Precision CNC Machined Magnesium Alloy Part with PEO & Cerakote Coating and ±0.005 mm Tolerance
This precision CNC-machined magnesium component is manufactured for applications requiring a combination of low weight, high dimensional accuracy, structural performance, and durable surface protection. The complex housing geometry, recessed features, mounting holes, ribs, and precision center bore are produced using advanced CNC machining processes to maintain consistent quality and repeatability.
After machining, the magnesium part receives PEO (Plasma Electrolytic Oxidation) surface treatment, followed by a black Cerakote protective coating. This combination provides enhanced surface protection and a high-quality black appearance while supporting demanding industrial and engineering applications.
JYH Precision Machining provides custom magnesium CNC machining for prototypes, low-volume production, and volume manufacturing, with inspection and quality control throughout the manufacturing process.

*Specific magnesium alloy and mechanical requirements can be customized according to the customer's drawing and application.
Magnesium is an excellent engineering material when weight reduction is a major design requirement. Compared with many conventional metals, magnesium alloys offer a strong strength-to-weight advantage and are particularly suitable for lightweight housings, structural components and precision mechanical parts.
The PEO coating provides a protective ceramic-like surface on magnesium, while Cerakote adds a durable black finish and additional surface protection. Using a controlled multi-stage finishing process helps achieve both the required appearance and functional surface performance.
