Which nozzle material is the least resistant to wear?

Brass is known for its relative softness compared to other materials used in nozzle manufacturing, such as stainless steel or plastic. While brass offers good corrosion resistance and is fairly durable in many applications, it tends to wear down more quickly when exposed to abrasive substances or high-velocity fluid flows. This wear can significantly affect the performance and lifespan of the nozzle.

In contrast, stainless steel is generally much harder and more resistant to wear, making it suitable for applications where durability is essential. Plastic nozzles can be less resistant to wear as well, depending on the type of plastic used, but they are often more suitable for lighter applications. Aluminum, while light and with decent resistance to wear, is still harder and more durable than brass in many contexts. Thus, brass stands out as the least resistant to wear due to its softer composition, making it the correct choice.
