facts about aluminium

• aluminium has characteristics that makes it an exciting and multifaceted construction material within many areas and it is easy to process with most machining methods such as milling, drilling, cutting, bending, water cutting, laser cutting, turning, tumbling, painting, anodizing and screen printing.
• aluminium is with its light weight and its extreme strength properties the optimal material within multiple areas, such as aircraft construction, the automotive industry, the construction industry, the furniture industry and the packaging industry et cetera.
• aluminium can be alloyed with other chemical elements which produces a broad sortiment of different alloys that has different characteristics; alloys that are common are namely iron, silicon, zink, copper, manganese, magnesium et cetera.
• aluminium can be rolled into sheet, strip and very thin foil, a rolling process changes the properties of the metal and it becomes both tougher and stronger.
• aluminium can be cast into various shapes and sizes.
• aluminium is extruded at a temperature of 500 celsius under high pressure through a tool to produce the desired aluminium profile.
• aluminium is hot-pressed to create material that can withstand high loads.
• aluminium is joined together by welding, gluing and screwing etc.
• aluminium is by far the most common metal in the earth’s crust and our third most common element after oxygen and silicon; aluminium makes up 8% of the weight of the earth’s crust.
• aluminium exists as primary and secondary aluminium; primary aluminium is produced from bauxite which is a very common type of soil that we almost have infinite amounts of and secondary aluminium is produced from recycled aluminium scrap.
• aluminium produced through recycling requires 5% less energy in comparison to the energy required to produce aluminium from bauxite; aluminium is 100% recyclable without the metal losing any of its natural properties, and it can be recycled an infinite number of times.

history

aluminium has a very short history in comparison to other metals.

• humphrey davy was an englishman who lived between 1778-1829; he extracted potassium and sodium electrolytically and named the element he was looking for in clay as aluminium even before he managed to produce it – aluminium was changed a little like other elements to aluminium.
• christian Ørsted, a Danish physicist, was the pioneer who managed to find a direct route from aluminium oxide to metallic aluminium.
• fredrich wöhler was a german chemist who claimed to be the first to produce metallic aluminium; in 1827 he described the properties of the metal and in 1845 he reported improvements in his production method.
• h sinte-claire deville was the frenchman who in 1854 succeeded in a technically useful method for the production of the new metal aluminium; in 1855, the new method of extracting aluminium ingots was demonstrated at the world exhibition in Paris, and the french emperor napoleon III called for further development because he was interested in the metal for army use.
• the year 1886 is the year that counts as the birth year of the modern aluminium industry.
