Product Description
Ultra-Lightweight Custom Precision CNC Machined Magnesium Alloy Housings
Engineered for weight-critical systems, these custom magnesium CNC machined housings deliver extreme structural efficiency—offering up to 33% weight savings compared to aluminum without sacrificing mechanical strength. Utilizing high-precision 5-axis CNC milling, each housing features complex internal geometry, precise bearing bores, and thin-wall structural integrity.
To eliminate magnesium's inherent susceptibility to galvanic corrosion and environmental degradation, parts undergo a dual-layer surface treatment: Plasma Electrolytic Oxidation (PEO/MAO) produces a dense ceramic base layer for impact resistance, followed by a thin-film Cerakote ceramic topcoat for chemical resistance, UV protection, and a refined matte finish.
Technical Specifications
| Specification Parameter | Technical Detail |
|---|---|
| Base Material | Magnesium Alloy (AZ91D / AZ31B / WE43 - Customizable) |
| Primary Coating (Base Layer) | Plasma Electrolytic Oxidation (PEO / Micro-Arc Oxidation) |
| Secondary Coating (Top Layer) | Advanced Ceramic Cerakote (Matte Gray/Off-White Finish) |
| Dimensional Tolerance | ±0.008 mm to ±0.015 mm (±0.0003") |
| Corrosion Protection | ASTM B117 Neutral Salt Spray Test > 1,000 Hours |
| Primary Applications | EV gearbox enclosures, drone camera gimbals, aerospace avionics housings |
Coating Performance Comparison
| Surface Treatment | Corrosion Resistance | Abrasion/Hardness | Impact Resistance | Thermal Insulation | Weight Impact |
|---|---|---|---|---|---|
| PEO + Cerakote (Dual) | Superior (1000+ hrs) | Extreme (~1500 HV base) | High | High | Negligible |
| Standard Anodizing | Moderate (200-300 hrs) | Moderate (~400 HV) | Low (Chipping Risk) | Low | Negligible |
| Wet Paint Coating | Low to Moderate | Low | Low (Flaking Risk) | Low | Moderate |
Key Design Advantages
- Ultra-Lightweight Architecture: Magnesium provides the highest strength-to-weight ratio among structural metals, reducing overall assembly payload.
- Dual-Layer Ceramic Protection: The micro-arc ceramic PEO layer bonds chemically with the magnesium substrate, creating a lock for the protective Cerakote barrier.
- Complex Multi-Axis Geometry: Precision-milled mounting face contours and multi-hole bolt patterns allow for oil-tight, dust-proof sealing.
- Thermal Dissipation & Vibration Damping: Excellent natural dampening capabilities protect internal electronics and gears from high-vibration environments.
