What is Tin Plating?
Tin plating is an electrolytic process. Tin plating is primarily for "functional" purposes such as providing a level of protection or corrosion resistance to a range of items. Tin is commonly applied over a preliminary coating of copper or brass.

Colour & Aesthetics
Tin plating has a 'whitish grey' hue and is usually applied without the layer of bright nickel used in decorative coatings - as such tin has a dull, or matt appearance. AAEP can provide bright tin if required.
Examples of Tin Plating include: Low-tech electrical or electronic components such as electronic connectors or bus bars and anti gavling.
Substrates suited to this coating:
Tin can be plated over most metal substrates but commonly is used on lower value substrates such as mild steel, brass or copper alloys.
Stannate Tin plating is a lower cost alternative than some protective coatings. Tin also has a good level of conductivity enhancement properties (as opposed to silver which has higher conductivity) which may be of benefit to manufacturers seeking to enhance this property somewhat without adding too much to the price. Tin has good solderability and is therefore a coating of choice where later soldering of components is required.

The two most common tin plating services are MIL-T-10727 and ASTM B545. AAEP also can certify our tin plating services to ISO 2093 and AMS 2408 as well as most company-specific tin plating specifications. A summary of tin plating services per the MIL and ASTM specs is as follows:
Tin Plating Services to MIL-T-10727
Type I - Electrodeposited. Recommends use of ASTM B545 for electrode posits of tin
Type II - Hot Dipped (AAEP does not offer hot dip services)
- ASTM B545 outlines thicknesses for various service conditions in section 6, paragraph 6.1
- 0.0001-0.00025 inch for tin flashing of articles to be soldered
- 0.0002-0.0004 inch for articles to prevent galling or seizing
- 0.0003 inch minimum for articles generally plated to prevent corrosion of basis metals
- 0.0002-0.0006 inch for articles to prevent formation of case during nitrid ing]
