Chromate Conversion Processes in Orlando

Chromate conversion is a type of conversion coating used to passivate a number of alloys. Most commonly steel, aluminum, zinc, cadmium, copper, silver, magnesium, and tin alloys benefit from this process. It is primarily used as a corrosion inhibitor, paint or other finish primer, decorative finish, or to retain electrical conductivity. Chromate conversion is also referred to as Chemical Film, Chem Film, Alodine or Iridite.

Chromate Conversion chemically converts the surface properties of the metal (typically aluminum or magnesium) as opposed to plating which applies a coating onto the surface. With Chromate, there is little to no measurable buildup on the parts. It provides corrosion protection, an excellent bonding surface and low electrical resistance. There are many other benefits.

Fun Fact

Chromating is often performed on galvanized parts to make them more durable. The chromate coating acts as paint does, protecting the zinc from white corrosion, thus making the part considerably more durable, depending on the chromate layer’s thickness.

Did You Know?

Chromate conversion coatings are commonly applied to everyday items such as hardware and tools, and can usually be recognized by their distinctively iridescent, greenish-yellow color. Because aluminum chromate conversion coatings have a gel-like composition, parts that get scratched have a unique self-healing characteristic.  Metal exposed from a scratch slowly becomes covered by soluble chromate from areas adjacent to the scratch.

A.M. Metal Finishing offers Class 1A or Class 3 Chromate Conversion. Processes use Alodine, Iridite, NCP Iridite or Chem-Film. Non-chrome conversion is also available. We are RoHS compliant. Contact us at 407-843-0182 if you need guidance in regard to Chromate Conversion in Central Florida.
