Xiamen JUST ALU: Your Best  Provider for Aluminum Extrusion Design

Choosing the Right Aluminum Alloy

Selecting the appropriate alloy and temper is critical to achieving the desired mechanical properties for your application.

  • For Decorative Applications: If your project prioritizes excellent surface finish and anodizing quality—such as for architectural trim or consumer goods—Alloy 6063 is the ideal choice.

  • For Structural Applications: When your component requires higher strength and structural integrity, Alloy 6061 offers superior mechanical properties.

While over 80% of our profiles utilize the versatile 6000 series, we expertly extrude from all major alloy series—including 1000, 2000, 3000, 5000, and 7000—to meet your specific requirements.

Optimizing Wall Thickness for Performance & Cost

Our designers engineer profiles for optimal cost-efficiency and structural strength. We recommend uniform wall thickness whenever possible, as it enhances extrudability and reduces cost. However, we can also produce profiles with varied wall thickness where the design demands it. The final design is influenced by extrusion force, speed, alloy selection, and profile geometry.

Precision Dimensions & Tolerances

We adhere to strict industry standards to ensure precision. Our standard dimensional tolerances follow Chinese national standards (GB5237.1-2008 for architecture and GB/T 14846-2008 for general engineering). Do you have a critical dimension requiring tolerances tighter than standard? Our engineering team is ready to collaborate and meet your exact specifications.

Enhancing with Surface Finishes

The right finish protects your aluminum and enhances its appearance. We offer a wide range of surface treatments to suit your needs:

  • Anodizing & Electrophoresis: Perfect for a durable, decorative finish on architectural and home fixtures.

  • Powder Coating: Provides exceptional durability and a vast spectrum of color options.

  • PVDF (Fluorocarbon) Coating: Our premium solution for ultimate resistance to fading and UV degradation, ideal for harsh outdoor environments.
