1. Corrosion resistance: Micro-sprayers are usually used for liquid spraying and atomization, and may be exposed to various chemicals, water quality and corrosive substances under environmental conditions. Therefore, the corrosion resistance of the material is a crucial characteristic. Common corrosion-resistant materials include stainless steel (such as 316 stainless steel), special alloys (such as titanium alloys) and certain high-performance plastics (such as polytetrafluoroethylene PTFE). These materials can effectively resist corrosion, extend the service life of the micro-sprayer and maintain its stable performance.

2. Wear resistance and durability: The nozzles and nozzles of the micro-sprayer are parts that directly contact liquids and gases, so they need to have good wear resistance and long service life. Selecting materials with excellent wear resistance can reduce the wear and replacement frequency of the nozzles and improve the reliability and stability of the micro-sprayer. Commonly used wear-resistant materials include cemented carbide, ceramics and special coating materials.

3. Thermal stability: In high temperature or high pressure spray environments, the materials of the micro-sprayer need to be able to maintain good thermal stability to ensure that there is no deformation or performance degradation due to temperature changes. Selecting materials with good thermal conductivity and stability, such as high-temperature resistant plastics (such as polyetheretherketone PEEK) and high-temperature alloys (such as aluminum alloys), can effectively cope with complex working environment requirements.

4. Fluid compatibility: Different fluids or chemicals have different compatibility requirements for materials. Selecting materials that are compatible with the liquid to be sprayed is a key factor in ensuring the stable operation and extended service life of the micro-sprayer. For example, some specific chemicals may be corrosive or soluble to certain materials, so it is necessary to select compatible materials that have been tested and certified.

5. Processability and cost: The processing performance and cost of materials directly affect the manufacturing cost and production efficiency of micro-sprayers. Selecting materials that are easy to process, moderate in cost and can meet performance requirements can help manufacturers reduce manufacturing costs and improve production efficiency. Reasonable material selection can also reduce scrap rate and processing time, thereby optimizing the production process.

6. Environmental friendliness: With the increase in environmental awareness, the material selection of micro-sprayers should also consider their environmental friendliness. Selecting recyclable materials or low environmental impact materials helps reduce resource consumption and waste emissions, and meets the requirements of modern environmental protection.
