•Stainless Steel: Widely used for diaphragm manufacturing due to its excellent corrosion resistance, high strength, and good elasticity, such as grades 304 and 316, which are suitable for applications in food processing, chemical industries, and other settings where pressure switches come into contact with corrosive media.
•Titanium (Ti) and Tantalum (Ta): These rare metals display outstanding corrosion resistance and heat resistance, particularly excelling in extreme conditions. They are favored for pressure switches in marine engineering, aerospace, and environments involving strong acids and bases.
•Monel Alloy: A nickel-copper alloy that demonstrates exceptional corrosion resistance against many aggressive media and possesses good mechanical properties, commonly used for making diaphragms in pressure switches designed to operate in seawater or salt spray environments.
•Copper Alloys: Brass and bronze, for example, are chosen for their good electrical conductivity and mechanical workability, typically used in fabricating internal electrical contacts and housings within pressure switches to ensure reliable circuit opening and closing while providing a degree of protection.
•Aluminum Alloys: Lightweight yet offering satisfactory mechanical strength and corrosion resistance, these are suitable for creating enclosures. They meet structural strength requirements while reducing overall equipment weight, particularly beneficial in mobile devices or space-constrained applications.
For high-temperature, high-pressure, or special medium scenarios, specialized alloys or composite materials might be used, such as Hastelloy (HC and HB), Inconel, etc. These materials can withstand stresses at elevated temperatures and pressures while maintaining good dimensional stability and chemical stability.In summary, the selection of metal materials in the design of pressure switches is critical, directly impacting factors like accuracy, durability, safety, and adaptability to various operating environments. By judiciously choosing metal materials with different characteristics, it becomes possible to tailor highly efficient and dependable pressure switch products for specific industry needs and application requirements.
