Generally, factors such as operating pressure and operating environment (corrosion resistance? high temperature) need to be considered when selecting the nozzle material. From the perspective of the process difficulty and processing cost of the nozzle, the common processing materials are aluminum and copper, and the wear-resistant material is ceramic carbide material formed through chemical reaction and sintering process. Under different spray working conditions, there are always economical and durable material nozzles to meet the needs. If you have any special material requirements, please contact us.
