Which nozzle material best resists abrasion?

• A. Ceramic
• B. Plastic
• C. Brass
• D. Aluminum

Answer: (A)

Abrasion resistance in nozzle materials is about how well the material holds up when gritty particles in the spray rub against the orifice. In agricultural sprays, sand and other solids can wear away the nozzle opening, which changes the droplet size and flow over time. Ceramic is extremely hard, so it wears far more slowly than softer materials. That means a ceramic nozzle maintains its orifice size longer, keeping spray pattern and rate more consistent even with abrasive sprays. Softer options like plastic, brass, or aluminum wear more quickly, leading to changes in flow and droplet size and, consequently, drift and application accuracy. A note: ceramic can be brittle if struck or dropped, but for resisting abrasion, it’s the best choice among these materials.
