Tin and Alloy Platings
 

Tin & Alloy Plating for coating any metallic substrate material

Specifications(Military, Federal, and ASTM)

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

  • .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
