Comparison with 3105 / 1100 / 5052 Aluminum Coil
Compared with other commonly used aluminum alloys, A3003 H14 aluminum coil offers a well-balanced solution.
3105 aluminum coil provides slightly higher strength and is often used for color-coated roofing panels, but it generally comes at a higher cost and with less forming flexibility than A3003 H14.

1100 aluminum coil, as a nearly pure aluminum alloy, has excellent conductivity and corrosion resistance but very low mechanical strength, making it unsuitable for roofing or applications requiring structural stability.
5052 aluminum coil contains magnesium and delivers higher strength and superior marine corrosion resistance. However, its higher price and reduced formability make it less economical for standard roofing, HVAC, and insulation projects.
Overall, A3003 H14 aluminum coil stands out as a versatile and cost-efficient choice, offering better strength than 1100, better formability than 5052, and wider general-purpose applicability at a lower cost than 3105. With fast delivery, flexible MOQ, and factory-direct supply, it is a reliable solution for global construction and industrial buyers.
