The mirror polished aluminum plate can be divided into multiple different types according to different methods. From the perspective of alloy composition, each type of aluminum plate has multiple different alloys ingredients. By comparing mirror aluminum plates with different alloy compositions, they are mainly different in anti-rust performance and strength.
The anti-rust properties of mirror polished aluminum plate with different alloy compositions are different. Among them, ordinary aluminum alloy aluminum plates do not have good anti-rust properties, so they cannot meet the application requirements of anti-rust. If there are anti-rust requirements, they must not be used. Aluminum-manganese alloy aluminum plate is a kind of anti-rust aluminum plate, which has a certain anti-rust ability, but it can only meet the needs of ordinary anti-rust applications, and cannot be used in areas where early anti-rust requirements are very strict. The aluminum-magnesium alloy mirror aluminum sheet has the best anti-rust performance and can meet the high anti-rust requirements. If the anti-rust requirements are very strict, it is necessary to choose the aluminum plate of this material.
In addition, the strength of mirror polished aluminum plate with different alloy compositions is also different. Among them, ordinary aluminum alloy mirror panels have the worst strength, followed by aluminum-manganese alloy aluminum plates. Aluminum-magnesium alloy aluminum plates have the best strength. However, the difference in strength between the three aluminum plates with different alloy compositions is not particularly large.
