What is rolling processing?

リカザイ株式会社|圧延加工とは

The special strength of cold rolling is that it allows for precise
rolling without oxidizing the metal surface!
We pass the metal foil through the cold-rolling mill again and again,
slightly reducing the space between the rollers each time.

To a thickness of only 0.001mm[1 micron]

(For reference, commercially-available aluminium foil has a thickness of 12 microns.)
