Aluminium (Al) is metal that has a silver reflective finish. It has similar characteristics with Ferum (Fe / iron) but better for building material purposes. Aluminium is well known for its ability to resist corrosion. It is strong yet lightweight. It also reduces sun exposure into the building.
Aluminium is the most abundant metal on earth. According to the published data by USGS (United States Geological Survey), there are 66 million tons of Aluminium produced by the world countries in 2018. China is the world's biggest Aluminium producer with 33 million tons, followed by India and Russia with 3,7 million tons, Canada with 2,9 million tons, and United Arab Emirates with 2.6 million tons.
Advantages of Aluminium
Aluminium is light, one third the weight of steel.
Aluminium does not rust and can normally be used unpainted. However, the strongest alloys will corrode in some hostile environments and may need protection.
This technique, the standard way of producing aluminium sections, is vastly more versatile than the rolling procedures in steel. It is a major feature in aluminium design.
Most of the alloys can be arc welded as readily as steel, using gas shielded processes. Welding speeds are faster.
Milling can be an economic fabrication technique for aluminium, because of the high metal removal rates that are possible.
The use of adhesive bonding is well established as a valid method for making structural joints in aluminium.
Suitable for cryogenic applications, because it is not prone to brittle fracture at low temperature in the way that steel is. Its mechanical properties steadily improve as the temperature goes down.
In the 1850s-1880s aluminium became the second most important industrial metal. There was a stage when Aluminium was a high cost luxury metal. It was a valuable element that produced products for the nobles. Then in 1886, the electrolytic process was invented for smelting aluminium. It cut down the production cost up to 80- 90% and turned aluminium into a tonnage industrial material.
Aluminium as Building Material
Aluminium is a light, but strong metal, which is resistant to corrosion, non-toxic and also durable. It transforms into desired shapes and attractive visual finishes in building facades and framing. Aluminium allows designers and engineers to create structures and surfaces that cannot be made from other materials such as wood, stone, or steel. Therefore it is so commonly used in contemporary architecture design and modern construction.
