  • FT-31.8T-3.2A2
  • Material of Piezoelectric Diaphragms:

    Piezo Benders, two position piezoelectric ceramic disks(or three position Piezoelectric Ceramic Chip) substrate materials are also mainly four kinds: copper, stainless steel, nickel alloy and iron.brass material is normal, They can be divided into thick film, ordinary film, thin film and ultra-thin film. Thick sheet refers to metal sheet greater than or equal to 0.3mm or silver sheet greater than or equal to 0.3mm; Ordinary sheet is metal sheet with thickness greater than or equal to 0.2mm and less than 0.3mm, or silver sheet with thickness greater than or equal to 0.2mm and less than 0.3mm; Sheet refers to the thickness of metal sheet less than or equal to 0.1mm and less than 0.2mm, or the thickness of silver sheet greater than or equal to 0.1mm and less than 0.2mm; Ultra thin sheet refers to the thickness of metal sheet is greater than or equal to 0.05mm and less than 0.1mm, or the thickness of silver sheet is greater than or equal to 0.05mm and less than 0.1mm.
