6 Advantages of Aluminum

advantages of aluminum alloy

Aluminum is a highly versatile metal with numerous advantages; it is known for being both lightweight and flexible. It can be cast, melted, formed, machined, and extruded, allowing it to be manufactured into a variety of shapes and then fabricated to suit a wide range of applications.

Aluminum is becoming more popular due to its extreme versatility and strength, especially given the benefits it provides. Aluminum extrusion allows it to be supplied in increasingly complex designs. This extrusion is available in a variety of finishes, including anodized, milled, and painted, and can then be machined or fabricated.

Advantages of aluminum:

Thermal and electrical conductivity

Aluminum is a great conductor of both heat and electricity. The thermal conductivity of aluminum is approximately 50-60% of that of copper, making it ideal for the large-scale production of cooking utensils. Thermal conductivity refers to the transfer of heat from one medium to another; thus, aluminum heat exchangers are used in the chemical, food, and aerospace industries. Aluminum is an effective electrical conductor due to its high conductivity (1350), which is approximately 62 percent of the International Annealed Copper Standard (IACS) and has about one-third the specific gravity of copper.

Impermeable and odorless.

Aluminum is 0.007mm thick and sufficiently impermeable, emitting no smell or taste even when rolled like foil. It is also non-toxic, which, combined with its odorless and impermeable properties, makes it ideal for packaging pharmaceuticals and foods.

Absorption of sound and shock

Aluminum is a good sound absorber, making it ideal for roof ceilings and shock absorbers in automobiles. Aluminum foam is permeable to sound and shock due to its porosity, material composition, thickness, and various types of treatment.

Corrosion resistance

When aluminum is exposed to air and moisture, an oxide skin forms to protect the aluminum surface from extreme oxidation. This self-protecting oxide layer gives aluminum its resistance to deterioration and weathering, even in industrial environments that promote weathering. Anodizing treatments can also be used to improve the surface’s oxide layer resistance.

Excellent strength-to-weight ratio

Aluminum has a much higher strength-to-weight ratio than construction steel. This property makes it suitable for designing and building strong and lightweight structures, which have many advantages for moving structures such as ships, vehicles, and aircraft.

Capability to complete

Aluminum does not require a protective coating in the majority of its applications. Finishing techniques such as sandblasting, polishing, and wire brushing meet the majority of finishing requirements, and in most cases, the surface finish achieved is sufficient without the need for additional finishing. Surface finishes such as paint, chemical, and electrochemical techniques are used where pure aluminum or additional protection is required.


In conclusion, aluminum is a remarkable material due to its thermal and electrical conductivity, impermeability, odorlessness, absorption of sound and shock, corrosion resistance, and its excellent strength-to-weight ratio. It is also capable of completing a variety of applications without the need for a protective coating. These qualities make aluminum an ideal material for a variety of applications, from cooking utensils to roof ceilings and vehicles.
