3003 Aluminum Plate

Our 3003 Aluminum Plate is a non-heat-treatable alloy primarily composed of aluminum and manganese, which enhances its corrosion resistance and strength compared to pure aluminum. It is a cost-effective solution for applications where moderate strength and excellent workability are required.

The 3003 alloy is easy to form, bend, and weld, making it suitable for roofing, siding, kitchen equipment, storage tanks, and decorative panels. Its natural resistance to rust and weathering ensures long service life even in outdoor conditions.

We offer precision-cut plates in multiple thicknesses, widths, and lengths to suit your exact project requirements. The 3003 Aluminum Plate provides a balance of durability, affordability, and performance, making it one of the most popular choices for general-purpose aluminum sheet and plate applications.
