With blast nozzles, it is the composition of the liner material that determines its resistance to wear. Tungsten carbide is one of the most commonly used materials because it offers the best value when compared to other materials. Nozzles made from tungsten carbide are among the most r ed and durable and work well with most abrasives. Due to their wear-resistance and impact resistance, tungsten carbide nozzles are best used in harsh work site conditions.
