Cadmium Plating (Electroplating)

Cadmium plating is an attractive, soft coating that can be deposited on various base materials, up to and including steels, copper and different types of iron. Moreover, it is one of the few deposits that is sacrificial, excelling in corrosion protection.

With natural lubricity, Cad plating also provides anti-galling and low friction properties.

Furthermore, other characteristics of Cadmium coating are low chemical resistance, ease of solderability and the flexibility to coat on dissimilar materials. Also, due to the efficiency of the bath, Cadmium is an excellent solution for the coating of critical parts as well as complex geometries.

Benefits of Cadmium Plating:

Good protection against corrosion in salt atmospheres and at low thickness

Resistant to mold and bacteria growth

Low electrical resistance and exceptional conductivity

Favorable galvanic compatibility with aluminum

Natural lubricity providing anti-galling and low-friction properties

Superior solderability

Creates a good bonding surface for adhesives

Works well as a paint base

Can be used on differing substrates such as steel, iron, copper, brass and aluminum

Galvanic protection for iron and steel substrates that can provide corrosion protection even when scratched

Soft and Malleable

Chromates available in Black, Clear, Olive Drab and Yellow

Cad Plating Properties:​

THICKNESS PER CLASS:

I – 0.0005″ minimum

II – 0.0003″ minimum

III – 0.0002″ minimum

PLATING TYPES:

Type I. Also called “as plated,” this type of plating serves as cadmium electroplating’s default color scheme, meaning no additional color treatment is applied.

Type II. This type of cadmium plated is iridescent yellow colored. The quality of type II treatment is tested by using a salt spray on the exterior of the plated component, then checking for signs of corrosion after a 96-hour waiting period.

Type III. This type of cadmium plating has a phosphate supplementary colorization and is usually employed as a paint base.
