Which nozzle materials are most abrasion-resistant?

Which nozzle materials are most abrasion-resistant?

• A. Brass
• B. Plastic
• C. Tungsten carbide and stainless steel
• D. Aluminum

Answer: (C)

Abrasion resistance is about how well a nozzle resists wear from particles in the spray stream. When liquids carry grit, fertilizer salts, or other solids, the inner surfaces of a nozzle are polished away by friction. Materials that are very hard and tough will keep their shape and flow characteristics longer under that wear. Tungsten carbide and stainless steel are known for this durability. Tungsten carbide is extremely hard, so it resists abrasive erosion very well, which is why carbide tips are common on nozzles used in demanding, abrasive spraying. Stainless steel adds strong wear resistance plus corrosion resistance, helping the nozzle withstand chemicals and harsh environments. In contrast, brass, aluminum, and plastic are softer and wear more quickly under abrasive spray conditions, leading to changes in spray pattern and flow over time. So, the materials that offer the best abrasion resistance are tungsten carbide and stainless steel.
