Product Description
High-Precision CNC Machined Magnesium Housing with Dual PEO & Cerakote Surface Treatment
Engineered for weight-critical applications requiring exceptional structural integrity, this custom-machined magnesium alloy housing delivers maximum strength-to-weight performance. Utilizing multi-axis CNC milling, the component features complex thin-wall geometries, precision mounting lugs, and a centered hexagonal perforation grid designed for optimal ventilation and EMI shield balance.
To overcome the natural susceptibility of magnesium alloys (AZ91D / AZ31B) to environmental oxidation, this component undergoes an advanced dual-layer surface treatment process:
- Plasma Electrolytic Oxidation (PEO) Base layer: Creates a dense, ceramic oxide layer deep within the substrate, providing superior corrosion resistance, dielectric breakdown strength, and wear durability.
- Cerakote Ceramic Finish Topcoat: A thin-film thermal ceramic coating applied over the PEO layer to deliver a non-reflective matte aesthetic, enhanced chemical protection, and UV resistance without compromising tight mechanical tolerances.
Key Technical Specifications

Surface Treatment Performance Advantage
- Corrosion Protection: PEO layer blocks salt spray degradation, exceeding standard anodizing limits on magnesium.
- Thermal Stability: Cerakote topcoat withstands elevated operating temperatures while maintaining color stability and mechanical protection.
- Weight-to-Strength Optimization: Magnesium provides a ~33% weight reduction over standard 6061 aluminum while maintaining rigidity.
- Precision Fitting: Micro-thin coating deposition keeps tight bore tolerances, threaded holes, and mounting bosses within spec without post-coating re-machining.
