Aluminium

Aluminium is a light metal of silvery-greyish colour, resulting from the fact that in open air it produces a thin layer of oxide that covers it. This layer makes aluminium very much corrosion-resistant. Aluminium is extendible and when rolled it can be turned into a thin foil. Aluminium compounds are widespread but only the exploitation of bauxite with high contents of aluminium oxide to obtain aluminium would be commercially and economically profitable. Aluminium is very plastic, but it could also be forged. As a rule, it is used alloyed with other metals.


About aluminium history
In the year 1886, independently from each other, Charles Martin Hall and Paul Heroult were developing the procedure of aluminium production: later on, it was called the Hall-Heroult aluminium production process. Even today, large and modern plants for aluminium production still apply this procedure. In 1889 Karl Josef Bayer additionally upgraded this procedure.

According to Woehler, metalic potassium is used as the reducing agent. Technically, aluminium is produced by melting in a specific electrolysis procedure (Bayer procedure). This procedure of obtaining aluminium requires a large quantity of energy - the consumption is about 13-16 kWh/kg.


Use of aluminium
Due to its low density, aluminium is very often used when there is a need for a large mass movement, primarily in packaging production, airline industry and astronautics. For the same reason, aluminium is becoming increasingly present in car industry as well. Obviously, aluminium is more very much present in construction, which has become evident in the past few years (production of doors and windows, plastering solutions, production of roof parts, pipes, etc.).

In alloys with magnesium, silicon and other metals, it is possible to obtain great strength of pressed aluminium profiles which are barely lagging behind the steel profiles.  The use of aluminium is particularly favoured in cases where certain products and items need to be reduced in mass. For that reason, aluminium is a particularly popular material in airline industry and in astronautics. Also, aluminium is more and more present in car industry.


About aluminium processing
Different processes are applied in aluminium melting and that enables the production of rolled bars (blocks) or pre-defined shapes. From cast aluminium - with the application of the injection process - it is also possible to produce much more complicated and precise shapes than cast aluminium bars and cast blocks.

Due to its fairly low melting point, some procedures in aluminium processing are very often used in car industry (for production of engine blocks, injection pump casings, and cylinder heads). Because of its very good heat conductivity, aluminium has more advantages in this area than iron.

Aluminium profiles are regularly used in construction industry and they are very much appreciated for their characteristics. They have high quality, ensure adequate strength and loading capacity, while the elements made of aluminium profiles are structurally stable. In addition, aluminium profiles provide heat and sound insulation, air and water resistance and they have modern design.


Copper

Copper - a bright reddish metal, also used for the front sides of buildings, consists of 100 % Cu-DHP. This material is very easily shaped (strip thickness of 0.6-0.7 mm). Its stability and long life have been proven. Due to atmospheric impact, copper forms an oxide layer which changes in colour and structure with time and finally leads to a typical greenish patina (copper carbonate).


Brass

This alloy consists of copper and zinc - CuZu15 in quality. From the original golden red colour, it first develops an initial opaque-greenish colour and later on achieves the final dark brown anthracite colour.

In addition to sheets, depending on the needs, panels, shingles, cassettes and perforated plates are also produced. The material is very convenient for large flat surfaces.
