Cadmium plating offers extraordinary bonding surface for adhesives, such as those increasingly used in aeroplane manufacturing, and is the preferred coating for salt-water environments. Additional advantages of cadmium plating include low electrical resistance; outstanding conductivity; superior solderability; favourable galvanic coupling with aluminium aircraft frames; and excellent natural lubricity, which results in prevention of thread galling and a low coefficient of friction. Furthermore, the corrosion products of cadmium are less significant than those of other plated coatings such as zinc. These characteristics are especially useful in applications where components will be repeatedly disassembled and reassembled, such as in the scheduled maintenance of aircraft. The need for cadmium plated screws continues to be critical to the aerospace industry. The toxicity of Cadmium plated screw surfaces ensures they resist mould or bacteria growth.
