Tin Electroplating

Tin Electroplating Services For Advanced Manufacturers

Tin, a safe and corrosion-resistant material with a whitish-gray appearance, finds extensive use across numerous industries. Its ability to prevent base metals from oxidizing makes tin-plated metals a preferred choice for soldering applications. Remarkably adaptable, tin can be applied to virtually any type of metal substrate.

Tin Electroplating Solutions

  • Bright Tin generally is preferred for electrical contact applications such as bus bars, terminals and switch components not soldered to
  • Matte Tin is preferred f or solderable applications as it is free of the organic additives found in Bright Tin
  • Tin deposits will oxidize over time so storage of the plated components should be considered for extending shelf life. Preplates of other metals, most commonly nickel, are also used as an effective barrier against diffusion and can significantly extend the solderability shelf life of tin plated parts.
  • Because Tin changes structure and loses adhesion when exposed to temperatures below -40 Fahrenheit (-40 Celcius) Tin plating is recommended for low temperature applications

Frequently Asked Questions

About Tin Electroplating

A component of Bronze, use of Tin in metal working dates some 5000 years ago back to -- you guessed it -- the Bronze Age

Tin is a non-toxic and corrosion resistant whitish gray deposit used in a wide variety of industries. Because it protects the base metal from oxidizing Tin-plated metals are commonly used in applications calling for soldering. Highly versatile, tin can be deposited onto more or less any metal substrate

Tin whiskers – sharp, microscopic protrusions that can form on the surface of objects plated in pure tin – are electrically conductive and can cause sort circuits in electrical components. As a result, care should be taken in determining whether your particular finishing application is better served by pure tin or one of many available tin alloys.
