Bright Acid Tin Plating

Tin plating is no longer offered a ProPlate®


Bright acid Tin plating is a silver-colored, ductile metal whose primary application imparts solderability to otherwise unsolderable base metals. Tin generally has good covering characteristics over a wide range of shapes. Historically Tin has been utilized for its combined corrosion protection and conductivity in avionics radio frequency applications in the aerospace industry. The Tin should be no less than 99.5% pure except where alloyed for particular purposes.

  • Good corrosion resistance
  • Excellent electrical conductivity
  • Excellent thermal conductivity
  • Excellent solderability
  • Poor wear resistance
  • Bright Tin-excellent reflectivity
  • Does not tarnish easily
  • Soft, ductile finish


Tin plating – Bright Acid Tin per Mil-T-10727



  • A bright finish which can serve as a low-cost decorative finish.
  • Tin’s ductility will help prevent galling of base metals in friction contact applications.
