Aluminum is the third most abundant element in the earth's crust after oxygen and silicon. The main sectors of use include industries such as transportation, especially air transport. This is followed by its use for cans, pipes, containers, electrical cables, bridges, specialized equipment, etc.
It is also very present in the construction industry, from windows to mobile homes. Thanks to all these uses and characteristics, it was considered for decades more valuable than gold.
The different alloys of this light but resistant material allow us to use it in moderately aggressive environments, such as in the kitchen, where it is used in pots, pans and coffee makers without leaving an aftertaste in the food.
If we compare 2.70 kg of aluminum, it will be equivalent to around:
- 7.9 kg of steel
- 8.93 kg of copper
The yield strength of aluminum is practically lower than that of steel. However, this disadvantage is offset by a lower density, maintaining a lower weight than other metals.
Different aluminum alloys

Aluminum series 1000
Composed of 99% pure aluminum. It is mainly used for chemical plants, heat exchanges, electrical conductors and architectural and decorative applications.
Its main characteristics are:
- Excellent corrosion resistance
- High thermal and electrical conductivity
- Good workability
Aluminum series 2000
Known as Avional. It has been used for decades in the aeronautical industry for the construction of structural elements of airplanes. It is also present in precision tools.
Some of its characteristics are:
- Lightness
- Hardness
- Low corrosion resistance
- Good mechanical characteristics
Aluminum series 3000
The main element of this alloy is manganese. It increases the mechanical strength of the series, but has less ductility. It is used for kitchen utensils, containers and pressure pipes.
Aluminum series 4000
Silicon is the main alloying element of this series, which provides good wear resistance. Other alloying elements can also be added, such as copper and magnesium.
Aluminum series 5000
Known as Peraluman. The main element of this alloy is magnesium, after heat treatment they develop intermediate mechanical characteristics. It is used to work in the marine environment and in the automotive industry for the construction of bodywork.
Some characteristics of this series are:
- Mechanical characteristics
- Resistance to corrosion and melting
- Ideal for welding
Aluminum series 6000
Also known as Anticorodal. The main elements of this alloy are silicon and magnesium. It is used in frames for motorcycles, bicycles and generally welded structures.
Some of its main characteristics are:
- Good mechanical resistance
- Good formability
- Good level of manageability
- Cutting capacity
- Welding capacity
- Corrosion resistance
Aluminum series 7000
Commercially known as Ergal, the main element of this series is Zinc, with possible additions of magnesium. This alloy is used when lightness is required from aluminum, such as in aeronautical structures and means of transport, especially in the motorcycle sector and in bicycle frames.
Corrosion resistance
- Good manageability
- Fusion weldability
