The alodine process forms an oxide film on the surface of the metal, which provides corrosion protection, improves adhesion for painting, and provides electrical insulation.
Alodine is applied using an electrochemical process and produces a thin, uniform coat that adheres to the substrate and helps protect against damage from UV rays, salt, and other environmental factors.
High machinability and ductility, good strength-to-weight ratio. Aluminum alloys have good strength-to-weight ratio, high thermal and electrical conductivity, low density and natural corrosion resistance.
