Aluminium

Aluminium is a soft, durable, light weight ductile and malleable metal with appearance ranging from silvery to dull gray depending on the surface roughness。
Aluminium is the most abundant metal in the Earth's crust，and the third most abundant element, after oxygen and silicon. It makes up about 8% by weight of the Earth's solid surface. Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation.
