TDF Metal Finishing provides chemical film and conversion treatment services from Danvers, Massachusetts. Our capabilities include chromating (also known as chemical film treatment) and black copper oxide treatment, including Ebonol.
Whether your drawing specifies a particular treatment or you need to discuss your finishing requirements, our team can review your material, component details and process specification.
Treatments Matched to Your Component Specification
The right surface treatment depends on the base material, component application, and the finished part's requirements.
When submitting an enquiry, provide the material or alloy designation alongside the specified treatment. Details such as the required appearance, areas to be treated and any subsequent finishing operations help our team understand the complete requirement.
Our Chemical Film and Conversion Treatment Capabilities
Chromating and Chemical Film Treatment
TDF offers chromating, also known as chemical film treatment, for components with specified conversion-coating requirements.
Please include the applicable specification and revision, together with any required type, class or supplementary instructions. Our team can review these details against your base material and component drawing to confirm the available processing options.
Where your project includes particular appearance, electrical contact or subsequent coating requirements, identify these clearly at the enquiry stage. Any restrictions on treatment chemistry should also be provided for review.
Black Copper Oxide Treatment
Our capabilities include black copper oxide treatment, including Ebonol.
For components requiring this finish, please provide the material designation, treatment specification and any appearance requirements. Identify visible surfaces, areas to remain untreated and any additional finishing steps shown on your drawing.
If you are working to an approved sample or a defined visual acceptance standard, let our team know so the expected result can be discussed before processing.
Masking and Selective Treatment
Some components require treatment on selected surfaces while other areas must remain untreated. TDF offers masking as part of its wider metal finishing capabilities.
Mark the areas to be treated and protected clearly on your drawing. Include any critical interfaces, contact surfaces or dimensional requirements so our team can review whether masking is suitable for the requested process.
Process Specifications and Acceptance Requirements
Our specifications page includes references relating to chemical films and black copper oxide treatments.
To help us assess your project, please provide:
• Base material and alloy designation.
• Required treatment.
• Applicable specification and revision.
• Specified type or class, where relevant.
• Drawing notes and masking instructions.
• Appearance and acceptance criteria.
• Any testing or documentation requirements.
Where a drawing includes additional customer requirements, please include these with your enquiry rather than relying on the specification reference alone.
Supporting Your Wider Finishing Requirements
If chemical film or black copper oxide treatment forms part of a broader finishing requirement, share the full processing sequence with our team.
TDF also offers anodizing, metal plating, specialist cleaning and etching, and additional finishing services. Our team can review which of these capabilities are relevant to your component and confirm the work we can undertake.
