Understanding cost differences among nozzle materials helps explain why brass is often cited as the least expensive option among metal choices. Plastic bodies are typically the cheapest overall because they’re cheap to mold and use common polymers. Among metals, brass is inexpensive to manufacture and machine, and it provides good corrosion resistance for many spray solutions, which keeps its price lower than those of stainless steel or tungsten carbide. Stainless steel and tungsten carbide, on the other hand, offer superior durability and wear resistance, so they cost more. So, when comparing these four materials, brass is usually the least expensive metal option, though plastic would generally be cheaper if considered.
