The main alloy element of the 3000 series aluminum sheet is manganese, all of which are also called Al-Mn alloy. The commonly used alloy brands are
3003 aluminum sheet, 3004 aluminum sheet and 3A21 aluminum sheet. Because the hardness of 3000 series
aluminum sheet is high than pure aluminum sheet, so the use is more extensive, and antirust function is also relatively strong. Because of its good corrosion resistance, it has good resistance to the atmosphere, fresh water, sea water, food, organic acid, gasoline and neutral inorganic saline solution, so it can be used in many special environments.
In recent years, with the rapid development of the economy, the construction industry decoration standards are gradually improving. Some of the new construction of the external walls of the use of high-grade decoration materials is becoming increasingly popular, so many businesses began to use composite aluminum curtain wall to decorate the appearance, not only beautiful and generous, and corrosion resistance. Aluminum veneer curtain wall need to use high strength and corrosion resistant alloy sheet, so the 3000 series aluminum sheet can be replaced, its commonly used alloy brand is 3003, and the state is H24. At present, it is mainly used in some public buildings, there are very few high-end residential areas to use local.
The characteristics of 3000 series curtain wall sheet is light weight, steel appropriate, energy dissipation and sound-proofing, the decoration effect is good, the surface can be corrosion, coating, printing, embossing and other two processing, and the cost is much lower. So it is widely used in the market. Aluminum composite board in the decoration industry plays a role in beautification, and the material is light, easy processing, high strength and no deformation. 3000 series aluminum sheet can also be processed into production pattern plate. Because pattern plate has many advantages of anti-slip and strengthen, in the transportation, construction, decoration, equipment around the floor, machinery, shipbuilding and other fields have a wide range of applications. Because the use does not have high requirements on the mechanical properties of tread plate, the main performances of pattern plate are the flowering rate, pattern height and elevation pattern
