Precision Magnesium CNC Machining Service with PEO Coating and ±0.005 mm Tolerance for Aerospace Applications

JYH Precision Machining provides high-precision magnesium CNC machining services with Plasma Electrolytic Oxidation (PEO) coating, delivering lightweight, high-strength components for demanding industries such as aerospace, automotive, robotics, medical devices, defense, UAVs, and industrial automation. Our advanced machining capabilities combined with premium PEO surface treatment significantly improve corrosion resistance, wear resistance, electrical insulation, and service life while maintaining the exceptional weight-saving advantages of magnesium alloys.

With years of experience in manufacturing complex magnesium components, we specialize in producing tight-tolerance custom parts from prototypes to high-volume production. Every component undergoes rigorous quality inspection to ensure outstanding dimensional accuracy, surface integrity, and coating consistency.

Magnesium is one of the lightest structural engineering metals available today. It offers excellent machinability, superior vibration damping, and outstanding strength-to-weight ratio, making it the preferred material for applications where weight reduction is critical.

• Extremely lightweight (approximately 33% lighter than aluminum)
• Excellent machinability with faster cutting speeds
• High dimensional stability
• Outstanding vibration damping
• Excellent thermal conductivity
• High strength-to-weight ratio
• Easy to machine into complex geometries
• Reduced overall product weight
• Improved energy efficiency
• Ideal for aerospace and UAV applications

Plasma Electrolytic Oxidation (PEO), also known as Micro Arc Oxidation (MAO), creates a ceramic-like oxide layer directly bonded to the magnesium substrate. Unlike conventional anodizing, PEO produces an exceptionally hard, durable, and corrosion-resistant surface suitable for harsh environments.

• Superior corrosion protection
• Excellent wear resistance
• Increased surface hardness
• High dielectric insulation
