1100 aluminum sheet is an ordinary pure aluminum sheet with aluminum content 99%, it is common used with 1060 aluminum sheet 1XXX series aluminum grades. The production process of 1100 grade aluminum sheet is electrolytic aluminum liquid – batching – refining in the furnace – resting – adding grain refining agent – online degassing and filtering – casting and rolling – cold rolling – annealing …

At present, the aluminum plate specifications commonly used are 1100 aluminum sheet for pcb and 5052 aluminum plate. When selecting metal substrates as circuit boards, the main consideration is its heat dissipation performance. 1100 aluminum sheet have higher heat dissipation than iron plates, so the heat dissipation performance is good, insulation and reliability are very stable, so it is well received …
