Carefully observe the various processes of aluminum electroplating
When choosing the best aluminum plating process for your manufacturing operation, the two main factors to consider are desired results and cost:

Tin: Tin is a relatively cheap metal that minimizes aluminum alloy plating costs. Tin is often used to plate aluminum electronic components due to its ability to conduct electricity and resist corrosion. Tin finishes can range from matte to glossy.
Nickel: Although aluminum has a high strength-to-weight ratio, it is softer than many other metals. A nickel-plated coating increases the hardness of the aluminum alloy substrate and increases corrosion resistance.
Silver: The energy and power distribution industries rely on silver plating on aluminum to improve corrosion protection and surface conductivity. Silver also provides good lubricity and solderability.
Gold: While gold plating on aluminum is a somewhat expensive process, in most cases it does not form an oxide on the surface of the substrate. Gold's biocompatibility makes it an excellent choice for anodizing aluminum alloys for medical devices.
Electroless Nickel: Electroless nickel coatings provide excellent corrosion resistance and improve the lubricity, hardness and wear resistance of aluminum substrates. Electroless nickel can also be used as an undercoat to enhance and promote adhesion to other plated metals.
