Due to cadmiums toxic nature, it is strictly prohibited from all food and medical applications.
Cadmium plating offers a unique combination of benefits to many desired parts in our industries from corrosion resistance, ductility, solderability, anti-static and anti-galling characteristics. Where dimensional tolerances must be maintained, such as threaded components, etc., cadmium can be applied in a very thin layer. (Plating thickness ranges of 0.0001 to 0.0015).
Supplementary chromate treatments are recommended and will extend the corrosion resistance values of the cadmium coating. Type I finishes with no supplementary treatment, leaving a silver natural appearance, while Type II chromate conversion leaves an iridescent or gold appearance. Type II conversion also provides a great base for painting or other adhesive materials. Please view our Spec Chart for plating thickness and chromate treatment parameters.

Cadmium’s natural appearance once electroplated is silver in color and can be applied to many substrates. IDP offers cadmium applications to: ferrous materials, iron, copper, brass, and aluminum, and when dull applications are required, we can apply multiple plating operations to individual parts with precision masking. All steel parts having a hardness of Rockwell C40 (180,000 PSI) and higher must be baked at 375 degrees F, plus or minus 25 degrees F for 3 hours minimum after plating.
GENERAL CADMIUM APPLICATIONS
