Aluminium Profile – Comprehensive Product Introduction
1. Product Overview
Aluminium profiles (also called aluminium extrusions) are precision-formed structural components made from high‑grade aluminium alloys via hot extrusion, stretching, cutting, and surface finishing. They feature customizable cross‑sections, consistent dimensions, and exceptional mechanical stability, making them a core lightweight material for modern industry, construction, transportation, and electronics.
2. Core Material & Manufacturing
- Alloy Grades: Mainly 6063, 6061, 6005, 7075, etc., balancing strength, ductility, and corrosion resistance.
- Production Flow: Billet heating → hot extrusion → quenching → stretching & straightening → aging treatment → machining → surface finishing → inspection & packaging.
- Process Advantages: Supports complex cross‑sections, high dimensional accuracy, stable performance, and mass production.
3. Key Performance Advantages
- Lightweight & High Strength: Density ~2.7 g/cm³, about 1/3 of steel; high strength‑to‑weight ratio for load‑bearing and weight‑saving applications.
- Excellent Corrosion Resistance: Natural oxide film plus anodizing / powder coating provides long‑term anti‑rust and weather resistance.
- Superior Thermal & Electrical Conductivity: Ideal for heat sinks, electrical enclosures, and thermal management components.
- High Processability: Easy to cut, drill, mill, weld, and assemble; compatible with T‑slot, fastener, and riveted connections.
- Eco‑friendly & Recyclable: 100% recyclable without performance loss, meeting green building and carbon‑neutrality targets.
- Aesthetic & Durable: Surface finishes include anodizing, powder coating, electrophoretic painting, and polishing for appearance and durability.
4. Common Types & Shapes
- Structural Profiles: Square/rectangular tubes, angle bars, channels, I‑beams, H‑beams for frames and supports.
- Industrial T‑slot Profiles: 2020, 3030, 4040, 4080 series for modular frames, workstations, and automation equipment.
- Architectural Profiles: Windows, doors, curtain walls, railings, and sunshade systems.
- Special Profiles: Heat‑sink profiles, automotive profiles, electrical enclosures, LED housing, and custom cross‑sections.
5. Typical Applications
- Construction: Curtain walls, windows, doors, partitions, railings, and green buildings.
- Industrial Automation: Machine frames, assembly lines, safety guards, and modular workstations.
- Transportation: Automobile body parts, rail components, bicycle frames, and aerospace structures.
- Electronics & Electrical: Heat sinks, inverter housings, LED lighting, and battery components.
- Furniture & Decoration: Table frames, display racks, interior trim, and decorative profiles.
6. Surface Finishes
- Anodizing: Hard, abrasion‑resistant oxide layer; silver, black, champagne, and other colors.
- Powder Coating: Rich colors, strong adhesion, weather resistance for outdoor use.
- Electrophoretic Coating: Smooth, uniform, and corrosion‑resistant finish.
- Polishing / Brushing: Mirror or satin effect for high‑end appearance.
7. Customization Capability
We support custom extrusion dies, cross‑section design, alloy selection, length cutting, machining (drilling, milling, tapping), and surface finishing to meet project‑specific requirements for shape, size, strength, and appearance.
8. Quality Assurance
Our aluminium profiles comply with international standards including GB, EN, ASTM, and JIS. They undergo strict testing for mechanical properties, dimensional accuracy, coating adhesion, and corrosion resistance to ensure stable and reliable performance.
9. Summary
Aluminium profiles integrate lightweight, high strength, corrosion resistance, versatility, and sustainability. They are widely used in construction, industry, automotive, electronics, and daily applications, providing efficient, reliable, and cost‑effective solutions for global customers.
