aluminum metal for modern architecture to comfort,durable,economic,and environmental protection direction play an important role,it has the following features: Weight.Aluminum density only the steel of 1/3 strength. Intensity.Through melting and heat treatment method 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 handling. Easy production of metal forming.Can extrusion, stretching,rolling,punching,spinning,rolling,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 recying,the cost of long-term use of more economical,in the conservation of natural resources has played a positive role.
