The material is the primary driver of cost. Tungsten Carbide nozzles are the industry standard for durability and cost-efficiency in abrasive cutting. However, for high-precision or ultra-high-pressure tasks, Ruby or Sapphire orifices are used to ensure a consistent stream, though they are more brittle. For the most demanding industrial applications, Diamond orifices offer the longest lifespan (up to 1,000 hours), which justifies a significantly higher upfront price by reducing machine downtime and maintenance costs.
