Aluminum-magnesium-manganese plate, also known as aluminum-magnesium-manganese alloy plate or Al-Mg-Mn plate, is an aluminum alloy material with aluminum as its core component. It incorporates small amounts of magnesium and manganese, along with other trace elements. This material is widely used as metal sheeting in roofing and wall systems for large public buildings.

Advantages
High Corrosion Resistance: A dense aluminum oxide protective layer forms on the metal surface, preventing further corrosion of the underlying metal.
Lightweight: With a density of approximately 2.73 g/cm³, it weighs only one-third as much as coated steel.
Excellent Strength and Rigidity: Magnesium and manganese elements enhance strength while maintaining good flexibility.
Exceptional Formability: Easily stamped, drawn, and rolled into shape.
Reliable Joining Methods: When fabricated into aluminum-magnesium-manganese alloy roof panels, either standing seam or low-profile seam systems can be selected.
Long service life: Aluminum-magnesium-manganese alloys can last over 50 years.
Aesthetic appeal and decorative versatility: Wanzhi Al-Mg-Mn metal materials support diverse color coatings and various types of film lamination.
Recyclable and eco-friendly: Aluminum is a 100% recyclable metal.
Applications
Large public buildings: Stadiums, airport terminals, train stations, theaters, convention centers.
Commercial and Industrial Buildings: Large shopping malls, exhibition halls, logistics warehouses, factories.
High-End Residential Buildings: Residential and villa projects prioritizing design aesthetics and durability.
Automotive: Body panels, engine components, etc.
Aerospace: Manufacturing aircraft components, satellite parts, etc.
Electronics, Electrical Appliances, and Petrochemical Industries.
Al-Mg-Mn and ZAM
| Properties | Aluminum-Magnesium-Manganese Plate | Zinc-Aluminum-Magnesium ZAM |
| Core Nature | Aluminum alloy | Coated steel plate |
| Main Components | Mainly aluminum (Al), containing magnesium (Mg), manganese (Mn) | Steel substrate + Zinc-Aluminum-Magnesium alloy coating (Zn, Al, Mg) |
| Density/Weight | Light (Approx. 2.73 g/cm³) | Heavy (Approx. 7.85 g/cm³) |
| Corrosion Mechanism | Forms a dense aluminum oxide passivation layer on the surface | “Self-healing” effect of the coating + Barrier protection |
| Corrosion Resistance | Excellent, especially resistant to atmospheric and chloride ion corrosion | Excellent, far superior to traditional galvanized steel, especially in cut and scratch protection |
| Strength and Rigidity | Medium, good flexibility | High, great rigidity |
| Plasticity/Formability | Excellent, easy to roll into complex curves | Good, better than ordinary galvanized steel but not as good as aluminum-magnesium-manganese |
| Appearance and Aesthetics | Modern look, can be anodized or treated for high-end finishes, good texture | More industrial, various coating options, but different texture |
| Service Life | Very long (typically over 50 years) | Long (typically 20-40 years, depending on coating and environment) |
| Cost | High | Medium, cost-effective |
