What is the difference between composite aluminum sheet and aluminum alloy sheet material and coating?
Composite aluminum plate: two layers of 0.5mm thick pure aluminum plate sandwiched with PVC or PEC plastic roll, heat-sealed.
Aluminum alloy veneer: 2 ~ 3mm aluminum alloy plate.
Composite aluminum plate: one-time roll printing, the coating thickness is generally 20μm.
Aluminum alloy veneer: 2 or 3 times of spraying, the coating thickness is generally 30-40 μm.
