 · Aluminium is an odourless, tasteless, silvery-white metal. With increasing silicon and ductile and quite soft. The aluminium crystal has a face-centred cubic structure. The concentration of the lattice in the less pure metal results from the formation of impurity segregations. Purity also affects most other physical properties.

2  · Pure aluminum is highly abundant, making up 8% of the Earth's crust, and can be found in over 270 naturally occurring minerals. Pure aluminum is of special interest for its improved corrosion resistance, high ductility, high electronegativity and low atomic weight for surface finishing solutions.

 · Aluminum is a metal-like element with both metal and nonmetallic properties, situated in the boron and carbon family. Though aluminum is one of Earth's most abundant elements, it must be sourced from bauxite ore and undergo a production process before becoming commercially pure, viable aluminum.
