Which material exhibits the worst performance for nozzles based on wear and corrosion characteristics?

Brass exhibits the worst performance for nozzles based on wear and corrosion characteristics due to its composition, which includes copper and zinc. While brass may offer some initial resistance to corrosion, it is generally less durable than other materials, particularly in environments where pesticides and chemicals are used. The chemical nature of many pesticides can lead to accelerated corrosion in brass components, diminishing their lifespan.

In contrast, ceramic materials are known for their exceptional wear resistance and do not corrode easily, making them suitable for high-abrasion applications. Hardened stainless steel is specifically designed to resist wear and offers good corrosion resistance, which contributes to longer-lasting nozzle performance. Regular stainless steel, while more resistant than brass, may not endure as harshly abrasive conditions. Therefore, when it comes to long-term performance in demanding applications, brass falls short compared to the other materials listed.
