Most Aluminum Profiles are produced from alloys in the 6000 series, which contain aluminum combined with magnesium and silicon. These alloys are widely used because they offer excellent extrudability, strength, corrosion resistance, and surface finish quality.
Among them, 6063 aluminum alloy is the most commonly used for architectural aluminum profiles due to its smooth surface and good anodizing performance. 6061 aluminum alloy is known for its higher mechanical strength and is often used in structural applications such as industrial frames and transportation components.
Other alloys like 6082 and 6005 are also used in heavy-duty industrial applications where higher strength and durability are required. The choice of alloy depends on the specific application, load requirements, and environmental conditions.
