Custom 6061 6063 Extruded Aluminum Profile Manufacturer

6061 Extruded Aluminum Profiles

Chemical Composition

Mechanical Properties

• Strength: Moderate to high strength (ultimate tensile strength up to ~310 MPa in T6 temper), with excellent fatigue resistance and good ductility.
• Heat Treatability: Can be readily heat-treated (e.g., T6 temper for maximum strength or T4 for formability) to achieve specific mechanical properties.
• Extrudability: Good extrudability, allowing formation into complex shapes, though slightly lower than 6063 due to its higher copper content.
• Corrosion Resistance: Good general corrosion resistance, especially in atmospheric environments, but may require surface treatment (anodizing, painting) for harsh conditions.
• Weldability: Excellent weldability, making it suitable for structural assemblies.

Applications

• Industrial & Mechanical: Used for structural components in machinery, robotics, and automation (e.g., frames, brackets, gears).
• Aerospace & Automotive: Lightweight parts like aircraft interior structures, truck frames, and suspension components.
• Marine & Outdoor: Boat trailers, marine hardware, and outdoor equipment due to moderate corrosion resistance.
• DIY & Prototyping: Popular in custom projects (e.g., 3D printer frames, bicycle parts) for its balance of strength and workability.

6063 Extruded Aluminum Profiles

Chemical Composition

Mechanical Properties

• Strength: Moderate strength (ultimate tensile strength up to ~240 MPa in T6 temper), lower than 6061 but sufficient for many structural and decorative applications.
• Extrudability: Exceptional extrudability, enabling intricate, high-precision shapes with smooth surfaces, making it the ideal choice for complex profiles.
• Surface Finish: Excellent anodizing and plating capabilities, providing a clean, aesthetic appearance—critical for architectural use.
• Corrosion Resistance: Superior resistance to atmospheric corrosion, especially when anodized, making it suitable for outdoor environments.
• Heat Treatability: Typically heat-treated to T5 or T6 tempers, though it is less commonly used in high-stress applications compared to 6061.

Applications

• Architecture & Construction: Primary use in window/door frames, curtain walls, railings, and decorative trims due to its aesthetic appeal and corrosion resistance.
• Electronics & Consumer Goods: Enclosures for electronics (e.g., laptops, LED fixtures), as well as furniture and signage.
• Transportation: Lightweight components in trains, buses, and automotive interiors where formability and appearance matter.
• Industrial Extrusions: Framing systems (e.g., modular workbenches, conveyor rails) and precision components requiring tight tolerances.
