Why is 6063 aluminum alloy the preferred choice for extruded profiles?

6063 aluminum alloy (an aluminum-magnesium-silicon alloy containing approximately 0.45% magnesium and 0.6% silicon) has become the material of choice for extruded aluminum profiles due to its reliable performance and outstanding cost-effectiveness.

Core Characteristics
Easy Extrusion Forming: Smoothly passes through dies to create complex shapes (window trim, furniture components) with tolerances of ±0.1mm—20% faster than 6061 alloy, shortening production cycles.

Superior Surface Treatment: Suitable for anodizing (outdoor durability exceeding 10 years) or powder coating (UV resistance), making it ideal for visible components.

Balanced Strength: T6 heat treatment delivers approximately 215 MPa tensile strength while being 30% lighter than steel—perfect for shelving, railings, and lightweight structures.

Cost-Effective: Priced below 6061/7075 alloys with scrap rates of just 3-5% (vs. 8-10% for others), highly suitable for mass production.

Core Application Areas
Architecture: Window frames, curtain walls (weather-resistant durability)
Furniture: Chair legs, shelves (lightweight strength for daily use)
DIY Projects: Trim, garden edging (easy to cut and drill)
Light Industry: Tool racks, electrical enclosures (practical and economical).

Material Selection Recommendations
Condition: Choose T5 for indoor use; select T6 for outdoor or high-wear applications.
Surface Treatment: Anodizing for exterior components; powder coating for interior decor.
Avoid Over-Specification: No need for expensive alloys—6063 meets most extrusion requirements.
