Boron Carbide Nozzles

Boron carbide nozzles are the longest wearing of all the commonly-used nozzles. Many can be put off by the higher initial price for boron-carbide nozzles. But, while these nozzles can outlast a tungsten carbide nozzle seven times over, they don’t cost the same as seven tungsten carbide nozzles. In fact, the pricing level isn’t even close to that. This makes boron carbide nozzles the economical choice for most applications.  You’ll also want it when blasting with silicon carbide or aluminum oxide.
