1. What is a Large Diameter Aluminum Rod?

Large diameter aluminum rods typically refer to rods with a diameter over 100mm. These rods are widely used in aerospace, automotive manufacturing, mechanical processing, and construction due to their lightweight, high strength, and excellent corrosion resistance. Advanced production techniques allow for various surface and heat treatments to meet diverse industrial demands.

2. Features of Large Diameter Aluminum Rods

• Lightweight and High Strength: One-third the density of steel, with strength comparable to some steels after treatment.
• Strong Corrosion Resistance: Natural oxide layer improves oxidation resistance.
• Electrical and Thermal Conductivity: 60% of copper's conductivity, much lighter and cost-effective.
• Good Machinability: Easy to cut, weld, and cast for manufacturing processes.

3. Production Process

• Casting: Includes extrusion casting and continuous casting and rolling for stable performance.
• Heat Treatment:
  • Annealing (O condition): Reduces hardness.
  • Quenching (T6, T651): Increases strength and wear resistance.
  • Aging: Enhances mechanical properties.
• Quality Inspection: Complies with ASTM B221, EN AW-6061, ISO 9001, AS9100 standards.

4. Main Application Fields

• Aerospace: Fuselage frames, landing gear, and structural components.
• Automotive: Engine parts, frames, and wheels.
• Machinery: Shafts, fasteners, precision parts.
• Construction: Supports for high-rise structures and solar brackets.
• Electronics and Power: Busbars, heat sinks, and conductors.

5. How to Choose the Right Large Diameter Aluminum Rod?

• Choose the Right Alloy:
  • 6061: Moderate strength, good corrosion resistance – ideal for structural use.
  • 7075: Ultra-high strength – suitable for aerospace and heavy-load areas.
• Surface Treatment: Anodizing for corrosion resistance, coating/electroplating for durability.
• Supplier Selection: Focus on certifications, production scale, and price-performance ratio.
