It is helpful to know the detailed production process of aluminium sheet for judging the quality of it. 


Basic procedures for producing aluminum sheet metal
1. Aluminum and anodised aluminium sheet and strips are supplied in hot rolling, annealing, various grades of soft and various heat treatment conditions. 
2. Preparing before hot rolling mainly includes quality inspection of ingot, soaking, sawing, milling, aluminium cladding and heating. 
3. In semi-continuous casting, the cooling rate is very high, the diffusion process in solid phase is difficult, and the chemical composition and structure of ingot are uneven, such as intragranular segregation, which reduces the plasticity. 
4. When there are defects such as segregation, floatation, slag inclusion, scarring and crack on the surface of ingot, milling surface (see milling surface of non-ferrous metal alloy ingot) should be carried out, which is an important factor to ensure good surface quality of finished product. 
5. Hot rolling: Hot rolling of aluminium alloy ingots is to provide blanks for cold rolling or directly produce hot-rolled thick aluminium plates
6. Hot rolling process of mirror polished aluminum plate includes pass reduction rate, rolling temperature, rolling speed, lubrication and cooling, etc.
