Aluminum Processing Parts and Castings
Aluminum machining parts are high-precision components manufactured using CNC milling, turning, and drilling processes from aerospace-grade aluminum alloys. Key features include:
- Lightweight yet high-strength:Superior strength-to-weight ratio compared to steel, ideal for weight-sensitive applications.
- Thermal conductivity:Efficient heat dissipation, making them ideal for heat sinks and electronic housings.
- Corrosion resistance:Natural oxide layer formation enhances durability; further improved via surface treatments.
- CorrosionDesign flexibility:Capable of producing complex geometries, thin walls, and fine surface finishes with tight tolerances.

Surface Treatment
- Anodizing (Type II & III) ：Electrochemical process forming a hard, porous oxide layer (5–25 μm).
- Sand Blasting ：Creates uniform matte finish; improves adhesion for coatings.
- Powder Coating ：Thermosetting polymer applied electrostatically and cured under heat.
- Electropolishing：Electrochemical removal of surface micro-irregularities.
- Nickel Plating / Chrome Plating： For enhanced wear resistance and electrical conductivity.
