Which material is recommended to prevent nozzle wear by resisting erosion?

• A. Stainless steel
• B. Plastic
• C. Brass
• D. Aluminum

Answer: (A)

Erosion resistance in nozzle components hinges on using a material with high hardness and good wear durability. When water carries sand or other particles at high speed, the tiny orifice and surrounding surfaces experience abrasive wear. A material like stainless steel stands up better to that abrasion than softer metals or plastics, helping the nozzle retain its precise orifice size and spray pattern longer. Plastic, brass, and aluminum are softer and wear more quickly under abrasive flow, leading to changes in flow, droplet size, and distribution. Stainless steel combines hardness with good corrosion resistance, making it the most durable choice for preventing nozzle wear in typical irrigation conditions.
