Most impact sprinkler heads are primarily made from which material?

Most impact sprinkler heads are primarily made from brass for several reasons that contribute to their performance and durability. Brass is a strong and corrosion-resistant metal, which makes it ideal for outdoor use where exposure to the elements can lead to rust and degradation in other materials. The strength of brass ensures that impact sprinklers can withstand the mechanical stress from the water pressure and the kinetic energy generated when the sprinkler operates.

Additionally, brass has excellent wear resistance, which is crucial for the moving parts of the impact sprinkler. This wear resistance helps maintain a consistent and effective spray pattern over time, leading to efficient irrigation. The weight of brass also contributes to the stability of the sprinkler head, preventing it from being easily knocked over or displaced by wind or debris.

While other materials like plastic or aluminum are used in sprinkler heads for specific benefits, such as lower cost or lighter weight in particular applications, brass remains the preferred choice for robustness and longevity in most widely-used impact sprinklers.
