The Basic Knowledge of Aluminum(2)

Aluminum  alloys:
Code F * * is: free machining state
O * * is: annealing state
H * * is: working hardening state
W * * is: solid state heat treatment
T * * is: heat treatment state (different from F, O, H state)
*H * * * of subdivision state:
Aluminum alloy plate and strip rolling:
Rolling temperature can be divided into hot rolling, warm rolling (medium temperature rolling) and cold rolling
According to the arrangement of rolling mill, the machine can be divided into single stand, semi continuous and 
continuous rolling.
Thickness classification of aluminum roll:
Thicker than 80mm known as the special plate
The thickness of 4 ~ 80mm is called thick plate
The thickness of 0.2 ~ 4.0mm is called a thin plate
The thickness of less than 0.2mm is called aluminum foil
The calculation method of the length of the aluminum coil:
The weight of 1000kg / aluminum density (2.71), length width / thickness = per ton aluminum volume
* MOQ specifications of profiled aluminum coil:
Each furnace is 6 ~ 8 tons of aluminum, aluminum roll quantity of 6 tons to 8 tons.
* differential color coated aluminum coil quality:
The surface indentation, prints, bump and other anomalies is not obvious:
The damage of the coating and the coating is not allowed.
Bellows: not allowed bubbling (less than 10mm): not allowed
The defect (less than 3mm): 3mm /m2
Scratch: not allowed
Scratch: not allowed
Color: no obvious
