Is the aluminum plate with a thickness of more than 0.2mm to 500mm, 200mm width, length less than 16m aluminum material called aluminum plate or aluminum sheet, aluminum is below 0.2mm, 200mm within the width of the row material or bar (of course, with the progress of the large equipment, the width can be 600mm row material also more). Aluminum sheet refers to the rectangular plate made of aluminium ingot rolled and divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium thick aluminum plate and pattern aluminium plate.
Aluminium plate is usually divided according to the following two kinds:
1., according to the alloy composition is divided into:
High pure aluminium plate (rolled by high purity aluminium with more than 99.9 content)
Pure aluminium plate (basically rolled from pure aluminium)
Aluminum alloy (composed by aluminum and alloy auxiliary usually aluminum copper, aluminum manganese, silicon aluminum, aluminum and magnesium, etc.)
Composite aluminum brazing sheet (or special purpose aluminum material composite material through a variety of means)
Aluminum aluminum (aluminum coated outside the thin aluminum sheet used for special purposes)
2. according to the thickness is divided into: (unit mm)
Sheet (aluminum, sheet) 0.15-2.0
Sheet (aluminum) 2.0-6.0
Medium plate (aluminum, plate) 6.0-25.0
Thick plate (aluminum, plate) 25-200
Five ribbed pattern aluminium plate
Five ribbed pattern aluminium plate
Over 200 thick plates

The supply of aluminum material in five major areas of excess production - supply aluminum ceramic plate punching aluminum aluminum aluminum profiled carved ceiling network strong corrugated plate materials and other products in five major areas of excess capacity "from the beginning of the 1 tons, to 8 tons now, also said overcapacity, Deputy Secretary General of the iron and steel industry association under China" China investment "said in an interview. Recently, the China Association of steel released, when China's steel production capacity has reached 8 tons, but the practice of the Shanghai Iron and steel production capacity as long as 4 tons, there are 4 tons of capacity, without the approval of the state.
Since 1999, when the cap has been put on excess capacity, the steel industry has continued to expand as demand increases. On the basis of demand forecasting, the state has made serious plans for the steel industry's capacity expansion. However, as demand has repeatedly broken down the planning capacity, the market capacity has repeatedly broken the state planning. As in 2009, the State Council, "iron and steel property adjustment and ZTE planning" predicted that in the past, China's crude steel consumption was 4.3 tons, but in practice consumption amounted to 5.7 tons. China Steel Association estimates that crude steel consumption will reach 6.8 tons, while the country agreed to steel production capacity of only 4 tons, there are 4 tons of illegal production capacity in the market will compensate for the demand gap.
In fact, aluminum materials in the past 10 years the government micro regulation, China steel, cement, nonferrous metals and other industries has been defined as "overcapacity" industry, and is applicable to a relatively serious land, taxation, project approval and other types of property policy
