Aluminium Alloy 6063 is a widely used extrusion alloy renowned for its excellent extrudability, corrosion resistance, and versatility in various applications. It belongs to the 6000 series of aluminum alloys, known for their balance of strength, formability, and surface finish. Here is a detailed description covering its composition, properties, and common applications:
Composition:
Aluminum (Al): Makes up around 98.9% of the alloy, providing the primary element.
Silicon (Si): Typically between 0.20–0.60%: Enhances the alloy's strength and facilitates extrusion.
Copper (Cu): Usually less than 0.10%: Helps in improving corrosion resistance.
Manganese (Mn): Generally less than 0.10%: Aids in controlling grain structure and improving strength.
Magnesium (Mg): Ranges around 0.45–0.90%: Contributes to the alloy's strength and workability.
Zinc (Zn): Usually less than 0.10%: Acts as a minor alloying element.
Properties:
Extrudability: Excellent extrusion characteristics, allowing it to be formed into complex shapes with tight tolerances.
Corrosion Resistance: Offers good resistance to corrosion, making it suitable for outdoor applications.
Surface Finish: Achieves a smooth and aesthetically pleasing surface when anodized or treated.
Strength: Provides decent strength for structural applications, especially after heat treatment.
Machinability: Exhibits good machinability in the tempered condition.
Weldability: Demonstrates good weldability using various techniques.
Heat Treatment:
Aluminium Alloy 6063 can be heat-treated to improve its mechanical properties, primarily by applying precipitation hardening (aging) treatments.
Common Applications:
6063 aluminum alloy is used in various industries due to its favorable properties, including:
Architectural Applications: Window and door frames, curtain walls, and other architectural extrusions.
Automotive Parts: Body trim, interior components, and structural elements.
