Tin-zinc alloy plating was introduced in the 1940’s and has maintained a small but important niche in the electroplating industry due to its engineering properties and the superior corrosion resistance it provides in a variety of environments and applications. Typically, tin-zinc alloys contain 70-90% Tin, with the balance being Zinc. While older tin-zinc alloy plating baths were based on cyanide containing electrolytes, our newer technology tin zinc is cyanide free.

Applications

  • Electrical connectors
  • Salt water components
  • Parts that require crimping

Advantages

  • Excellent ductility
  • Excellent solderability (most solders are primarily tin)
  • Excellent conductivity
  • Extremely high corrosion resistance to salt water and sulfur dioxide
  • Maintains high corrosion resistance even after hard crimping and bending
  • Can be safely applied to sensitive electronic components and glass to metal seals with no attack to the glass
  • Replacement for the toxic metal, cadmium
  • Provides good protection on steel when in contact with aluminum

Part Size Capabilities

To handle the wide variation of parts required by our customers, our recipe-driven barrel tin zinc lines are equipped with 48″ X 21″ barrels with varying barrel perforations. Our tin zinc line is computer automated, so all the parameters to successfully plate parts according to your specifications are controlled. All part numbers have individual recipes and are entered using bar codes.
