Tin & Alloy Platings


Tin & Alloy Plating for coating any metallic substrate material

BRIGHT ACID TIN

Tin and its alloys are light grey-white deposits ranging from dull to bright appearance. Soft, ductile, and good corrosion resistance; offers excellent solderability. Tin should not be used in low temperature applications; its grain structure changes, and loses adhesion at -40°C.

Type I
  • electrodeposited (plated) coatings of tin
Type II
  • hot dipped tin
  • .0001-.00025 for solderability
  • .0002-.0004" prevent galling & seizing
  • .0003" minimum for corrosion protection
  • .0002-0006" prevent forming case during nitriding
TIN-LEAD ALLOY

Tin-lead 60/40, 90/10 and 95/5 alloys are electrodeposited for maximum solderability.
  • Unless otherwise specified, .0003-.0005"
  • For flow-brightened finishes, .0003" minimum
