Nickel (Bright) Suitable for: All metals Resistance to corrosion depends on thickness, generally good Bright silver in color Good for aesthetically decorative finishing
Passivate Suitable for: Stainless steel Excellent resistance to corrosion No change in color results from finishing No change in dimension of part All surface iron oxides removed Treat with light oil following finishing to prevent rust corrosion A cleaning process rather than a traditional finish
Phosphate Suitable for: Steel Fairly good resistance to corrosion. Good resistance to rusting Gray in color
Pickling Suitable for: All metals No resistance to corrosion No change in color after treating Effective removal of scale, rust or other evidence of corrosion
Silver   Suitable for: All metals Excellent resistance to corrosion Bright silver in color Electrical conductivity: Excellent Good for aesthetic finishing Easy to tarnish Excellent for soldering Lubricity: excellent Excellent for anti-galling
