I mentioned before why 6063 aluminum rods were chosen as greenhouse aluminum materials. Today, let's delve into the composition and content of aluminum rods and how they affect greenhouse aluminum materials?

The main chemical components in the 6063 model are aluminum magnesium silicon, as well as some other elements and impurities such as iron. Within the composition range of 6063 aluminum bars specified in the national standard GB/T3190, different values of its chemical composition will result in different profile characteristics, making it impossible to control the comprehensive performance of greenhouse aluminum profiles. Therefore, controlling the composition of aluminum bars is crucial.

The composition and content of 6063 aluminum bars determine whether the greenhouse aluminum alloy profiles produced are of high quality. After a long period of experience accumulation and research, it has been shown that controlling the amount of Mg2Si in 6063 aluminum alloy profiles within the range of 0.75% to 0.80% can meet the requirements of mechanical properties. Under normal extrusion coefficient (greater than or equal to 30), the tensile strength of the profile is within the range of 200-240 MPa. By controlling the alloy in this way, the greenhouse aluminum produced not only has good corrosion resistance, but also high strength and good surface treatment performance.

Aluminum bars should also pay special attention to strict control of impurity Fe. If the Fe content is too high, it will increase the extrusion force, deteriorate the surface quality of the extruded greenhouse aluminum, increase the color difference of anodizing, and make the color dull and dull. Fe also reduces the plasticity and corrosion resistance of greenhouse aluminum. Practice has proven that controlling the Fe content within the range of 0.15% to 0.25% is ideal.
