1100 aluminum plate and 3003 aluminum plate are two kinds of aluminum plate materials commonly used in building curtain walls. They have some similarities and differences.Both 1100 aluminum plate and 3003 aluminum plate are lightweight materials with low density. This makes them ideal for building curtain walls as they do not add excessive load to the structure. At the same time, both have good corrosion resistance, which can effectively resist the erosion of most chemical substances and environments, thereby prolonging the service life of the curtain wall. Both 1100 aluminum plate and 3003 aluminum plate have good processing performance, and can be bent, cut, welded and surface treated. This makes them easier to process and adjust when fabricating and installing curtain walls.
However, there are some differences between 1100 aluminum plate and 3003 aluminum plate for building curtain wall,the following takes 1100 H24 aluminum plate and 3003 H24 aluminum plate as examples to introduce the differences between these two aluminum plates.
1100 aluminum alloy is a pure aluminum alloy, mainly composed of aluminum, with a small amount of copper and other elements. 3003 aluminum alloy also contains aluminum, but also contains a higher proportion of copper and manganese.
|Alloy||Temper||Thickness (mm)||Mechanical properties|
|Tensile Strength（Mpa）||Yield strength Rp0.2(MPa)|
3003 aluminum alloy has higher strength than 1100 aluminum alloy. This makes the 3003 alloy more resistant in the face of greater wind pressure or other external forces.
In addition, due to the addition of copper and manganese elements, 3003 aluminum alloy has better corrosion resistance than 1100 aluminum alloy. This makes Alloy 3003 advantageous in curtain wall applications exposed to high humidity or corrosive environments. Finally, there is a difference in price between them. In general, the price of 1100 aluminum alloy is lower than that of 3003 aluminum alloy. This may be a factor of choice in projects with limited budgets.
