The key characteristics of aluminum

Aluminum is one of the most significant substances in the globe and is used in an extraordinary scope of industries. It is light, strong, ductile and resistant to corrosion. These features allow aluminum to be widely used in the aerospace, transport and construction.

The physical, chemical and mechanical characteristics of this metal were thoroughly studied. That allows to foretell its behavior in a certain surrounding and under the external factors, which helps architects, manufacturers and designers to determine the choice of the right matter for a particular use.

Important characteristics of aluminum:

Corrosion resistance

Due to the natural Al2O3 layer, aluminum shows high resistance to corrosion, which allows aluminum to be widely used in various fields with many operating conditions. If we compare aluminum and steel, the former does not form corrosion products that harm the outward of the finished product and construction.

Easy to machine and cast

The high ductility of aluminum makes it possible to apply all known methods of metal processing to it. Aluminum lends itself very well to forming or bending; used in a wide range from ductile and soft technically pure metal to alloys with high-strength properties that can be rolled into a thin layer without losing strength and anti-corrosion properties. Thus, the wide range of stuff can be made of aluminum starting from foil, cans for food and drinks to pipelines and irrigation pipes.  

Lightweight yet durable

Light weight - three times lighter than steel. At the same time, aluminum has a high specific strength, other words, strength per unit mass. Strength is maintained even at low temperatures; it is often employed in cryogenic temperatures. 

Non-magnetic and non-flammable

Due to these important features aluminum is an irreplaceable element for the electrical and electronic industries.

High thermal and electrical conductivity

The electrical and electronics spheres fail without aluminum -  due to its non-ferromagnetic properties it's an ideal element for both industries. The thermal conductivity of aluminum alloys is an advantage in heat exchangers, evaporators, electrically heated appliances and utensils, as well as in car rims, cylinder heads and radiators.

High reflectivity

Polished aluminum exhibits good reflectivity. No wonder, it is chosen for the production of various finishing, decorative and functional elements, including high-precision equipment, devices and lasers.


Aluminum is non-toxic and is often used for food and drink containers as it can come into direct contact with food.

Attractive exterior

Appealing natural outward. Easily exposed to covering with the protective and/or decorative coatings, such as anodizing or powder coating.

Eco friendly

Can be recycled multiple times, resulting in great economical and environmental advantages.
