Chromate Conversion Coating

H&W Global Industries offers a chromate and a chromium free, RoHS-compliant chromate conversion coating depending on the needs of the customer. Alodine® and Irridite® are commonly used materials.

Prior to coating, the base metal is mechanically or chemically cleaned to make sure a water break-free surface is obtained after rinsing. Abrasives containing iron such as steel wool, iron oxide, rouge or steel wire are never used for cleaning operations. Treated parts that have become soiled are cleaned with materials that will remove the soil without damaging thebase metal, the part or the conversion coating. If the coating is damaged, the damages are re-cleaned and recoated or the part is rejected upon inspection.

Proven process-control inspections ensure the high level of quality we consistently deliver on our chromate conversion coatings. For more information about our chromate conversion coatings call us at 724-465-6177.
