- Electronics and HVAC: Their thermal conductivity makes aluminum square tubes suitable for heat sinks and ventilation structures.
The manufacturing of aluminum square tubes involves several critical steps to ensure product quality and performance:
- Extrusion: Aluminum billets are heated and forced through a die to create the square tube profile. This process allows for precise control over dimensions and wall thickness.
- Heat Treatment: Post-extrusion heat treatments such as annealing or T6 tempering improve mechanical properties like strength and ductility.
- Surface Finishing: Anodizing, powder coating, or polishing enhances corrosion resistance and aesthetics.
- Cutting and Fabrication: Tubes are cut to length and may undergo additional fabrication like drilling, bending, or welding based on customer requirements.
- Quality Inspection: Dimensional checks, tensile testing, and surface inspections ensure compliance with international standards and customer specifications.
