Product Introduction
The aluminium hollow bar is precision-engineered from high-grade aluminium alloys, such as the 6000 series (e.g., 6061, 6063), which incorporate magnesium and silicon to enhance mechanical properties . These alloys undergo processes like extrusion or centrifugal casting to create seamless hollow profiles with uniform wall thickness and exceptional dimensional accuracy. The result is a robust yet lightweight bar with a hollow core, available in custom sizes, shapes, and surface finishes to suit specific requirements.
Unlike solid bars, the aluminium hollow bar maximizes material efficiency by eliminating unnecessary weight while maintaining structural integrity. Its design allows for seamless integration into complex assemblies, making it a superior alternative to traditional materials like steel. The versatility of the aluminium hollow bar extends to its compatibility with various surface treatments, including anodizing, powder coating, and polishing, which further enhance its durability and aesthetic appeal .
