What are aluminum profiles？
Aluminum profiles (also known as aluminum extrusions) are long, strip-shaped profiles with specific cross-sectional shapes and dimensions, made from aluminum alloys through an extrusion process. They are a very common building and industrial material.
Basic Concepts
Raw Materials: Typically, aluminum alloys such as 6063, 6061, 6005, and 6082 are used, offering lightweight, corrosion-resistant, and moderately strong characteristics.
Processing: The aluminum bar is heated → extruded into the desired cross-section → cooled → aged → surface treated (anodizing, electrophoresis, spray coating, wood grain transfer, etc.).
Shapes: Available in square tubes, round tubes, angles, channels, I-beams, T-profiles, and special-shaped profiles.
1. Lightweight and High-Strength: With a density approximately one-third that of steel, it offers sufficient strength while being lightweight.
2. High Corrosion Resistance: A dense oxide film forms on the surface, offering weather and moisture resistance.
3. High Plasticity: Complex cross-sections can be achieved through extrusion, making it suitable for customization.
4. High Decorative Properties: After anodizing or spraying, the surface can be created in a variety of colors with a high quality finish.
5. Environmentally Friendly and Recyclable: Aluminum has a high recycling rate.

How to classify aluminum building materials by alloy grade？
Aluminum alloy grades are typically designated according to international standards (such as AA/ASTM, GB/T, and EN), with the 1XXX–7XXX series being the most common. The properties and applications of aluminum alloys within different series vary significantly.
1. 1XXX Series (Industrial Pure Aluminum)
Representative grades: 1100, 1350
Features: High purity (aluminum content ≥99%), good corrosion resistance, and high ductility, but relatively low strength.
Applications: Chemical equipment, food industry, decorative panels.
2. 2XXX Series (Aluminum-Copper Alloy)
Representative grade: 2024
Features: High strength, but poor corrosion resistance, often requiring surface treatment.
Applications: Aerospace structural components, automotive parts.
3. 3XXX Series (Aluminum-Manganese Alloy)
Representative grades: 3003, 3105
Features: Excellent corrosion resistance, good formability, and slightly higher strength than pure aluminum.
Applications: Roofing, wall panels, beverage cans, insulation boards.
4. 4XXX Series (Aluminum-Silicon Alloy)
Representative Grade: 4032
Features: Wear resistance, high temperature resistance, low thermal expansion coefficient.
Applications: Engine parts, automotive engine pistons.
5. 5XXX Series (Aluminum-Magnesium Alloy)
Representative Grades: 5052, 5754, 5083
Features: Strong corrosion resistance (especially in seawater and humid environments), medium strength, and good weldability.
Applications: Shipbuilding, marine engineering, transportation, architectural decoration.
6. 6XXX Series (Aluminum-Magnesium-Silicon Alloy) → Mainstay of architectural and industrial aluminum profiles
Representative Grades: 6061, 6063, 6082
Features: Excellent overall performance, corrosion resistance, moderate strength, heat treatability, and excellent surface treatment properties.
Applications: Architectural profiles (doors, windows, curtain walls), industrial profiles (equipment frames, assembly lines), automotive parts.
6063-T5/T6 is currently the most commonly exported grade for architectural curtain walls, doors, and windows.
7. 7XXX Series (Aluminum-Zinc-Magnesium Alloy)
Representative grades: 7075, 7475
Features: One of the strongest aluminum alloys, but with poor corrosion resistance and high price.
Applications: Aerospace, high-strength structural parts.
Commonly used in architectural decoration: 6063, 6061, 6082 (6 series).
What are the characteristics of 6063-T5/T6 aluminum profiles?
6063-T5/T6 are popular aluminum alloy profiles for architectural and decorative applications, widely used in the Middle East, Europe, the US, and China. Their characteristics are primarily reflected in two dimensions: alloy properties and heat treatment.
Ⅰ. Basic characteristics of 6063 aluminum alloy
6063 belongs to the Al-Mg-Si series (6xxx series). Its core advantage lies in its balanced corrosion resistance, processability, and surface treatment properties.
Chemical Composition (Typical Range):
Silicon (Si): 0.2–0.6%
Magnesium (Mg): 0.45–0.9%
Iron (Fe): ≤0.35%
Aluminum (Al): Balance
Alloy Characteristics:
1. Strong Corrosion Resistance → Suitable for humid and salt-spray environments (such as the coastal areas of the Middle East).
2. Good Extrudability → Suitable for complex cross-sections (window frames, curtain wall keels, and special profiles).
3. Excellent Surface Treatment → Anodizing, electrophoresis, and powder coating enhance decorative properties and durability.
4. Medium Strength → Stronger than 1/3 series aluminum, yet softer than 2/7 series, suitable for medium-strength applications such as doors, windows, and curtain walls.
🟩 Ⅱ. The difference between T5 and T6
T5 / T6″ indicates the heat treatment state, that is, the cooling and aging treatment of the material after extrusion.

T5: More decorative and lightly loaded → Moderate strength, suitable for doors, windows, and lightweight frames.
T6: More load-bearing and durable → Higher strength, commonly used in curtain wall main frames and long-span structures.
🟨 Ⅲ. Comparison of mechanical properties (typical values, unit: MPa)
6063-T5/T6 are popular aluminum alloy profiles for architectural and decorative applications, widely used in the Middle East, Europe, the US, and China. Their characteristics are primarily reflected in two dimensions: alloy properties and heat treatment.

T6 is approximately 30–40% stronger than T5;
However, the ductility (toughness) of the two is similar.
Applications of Aluminium Profiles (T5 vs T6)
T5 Aluminium Profiles – For Doors & Windows
Medium strength, good toughness.
Widely used in sliding doors, folding doors, casement windows, and interior applications.
Best for residential projects, villas, apartments, and offices.
T6 Aluminium Profiles – For Curtain Walls & Engineering Projects
Higher strength and hardness.
Suitable for curtain wall systems, sunrooms, large-span windows/doors.
Commonly used in commercial buildings, hotels, high-rise projects.
T6 is stronger than T5 and is suitable for curtain wall load-bearing; T5 is more suitable for doors, windows and decoration.
