1. Product Overview
Aluminium tube (also known as aluminium pipe) is a hollow long-length metal profile manufactured from high-quality aluminium alloy through extrusion, drawing, rolling, and precision finishing processes. It features a smooth inner and outer surface, uniform wall thickness, high dimensional accuracy, and excellent mechanical properties. As a lightweight, high-performance hollow structural material, it is widely used in construction, industry, transportation, electronics, HVAC, fluid transmission, and many other fields.
2. Material & Production Process
- Main Alloys: 6061, 6063, 3003, 5052, 7075, etc.
- Temper Conditions: T5, T6, O, H112, etc., to meet different strength and processing requirements.
- Production Flow: Aluminium ingot → heating → extrusion / drawing → straightening → cutting → surface treatment → inspection → packaging.
- Features: High precision, stable size, good concentricity, customizable outer diameter, inner diameter, and wall thickness.
3. Key Performance Advantages
- Lightweight & High Strength: Low density, about one-third the weight of steel, with high strength-to-weight ratio for load-bearing and weight reduction.
- Excellent Corrosion Resistance: Natural oxide film and surface treatment provide strong anti-rust, anti-oxidation, and weather resistance, suitable for indoor and outdoor use.
- Good Processability: Easy to cut, drill, bend, weld, tap, and assemble; supports high-precision machining.
- High Thermal & Electrical Conductivity: Widely used in heat dissipation, heat exchangers, and electrical components.
- Smooth Surface & Low Fluid Resistance: Ideal for liquid and gas transmission with clean, stable flow.
- Non-Toxic & Recyclable: Safe for drinking water systems and food-grade applications; 100% recyclable, eco-friendly and energy-saving.
