Chung Metal supplies aluminium flat bars and rods with different alloys, sizes, and finishes. As stock material for machining, fabrication, and structural components, our aluminium flat bars and rods are processed for metallurgical quality, dimensional accuracy, and surface finish. Our stock is utilized by customers in various industries for lightweight parts that are corrosion‑resistant, frames, rails, and structural supports. Our supply guarantees welded and machined parts have consistent aluminium stock from prime sources.
Depending on the alloy (e.g. 5xxx, 6xxx, 7xxx series), composition varies: magnesium, silicon, zinc, copper, etc. Typical tensile strengths range widely (200–600 MPa) and yield strength accordingly. Flat bars and rods have density ~2.68 g/cm³. Mechanical properties depend strongly on alloy and temper—some emphasize strength (e.g. 7xxx series), others corrosion resistance (5xxx series). Aluminium in bar/rod form is ductile, machinable, and forms easily depending on temper.

Yes, aluminum flat bars are corrosion-resistant due to the natural oxide layer that forms on their surface, protecting them from environmental factors like moisture and air, preventing rust and degradation.
Aluminium flat bars can withstand moderate temperatures but may lose strength at high temperatures above 150°C (302°F). Prolonged exposure can lead to deformation and reduced mechanical properties.
Yes, aluminum rods can be customized in size and length according to specific requirements. Manufacturers often offer custom machining services to meet exact dimensions and tolerance specifications.
Used in frameworks, structural supports, rails, bars, machine components, brackets, machining stock, rails, and construction pieces. Aluminium rods and flat bars are standard for chassis, frameworks, supports, tool holders, facades, and architectural pieces. Due to their shape, they are utilized for applications that need one direction of strength (flat bars) or round shapes (rods) for use in shafts, pins, rods, and pins. Their resistance to corrosion enables them to be used in marine and outdoor settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
