Zinc Phosphate

Zinc Phosphate is a corrosion resistant primer added prior to painting or powder coating on most steel parts that creates a gray appearance on the steel. The coating is porous, helps to reduce galling, and provides a base for paints or powder coating to adhere to. This process is a lighter alternative to manganese phosphate.

MIL-STD-171

Parts that will not be painted can be dipped in oil for longer corrosion resistance. The oil should be specified by our customers prior to running the parts.

A chromate sealer is also provided and is recommended when corrosion resistance is a top priority. The seal or oil should be specified by our customers prior to running the parts.  Note: If the sealer is requested, the parts will no longer be RoHS compliant.

If you do not see a certain spec or standard listed here that your part needs to meet please contact us. Even if it is not listed here we may still be able to meet your requirements!
