Cadmium – (6a, 6b, 7, 8): Bright silvery supplementary treatments for Type II can be golden, iridescent. Corrosion resistance is very good
Black Oxide – (11a, 11b): Black oxide coatings; without supplementary preservative treatment are used when a black surface is required. Limited corrosion protection under mildly corrosive conditions, For decorative purposes or decrease in light reflection.
Chromium Platings – (22): Provides a bright decorative finish; corrosion protection; wear resistance and pleasing appearance.
Chromium Satin – (27): Known as industrial or hard chromium; provides wear and abrasion resistance and incidental corrosion protection of parts as the specified thickness of the plating may afford.
Zinc Plate – (27a, 27b, 27c, 27d, 27e): Electrodeposited zinc coatings applied to iron, steel, stainless steel and brass articles provides protection from corrosion. The service life of zinc coating is a function of its thickness and the type of environment to which it is exposed. Bright or dull finish is acceptable.
Black Zinc – (31): Provides corrosion resistance, decorative, used on steel alloys.
Solder Plate – (28): Provides corrosion protection and solderability.
Black Phosphate – (30): Provides corrosion resistance; also acts as a lubricant.
Chromium Engineering – (24): Engineering chromium is usually applied directly to base metal and is finished by grinding to the specific dimensions.
Black Finish – (32): Is a decorative finish, used on steel alloys.
Lubricant – Solid Film – Heat Cured – Corrosion inhibiting -(34a, 34b): Reduces wear and prevents galling when used in steel alloys.
