Advantages of aluminium
Aluminum is the third most common element. About eight percent of the Earth crust consists of aluminium. It is extracted from bauxite, which is mined in open pit mines mainly around the equator.Brazil and Jamaica are two of the most important countries in the world when it comes to extracting Bauxite, but also in Europe, in e.g. Hungary and in the Balkans bauxite is extracted.The aluminium oxide is produced from bauxite at the oxide plants, these plants are located in close proximity to the open pit mines, the aluminum oxide is then processed at the primary plant where pure aluminium is extracted.
Almost every construction problem can have a simple solution: Aluminium profiles. Aluminium can be used instead of steal, copper, plastic or wood.The material is easy to form and the final products has low weight, high strength, high surface finish and with a high corrosion resistance. The tooling costs are reasonable, the technical limitations are few and the possibilities are almost endless.
About smelting plants
About 50% of the aluminium used in our products comes from recycled aluminium. Our suppliers use both internal and external aluminium scrap to reuse in their own smelting plants.
Despite a growing bauxite extraction there is no shortage of raw material since bauxite is formed about 50 times faster than it is extracted.Research has shown a number of benefits using aluminium instead of other materials, this can be an explanation of the rapid market growth.
Easy to form
Aluminium is a soft material which makes it easy to shape, but through the usage of different alloys aluminium can also provide almost the same strength as many steel structures.The material is easy to work with and can be welded, soldered and glued, it has great corrosion resistance and also a high surface finish.
With a weight of 2.7 kg/dm3, aluminium weighs onlya third of steel. The interest and the usage of aluminium is growing, not least in the car- and transport industry which strives for lighter designs to reduce fuel consumption.
Reduced energy consumption
It’s true that relatively high energy consumption is needed in the primary production of aluminium, around 16 000 kWh/ton. This problem is manageable however since the primary production plants are located in regions with a surplus of energy.However, new production methods has shown that it is possible to reduce the energy consumption in the primary production to around 10 000 kWh/ton.
Today the recycling of aluminium is well developed and the remelting of aluminium requires only 5% of the energy consumption compared to primary production of aluminium.The recycling of aluminium can be done as many times as you need, without deteriorating the quality of the material.
