This aluminum rectangular metal part is manufactured through high-precision CNC numerical control milling. It is specifically designed for industrial machinery, automation equipment and precision instruments. Each part undergoes precise processing, with strict control over the hole positions, inner diameters and overall dimensions, ensuring that it meets the ±0.01mm high precision tolerance requirements, achieving perfect installation fit and structural stability. The square design combined with precise hole layout makes the part more stable and reliable in mechanical assembly. 

The surface is treated with high-quality black oxidation, forming a uniform and dense oxide film. This treatment not only enhances the corrosion resistance and wear resistance of the parts, but also improves the overall appearance and enhances the industrial aesthetic appeal. The black oxidized surface remains evenly colored over long-term use, reduces friction and wear, and provides a lasting guarantee for high-frequency mechanical operations. 

Aluminum materials are inherently lightweight and have high strength, enabling the components to maintain robustness and reliability while helping to reduce the overall load of the mechanical structure and optimize equipment performance. The combination of CNC milling and black oxide treatment not only ensures accuracy and durability but also provides an economically viable solution for industrial design. 

This product offers flexible customization services. Buyers can customize it according to specific installation requirements, hole size and thickness specifications.
