The history of aluminium industry

Humankind came across aluminium long before the metal we know today was produced The Natural History by Pliny the Elder a Roman scientist told the story of a first century craftsman presenting a cup made of an unknown metal looking like silver but too light to be sliver to Tiberius the Roman Emperor Alum an aluminium-based salt was used extensively in ancient tim...

How Aluminum is Produced

Aluminum is formed at about 900 176 C but once formed has a melting point of only 660 176 C In some smelters this spare heat is used to melt recycled metal which is then blended with the new metal Recycled metal requires only 5 per cent of the energy required to make new metal...
