Aluminum Coil High Precision Sheet Slitting Machine Line
Aluminum sheet is softer in body and smooth in surface, some aluminum sheet is hard and high tensile, so aluminum Coil sheet slitting must be high precision, the slitting tools for aluminum sheet is unique, slitting speed is high when aluminum sheet gauge is small.
aluminum sheets can be pure aluminum or aluminum alloy, most frequently 1xxx, 3xxx, 5xxx, 7xxx series aluminum sheets
Features of aluminum sheet:
- it has good plasticity, easy to be processed
- aluminum sheet is light, its density is 2.7g/cm3, about one third of steel sheet
- The strength of aluminum sheet can be improved by cold rolling and annealing.
- Aluminum sheet has solid Al2O3 protection surface, is anti- corrosion.
- Aluminum sheet is softer in body and smooth in surface, must be well processed.
