Magnesium conversion coating improves corrosion resistance, paint adhesion, and surface protection for magnesium components.
Custom Coating Inc. provides chemical conversion coating for magnesium components using dedicated processing equipment designed specifically for magnesium applications. Magnesium cannot be processed in the same conversion coating baths used for aluminum. Our facility maintains dedicated magnesium cleaning and conversion-coating baths, allowing us to process magnesium components without cross-contamination from our aluminum conversion coating operations.
With large production tanks, established process controls, and experience supporting automotive production and PPAP requirements, Custom Coating can support both ongoing production programs and new magnesium coating opportunities.
Dedicated Magnesium Processing Capability
Our magnesium process includes dedicated:
- 2,500-gallon magnesium cleaning bath
- 2,500-gallon magnesium conversion bath
- Controlled chemical additions and bath monitoring
- Process testing and quality verification
- Production lot traceability
- Automotive PPAP support
- ISO 9001 quality-system controls
Maintaining a dedicated process allows Custom Coating to properly control the chemistry required for magnesium while keeping the process separate from our aluminum conversion coating operation.
Magnesium Conversion Coating Applications
Chemical conversion coatings can be used on magnesium components to provide a suitable surface for applications requiring corrosion protection, paint or coating adhesion, and controlled surface preparation.
We can evaluate magnesium components used in applications such as:
- Automotive components
- Magnesium die castings
- Housings and covers
- Manifolds
- Structural components
- Machined magnesium parts
- Industrial components
- Production and service parts
Because magnesium alloys, customer specifications and end-use requirements vary, all new applications are reviewed before quoting.
Automotive and Production Support
Custom Coating understands the documentation and process discipline required by automotive and industrial customers.
Our team can support:
- PPAP requirements
- Customer-specific processing requirements
- Production part approval
- Lot and process traceability
- Quality documentation
- Ongoing production programs
- New program launches
- Process and specification review
We work with customers during the quoting and approval process to confirm that the coating requirement, part configuration, production volume and packaging expectations are understood before production begins.
Large-Capacity Magnesium Conversion Coating
Additionally, our 2,500-gallon processing tanks enable Custom Coating to handle production-volume magnesium components impractical for smaller finishing operations.
If you are currently sourcing magnesium conversion coating, transferring an existing program, or having difficulty locating a processor with dedicated magnesium capability, contact Custom Coating to discuss your application.
