Introduction and Characteristics of Al-Mg-Mn sheet
Introduction
Aluminum magnesium manganese sheet is a very cost-effective roof, wall materials.
Aluminum alloy has been widely used in the construction industry, and has played an important role in the development of modern building towards the direction of comfort, light weight, durability, economy and environmental protection.
AA3004 aluminum, magnesium and manganese alloy (AlMg1Mn1) is generally recognized as roofing and exterior wall material with a service life of more than 50 years for architectural design due to its advantages of moderate structural strength, weather resistance, corrosion resistance, and easy bending and welding. According to the Marine climate building design, 5052 ship grade aluminum alloy material with stronger corrosion resistance can be selected.
The reason why aluminum roofing material has such excellent durability is because the aluminum sheet and the atmosphere contact will produce a layer of aluminum oxide film on the surface. This layer of oxide film to protect the inner layer of aluminum sheet from further corrosion. This layer of oxidation film has good chemical resistance, so it is suitable for industrial buildings, air pollution is relatively serious or areas with a Marine climate. The authorities have done testing, every year aluminum sheet due to corrosion and loss of thickness of 0.5 micron.
Characteristics
(1) Light weight: Aluminum has a density of 2.73*103 Kg/m³, only 1/3 that of steel.
(2) High intensity: High strength can be achieved by composition, processing and heat treatment.
(3) Corrosion resistance: Self - anti - rust ability, the formation of oxidation layer, can prevent metal oxidation corrosion, good acid and alkali resistance.
(4) Diverse and beautiful surface treatment: It can be anodized, electrophoresis, chemical treatment, polishing, paint treatment.
(5) Good plasticity and easy processing.
(6) Good electrical conductivity: Non-magnetization and low spark sensitivity can prevent electromagnetic interference and reduce flammability under special circumstances.
(7) Easy installation: Aluminum metal can be riveted, welded, glued and other ways of connection.
(8) Environmental protection: 100% recyclable.
