Color coated aluminum alloys can vary depending on the desired application and the specific color required. Generally, aluminum alloys in the 1xxx, 3xxx, and 5xxx series are most commonly used for color coated aluminum.
The 1xxx series alloys are pure aluminum and have excellent corrosion resistance and good workability. However, they are soft and not suitable for applications where high strength is required.
The 3xxx series alloys, such as 3003 and 3105, have moderate strength and good workability. They are often used for roofing, siding, and other architectural applications.
The 5xxx series alloys, such as 5052 and 5083, have high strength and excellent corrosion resistance. They are commonly used in marine and automotive applications.
In addition to the alloy selection, the choice of coating also plays an important role in the final appearance and performance of the color-coated aluminum. Polyester, polyurethane, and fluorocarbon coatings are commonly used for color-coated aluminum.
