Overview of Aluminum Alloy 6063

It contains magnesium and silicon as the main alloying elements, resulting in good strength, great weldability, and exceptional extrudability. Compared with 6061, Aluminum 6063 is better for appearance-focused applications, while still maintaining adequate strength for medium-load structural use.

As a leading global aluminum alloy supplier, Huaxiao Metal provides high-quality 6063 aluminum sheets, plates, extrusions, and profiles, custom-fabricated according to client requirements. Our products meet ASTM B221/B210 standards, with guaranteed mechanical properties and fast worldwide delivery.

Aluminum 6063 (AA6063), known as the “architectural alloy,” dominates extrusion-driven industries due to its superior surface finish, corrosion resistance (0.03 mm/year in marine atmospheres per ASTM G67), and thermal conductivity (218 W/m·K). Its primary use is in structural glazing systems (curtain walls, window frames) where precise T5/T6 temper profiles achieve 160-205 MPa yield strength while maintaining anodizability for custom finishes. In transportation, 6063 forms lightweight EV battery enclosures and heat sinks, leveraging its 30% weight savings vs. steel and crash energy absorption (80 kJ/m³).

Frequently Asked Questions (FAQ)

What is the difference between Aluminum 6063 and 6061?

6063 offers better surface finish and extrudability, making it the preferred alloy for decorative and architectural uses. 6061, on the other hand, has higher strength and is more suitable for structural applications. If appearance and anodizing are priorities, 6063 is the better choice.

Yes. 6063 has excellent anodizing properties, allowing for clear, colored, or decorative finishes. It is commonly used for architectural applications where appearance is important.

6063 is widely used for window frames, door frames, railings, pipelines, heat sinks, electrical conduits, marine components, and decorative trims due to its corrosion resistance and attractive finish.

The most common tempers are T5, T6, and T52.

  • T5 – medium strength, good surface finish.

  • T6 – highest strength, suitable for structural applications.

  • T52 – improved toughness, commonly used for architectural profiles.
