Precision Magnesium Machining Service with PEO + Cerakote Coating for Aerospace & UAV Applications at ±0.05 mm Tolerance

At JYH Precision Machining, we provide high-precision magnesium machining services combined with advanced surface protection solutions such as PEO (Plasma Electrolytic Oxidation) and Cerakote ceramic coating. This powerful surface treatment combination significantly improves magnesium's corrosion resistance, wear performance, and thermal stability—making it ideal for demanding environments.

From prototype development to low-volume and mass production, we manufacture magnesium components with excellent dimensional accuracy, stable quality, and premium surface finish suitable for aerospace, UAV, robotics, automotive, defense, and high-end electronics industries.

Precision magnesium machining refers to CNC manufacturing of magnesium alloy parts using advanced milling, turning, drilling, and 5-axis machining processes to achieve tight tolerances and complex geometries.

Magnesium is known as the lightest structural metal, offering excellent strength-to-weight ratio, vibration damping, and machinability. However, magnesium requires specialized machining methods and surface protection because it is naturally more reactive than aluminum or stainless steel.

At JYH, we ensure safe and stable magnesium machining through strict process control and finishing expertise.

The product shown is a precision-machined magnesium cover plate featuring:

• Circular profile with tight dimensional accuracy
• Honeycomb ventilation pattern for airflow and lightweight design
• Precision drilled mounting holes
• High-quality surface coating suitable for industrial assembly

This type of magnesium component is commonly used as:

• UAV housing cover
• Aerospace ventilation panel
• Lightweight motor cover
• Electronic equipment enclosure part
• Structural protective lid

Magnesium alloys are increasingly popular for high-performance lightweight applications due to:

• Ultra-lightweight (about 33% lighter than aluminum)
• Excellent machinability (faster cutting speed, lower tool wear)
• Strong stiffness-to-weight ratio
• Superior vibration absorption
• Good thermal conductivity
• Ideal for aerospace and UAV weight reduction

However, magnesium requires proper coating and protection—this is where PEO + Cerakote becomes a premium solution.

PEO is an electrochemical process that creates a thick ceramic oxide layer on magnesium surfaces. It dramatically improves:

• Corrosion resistance
• Wear resistance
• Hardness
• Adhesion strength for top coatings

Cerakote is a high-performance ceramic-polymer coating applied over PEO to provide:

• Enhanced corrosion sealing
• Premium appearance (custom colors available)
• Chemical resistance
• UV resistance
• Improved surface smoothness

PEO provides a strong ceramic base layer, while Cerakote seals pores and improves appearance and corrosion resistance. Together they deliver one of the best surface solutions available for magnesium.
