When choosing a plastic spray head, you need to keep the nozzle's material composition in mind. Some materials are better suited for high temperatures, while others are less suitable. The environment in which the nozzle is used should also be considered. Another consideration is corrosion resistance. Different materials are resistant to different kinds of corrosion. In addition, you should consider the type of media you'll be spraying. Stainless steel, for example, is an alloy of iron and carbon containing chromium, nickel, molybdenum, and vanadium.
