Machined aluminum block, and then after heating or annealing after hot rolling, rolling into a thickness of 3.175 ~ 0.584㎜ aluminum. The aluminum is then annealed, after single or double (when aluminum rolled to a thickness of about 0.038㎜ time, you can put two aluminum rolling mill at the same time, the two together into a rolled aluminum foil) repeatedly cold rolling, rolling into a metal called aluminum foil rolling aluminum foil (metal foil or aluminum foil), which is commonly known that the aluminum foil.
The content of 99.35% - 99.97% of aluminum ingot, first performed on the milling machine repair, remove burrs aluminum surface oxidation spots and bubbles and other defects, processed into smooth aluminum block.
