Are you in search of a high-strength, versatile, and readily available aluminum plate for your next project? Look no further than the industry workhorse – the 4×8 Foot 6061 Aluminum Plate. At Flait Aluminum, we specialize in supplying top-tier 6061-T651 aluminum plate that delivers unmatched performance and reliability for a vast range of applications.
The 4×8 foot (1220mm x 2440mm) size is the cornerstone of countless manufacturing and fabrication processes. Its standardized dimensions minimize waste, simplify handling, and streamline production, making it the most efficient and cost-effective choice for both large-scale industrial runs and custom one-off projects.

Our 6061 aluminum plates are more than just metal; they are a testament to precision engineering. The T651 temper signifies that the plate has been solution heat-treated, stress-relieved stretched, and artificially aged. This process delivers three critical advantages:
Superior Strength & Machinability: Achieve excellent mechanical properties and a smooth, clean finish on your machined parts with minimal risk of warping.
Exceptional Flatness: The stretching process ensures superior internal stability, which is crucial for precision machining, fabrication, and structural applications.
Excellent Corrosion Resistance: The magnesium-silicon alloy offers great resistance to atmospheric and chemical corrosion, ensuring long-term durability.
We ensure every sheet meets rigorous standards, guaranteeing consistency and quality you can depend on.
