An overview of aluminum

Aluminum


Aluminum (to the) is the non-ferrous metal's highest consumption in the world and the most abundant in the Earth's crust, is characterized by being a very lightweight metal, with a specific gravity of 2.7 (g/cm3), which is a third of the steel. It is characterized by being a ductile metal and has a low melting point and density. It flows easily in State cast and therefore it can be processed in a variety of ways both a state how hot cold.

High ductility allows that aluminum products are formed with a close to the final product design, its strength may vary through the addition of small amounts of other metals (alloys).

Special aluminium alloys can reach the same strength as steel. To own metal forms a protective oxide layer (which is formed immediately if the metal is cut or scratched) is highly resistant to corrosion. Different types of surface treatments can further enhance this property.

What is an Extrusion?

Extrusion is a process of transformation by plastic deformation, which consists of making a metal through an array, an everyday example of this process is the toothpaste: pressing the container and eject the pasta through the mouth of the same, are generating a process of extrusion.

In the case of the aluminum process consists of heating the same in a controlled manner prior to its entry into the extrusion press, in which through the application of high pressure is made to flow aluminum through a mold or die that determines the final shape of the product.

Like toothpaste, aluminium is not liquid, if he does not behave as a malleable solid during extrusion.

What is the anodizing?

Anodizing is an electrolytic process which forms a layer of protection on the surface of the aluminum base known as "alumina" or aluminium oxide (Al2O3). This layer is formed due to the passage of an electrical current in an electrolyte acid, taking aluminum as anode. According to the thickness of this layer gets higher strength and durability to external agents (water, saline environments, UV rays, etc.).

This result, coupled with the aesthetic finish achieved with anodized, opens endless possibilities of application products and commercial and industrial components.

Features additional aluminum

Properties:
Availability of colors:

Architectural finishes for anodized aluminum are limited to certain colors, including black, champagne and traditional bronze tones.

Aesthetics:

Anodized offers wide range of shades, colors and textures of glossy or matte, thus is satisfied demanding and varied customers tastes. Unlike other finishes, anodised aluminium allows to keep the metallic appearance of the material.

The Anodic layer is translucent, this allows to observe the metal base aluminum giving an appearance of metal surface far superior to that can be achieved with organic paints.

Security:

An anodized finish is chemically stable. It does not decompose, it is non-toxic. It is not fuel below the degree of fusion of aluminum: 660 ° c, providing a high degree of security.

Recyclable:

The anodized non process alters the recyclable properties of aluminum.

Electrical insulation:

It has insulating qualities with a voltage breakdown of 500-600 V at a thickness of 12-15 microns.

Application of anodized aluminum.

  • Architectural structures: walls curtain, systems, roofs, windows, awnings, doors, window frames, accessories, bathroom, etc.
  • Appliances.
  • Exterior and interior of buildings.
  • Sports items: golf carts, camping and fishing.
  • Nautica.
  • Parts for electric motors.
  • Furniture.
  • Automotive and aeronautics.
  • Aerospace industry: protection and marking of satellites by the resistance to UV rays.
