What is the order of materials for nozzle durability starting from the best?

The answer identifies the order of materials based on their durability for use in nozzles. Starting with ceramic, this material is highly resistant to wear and abrasion due to its hardness, making it the best option for nozzle durability. Following ceramic, hardened stainless steel ranks next. It is known for its strength and resilience, providing a good balance between durability and corrosion resistance.

Stainless steel comes after hardened stainless steel, offering decent durability but not quite as much as hardened variants. Finally, brass, while commonly used due to its machinability and lower cost, offers the least durability compared to the other listed materials.

In summary, the sequence demonstrates an understanding of materials science where hardness and resistance to wear play crucial roles in the selection of nozzle materials for longevity and reliability in pesticide application.
