High strength to weight ratio:
There is a combination of high strength and lightweight in only a few materials in nature. The high strength of some Aluminum alloys is comparable to the strength of steel.

Ductility: 
Aluminum can be deformed by various methods of forming metals. Aluminum can also be connected by welding, soldering, gluing, and riveting.

Elasticity:
Some aluminum alloys can regain their original state after the force is removed if they are affected by force or impact in a certain range.

High thermal conductivity: 
Aluminum is the most conductive Metal after silver, copper, and gold, which is why it is used in the manufacture of kitchen utensils, water, and oil heat exchangers.

Non-toxic: 
Solid aluminum alloys with a surface oxide layer are non-toxic. 

Electrical conductivity: 
In an equal volume, aluminum, like copper, passes about 62% of its electricity. It has the highest electrical conductivity after copper, copper, and gold.

Ability to reflect light, aluminum Ability to reflect more than 80% of visible light rays and invisible rays that have a visible wavelength at both ends of the light spectrum. Non-sparking, although aluminum has a very high electrical conductivity, it does not produce sparks.
