Plating and Coatings

Chemical Matte Black Coatings

Our specialist PX-3 chemical blacking process gives our products a durable matte black finish, while retaining all the precision, tensile strength, and corrosion-resistant properties of a standard Stainless Steel component.

What is PX-3 Chemical Blacking?

Chemical blacking essentially involves embedding a black chemical pigment into the outermost layer of the chosen component. The result is that the integrity and accuracy of our components is not altered by this process. Similar finishes such as painting and plating add a solid layer to the outside of a product, which will negatively affect both the precise dimensions and surface texture of a part.

Non-Reflective Properties

AccuGroup’s PX-3 chemical black coating process gives components a non-reflective overlay to prevent glare and reduce component visibility. Our chemical blacking is ideal for use on automotive, aeronautical and aerospace applications, where reflective glare can be highly dangerous. Our PX-3 coatings have even been utilised for military stealth projects.

Can my Product be Chemically Blacked?

almost all Stainless Steel Precision Screws and most other Stainless Steel products within the AccuGroup range can be chemically blacked on request. If chemical blacking is not listed as a standard finish on any of our products, please contact our sales team for pricing.

Lead Times

Please note: the preparation and processing of AccuGroup's PX-3 chemical blackening procedure can add 10 working days to the lead time of a product if the blackened version of a component is not held in stock.
