The quality of the aluminum ceiling tiles largely determined by the materials it uses. At present, the raw materials used in the aluminum gussets on the market mainly include aluminum-magnesium alloys, aluminum-manganese alloys, and aluminum alloys. In the meantime, the aluminum-magnesium alloy is the best. The biggest advantage of this data is that it can resist oxidation. Together with the manganese content, it has the necessary strength and rigidity. It is the most ideal material for smallpox. Followed by aluminum-manganese alloy, the strength, and stiffness of this data is slightly better than that of aluminum-magnesium alloy, but the oxidation resistance is slightly lower than that of aluminum-magnesium alloy. If both sides are protected, it can basically handle the defects of aluminum oxide and magnesium alloy.
