Aluminum Tube

Aluminum Tube Factory Direct | 6061/6063/5052/3003 Aluminum tubes are divided into seamless aluminum tubes and welded aluminum tubes.
Brief Overview
Aluminum tubes (also known as aluminum pipes) are extruded/welded hollow profiles available in round, square, rectangular and special shapes, crafted from high-quality aluminum alloys (6xxx/5xxx/3xxx series). Characterized by lightweight, high precision, excellent corrosion resistance, superior machinability and strong mechanical properties, they are core components for global industries including construction, automotive, aerospace, machinery and electronics. We offer factory-direct pricing, full-spec customization (size/alloy/shape/surface finish), sufficient stock and one-stop global supply, adhering to international standards (ASTM/ISO) to meet diverse overseas procurement demands.
Core Specifications (Mainstream Alloys & Types)

Key Advantages of Aluminum Tube
1. Superior Performance & Precision
- High precision manufacturing: Advanced extrusion and welding technology ensure strict control of outer diameter, wall thickness and length tolerance (±0.008-0.02mm), guaranteeing consistent quality for bulk orders.
- Lightweight & high strength: 30% lighter than steel tubes with comparable load-bearing capacity, reducing overall product weight and transportation costs.
- Excellent corrosion resistance: Alloy composition (Mg/Mn) forms a dense oxide film, resisting atmospheric, seawater and mild chemical corrosion, suitable for indoor/outdoor and harsh environments.
2. Alloy Selection Guide - Match Your Application
- 6061 (Most Versatile): Balanced strength, machinability and weldability, ideal for industrial machinery, automotive components, structural frames and precision parts.
- 6063 (Decorative & Architectural): Superior surface finish and anodizing performance, perfect for construction decoration (curtain walls, handrails), door/window frames and decorative tubing.
- 5052 (Anti-Corrosion): Excellent corrosion resistance and formability, suitable for marine components, chemical equipment, outdoor hardware and fluid transport.
- 3003 (Food-Grade & Industrial): Food-safe (FDA certified), good corrosion resistance and ductility, for food processing equipment, heat exchangers and low-pressure fluid pipelines.
3. Full-Customization & Value-Added Services
- Size customization: Support custom outer diameter (6-300mm), wall thickness (0.8-20mm) and length (100mm-6000mm), tailored to specific project requirements.
- Shape customization: Round, square, rectangular and special-shaped tubes available (based on drawings/samples).
- Surface treatment: Optional mill finish, brushed, anodized (clear/black/colorful), powder coating and anti-rust coating, enhancing durability and aesthetic appeal.
- Precision processing: Provide CNC cutting, bending, drilling, threading and welding services, delivering ready-to-install finished products.
4. Factory Direct & Global Efficient Supply
- No middleman markup, competitive wholesale price with bulk order discounts (10-25% off for orders over 1000kg).
- Sufficient stock for standard sizes (OD 10-50mm, WT 1-3mm, T6 temper), 3-7 days fast delivery for in-stock items.
- Custom orders delivered in 10-20 working days, support urgent order arrangement for time-sensitive projects.
