The base material of Sinopanel^® AL-MG-MN Panels is mainly composed of aluminum, magnesium, manganese and other alloying elements. The effective combination of various elements improves the material's strength, toughness and fatigue resistance, while enhancing its corrosion resistance—especially resistance to stress corrosion cracking. As a result, Sinopanel^® AL-MG-MN Panels integrate the corrosion resistance of aluminum, the lightweight property of magnesium, and the structural strength of manganese. They are widely used in architectural roofing, curtain wall systems and other fields requiring a balanced combination of durability, formability and cost-effectiveness.
