Which material is least preferred for making nozzles due to its susceptibility to wear?

The most suitable answer is plastic, as it is typically the least preferred material for making nozzles primarily due to its vulnerability to wear and degradation over time. Nozzles are subjected to high pressures and can experience friction and abrasion from the materials they disperse, such as water, pesticides, or fertilizers. Plastic, while lightweight and cost-effective, does not possess the same durability and resistance to wear as metals.

Bronze, steel, and stainless steel are generally more resilient and better suited for nozzle construction because they can withstand the mechanical stress, temperature variations, and chemical exposure without degrading as quickly as plastic. These metals have higher tensile strengths and are less likely to wear down, crack, or deform, making them more reliable choices for long-term use in landscape maintenance applications. While they may be heavier or more expensive than plastic, their durability significantly outweighs these concerns in contexts where wear resistance is critical.
