Cooking Utensil
Why is it that aluminum used for materials like airplane parts and packaging is also used for cooking utensils?

Aluminium is a soft, lightweight, malleable metal . Aluminium is nontoxic, nonmagnetic, and nonsparking. It is also insoluble in alcohol.The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel. It is ductile, and easily machined, cast, and extruded.
Corrosion resistance is excellent due to a thin surface layer of aluminium oxide that forms when the metal is exposed to air, effectively preventing further oxidation.
Lightwieght, strong, doesn’t rust.
It is light, yet durable. It also has some degree of flexibility (like many metals) which is also important for planes.
Light, strong, doesn’t oxidize, and can be recycled, so it’s also inexpensive compared to other minerals.
These points are in favour of Al:-
a) High strength to weight ratio
b) Doesn’t get corroded
c) Good plastic flow and malleability ie. can be given shapes easily…
Also it can be alloyed to useful alloys like duralamin which further enhances its mechanical properties…
