Bright Nickel Plating Ideal as an ornamental finish for sales appeal where cost is a predominating factor.
Electroless Nickel Assures absolute uniformity of plate inside and our regardless or irregularities of shape.
Sulfamate Nickel Ideal for aircraft and nuclear applications but has many industrial applications.
Tin Used on items that come in contact with foods or in electrical field.
Lead, Tin, Alloy, or Solder Plate Applied to parts that have to be soldered after assembly.
Surface Treatments
Yellow and Clear Chromate This coating provides a better bond and more durable protection for paint than more expensive oxide forming processes on aluminum and it's alloys.
Iridate #14-2 A chemical process clear to yellow corrosion resistant films on aluminum and it's alloys.
Conversion Coatings A finish for zinc (clear, blue, yellow, olive drab or black), aluminum, copper, brass and bronze, which protects against corrosion.
Pickling & Passivating On Stainless Steel This is a process that remobes all foreign material from the surface of stainless steel.
Black Oxide This is a jet-black decorative finish for iron and steel. Has some corrosion inhibiting properties in it but is usually supplemented by rust preventive oil. No dimensional change.
Titamium Cleaning & Acid Etching This is and Aerospace requirement from the OEMs like GEAE for P4TF3.
Anodizing
Sulfuric Acid Provides thick oxide coatings for aluminum and its alloys.
Color Anodizing F.M. Callahan & Son, Inc. are experts at dying anodized coatings with pleasing colors.
