Most manufacturers use an aluminum alloy consisting of aluminum as the base material and another metal such as zinc, tin, magnesium or silicon. The additional metal material enhances the properties of the aluminum and makes the part more amenable to electroplating and other metal finishing techniques.

Plating speed. 0.14 µm/min at 1 A/dm 2) 0.6 µm/min at 3 A/dm 2) Cyanide is a strong complexing agent. For this reason it is often used in the electroplating industry. In the case of copper-tin alloys, the use of cyanide allows and controls the simultaneous deposition to form a compact alloy with excellent properties.

Tin Electroplating is widely used in manufacturing printed circuit boards (PCBs), printed wiring boards (PWBs), electronic components. Most electric circuit connections are made by Soldering therefore the surfaces of the conductors being connected are coated by tin or a tin alloy having excellent solderability. Additionally tin coating protects the components and connections from corrosion in ...
