Tin plating is an electrolytic process. A dull (or stannate) tin finish is most often used by A Class. 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. A Class offers "Barrel" plating for cost effective treatment of very small connectors or components as well as bath plating for larger components.
Benefits of Tin Plating: 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.
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.
Applications of Tin Plating: Examples include: Low-tech electrical or electronic components such as electronic connectors or bus bars; commercial cooking equipment; parts requiring soldering; other.
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 or copper alloys.
Design Cautions: As this is an electrolytic process it is necessary to use jigging, racking or wiring to provide for electrical current conductivity. Some shapes lend themselves more easily to this than others. In some cases the addition of a sprue or hole is necessary. Please consult your plating adviser prior to finalising design if you intend to use this finishing process.

One of the largest and most diverse surface coating and finishing ‘job shops’ in Australia, A-Class Metal Finishers (A-Class), supports manufacturers and engineering shops across the country with their needs for high quality surface finishing for a range of products and items.
A Class Metal Finishers has capabilities in surface treatments and coatings for many substrate types e.g. steel, alloys, aluminium, brass, stainless, ABS plastics and more. Finishes can include ‘functional’ coatings to provide corrosion resistance, hardness, improved conductivity or surface performance (e.g. tin, electroless nickel, high purity silver & gold plating, chemical cleaning, de-burring, passivation, etc). Decorative coatings / platings are also available (e.g. chrome, gold, nickel, silver, satin finishes, etc). Treatments are provided for many product types including tapware, antennas, tools & dies, hardware, lighting, electrical & electronics, wheels, and many other items. Extensive surface preparation and polishing services also support the high quality outcomes achieved.
