High Light	Ultra-Lightweight Magnesium CNC Machined Housing ，Dual-Layer Ceramic Protection Precision Magnesium Housing ，±0.005 mm Precision Magnesium Alloy Housing

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.
