ALUMINIUM
Aluminum is a light gray metal with a low mass/volume.
Aluminum is sometimes used as a tool handle, especially for fine files. Its lightness allows to maintain the balance of the tool and its sensitivity. Aluminum is also sometimes used to make watch cases.
Advantages:
Its low density.
Disadvantages:
Although its oxidation remains on the surface without going deep, it is a metal that oxidizes and can therefore change color.
