AL-Mg-Mn

High cost performance roof and facade materials

Aluminum alloy is widely used in building materials industry, and it greatly contributes to the modern building industry in terms of conform, lightness, durability, economy, environment protection.

Due to the advantages of medium strength, weathering resistance, waterlogging tolerance, easy to be bending and welded, AA3004 Alu-Mg-Mn alloy (AlMg1Mn1), it is widely recognized as a kind of roofing and walling materials which meet 50 years expected life span. For stronger corrosion resistance requirement, 5052 type aluminum alloy could be adopted for buildings in oceanic climate areas.

Al-Mg-Mn characteristics:
1. Low weight. Aluminum density accounts for 2.73g/dm3, only 1/3 of steel’s.
2. High strength. through proper composition, fabrication and heat treatment, very high strength can be acquired.
3. Corrosion resistant, rust proof; The naturally-formed oxide layer can prevent metal from oxidization and have good acid and alkali resistance.
4. Various surface finish and elegant appearance. The material can be anodized, electrophoresis-treated, polished or coated.
5. good formability and easy to be processed.
6. Good electric conductivity. Non-magnetization and low electric spark sensitivity, can avoid electromagnetic interference and reduce inflammability.
7. Easy installation. Aluminum alloy could be riveted, welded and glued, or connected by any other methods.
8. Environmental, 1005 recyclable.

Al-Mg-Mn product portfolio:
A.Original hammer tone, Stucco and Emboss
The main purpose of hammer tone
1.　Increase Alu-Mg-Mn rigidity;
2.　Avoid light pollution
3.　more even anodizing

B. Baking varnish coating（PVDF、PVF2、PE）
Roofing walling use Alu-Mg-Mn is usually treated through coil pre-coated technique, which has the advantages of good color uniformity control, paint film evenness, high quality, and environment protection.

The painting usually contains 70% or more PVDF element. B&G can customize any color from RAL, NCS, PANTONE or any special color designated by the customer.
