Al-Mg-铁合金板

Aluminum metal is widely used in the architecture to comfort , light , durable , economic , and environmental protection direction play an important role ,its features as following: Weight: Aluminum density 2.73g per meter,only the steel of 1/3 strength. Intensity: Through melting and heat treatment method and can achieve very high strength, even the construction of large aircraft structures. Corrosion resistance: Outdoor aluminum is durable and reliable construction materials ,it has a self-rust function of the surface in the natural environment can form a thin layer of dense oxide layer, to prevent Continue in the air oxidation of metal corrosion, but also has a variety of acid corrosion resistance ability. Surface finish and elegant appearance. Can be anodized, electrophoresis, chemical processing ,polishing ,paint handing. Easy production of metal forming. Can extrusion,stretching,rolling,punching,spinning,casting and forging.Aluminum can be rolled into a variety of thickness , or even very thin aluminum foil. Good conductivity :Non-magnetization and low electric spark sensitivity , can avoid electromagnetic interference and reduce the flammability under special circumstances. Links convenience. Aluminum can be riveting, welding(brazing and welding ,etc.),adhesives and other means to connect. Recyclable: High value of aluminum recycling, the cost of long-term use of more economical,in the conservation of natural resources has played a positive role.
