Brass is considered a poor choice for nozzles primarily due to its poor wear life and susceptibility to corrosion. Over time, exposure to various chemicals, particularly pesticides and herbicides, can lead to the degradation of brass, resulting in a decrease in performance and efficiency of the nozzle. This can manifest in inconsistent spray patterns, clogging issues, and premature failure of the nozzle itself.
Furthermore, the wear that occurs when the nozzle is in use can be significant, especially when dealing with abrasive materials or high-pressure applications. As brass wears down, the orifice size may change, affecting the application rate and uniformity of the spray.
In contrast, other materials such as stainless steel or certain high-grade plastics are often preferred for nozzles as they offer better resistance to corrosion and abrasion, leading to a longer lifespan and more reliable performance under various conditions. Thus, the tendency of brass to corrode and wear out quickly makes it an unsuitable option for this application.
