TIN ELECTRO DEPOSITED PLATING

 

Keystone Tin plating offers excellent solderability and ductility. We have facilities for Tin plating both small and large parts in various sized barrels and racks. Keystone Tin plating has exceptional coverage, exhibits long solderability shelf life and has a relatively pore-free deposit. Corrosion protection is excellent . Tin does not tarnish easily and can serve as a low cost decorative finish, although care must be exercised in subsequent part handling as tin is a soft, ductile finish that can scratch or mar easily. Deposits meet salt spray requirements of Specification MIL-T-10727.

                    
Please note that when Tin plating over zinc or brass  base metals, we recommend a thin strike deposit of copper or nickel under the Tin to prevent zinc migration.

 

Tin Plating Specification

 

  • Specification: MIL-T-10727 type I or ASTM-B-545
  • Tin Plating - Class A,B,C,D & E

 

  •  
    • Class A - Deposit thickness of .0001". Mild service conditions provide corrosion and tarnish resistance.
    • Class B - Deposit of .0002". Moderate exposure conditions usually indoors.
    • Class C - Deposit of .0003"-.0004". Severe exposure conditions, elevated temperature where underlying metal diffusion and intermetalic formation processes are accelerated.
    • Class D - Deposit of .0006"-.0008". Very Severe exposure conditions. For use where coating is subject to abrasion or is exposed to corrosive liquids or atmosphere.
    • Class E - Deposit of .0008"-.001".  Thicker coatings are used for water containers, threaded steel couplings of oil strings, and in seacoast atmospheres.
