2018-10-17 Discovery Compared with other metal elements we discussed about before, Aluminum is discovered much later. In 1808, the British chemist Sir Humphry Davy confirmed the existence of alum and named the substance to Alumium (later changed to Aluminum). In 1825, Danish chemist and physicist Hans Christian Ørsted began experimenting about aluminum extraction.
预计阅读时间：3 分钟The Bayer process. While working at the Tentelevsk factory in St. Petersburg, Carl Josef Bayer, an Austrian chemist, invented a method for extracting alumina—aluminium oxide Al2O3—from alkaline solution. Today 90% of alumina in the world is produced by the Bayer process. April 1889.
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 times.
2020-5-30 1050 aluminum is a 1000-series aluminum alloy: it is considered commercially pure, and is formulated for primary forming into wrought products. 1050 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-1050. A91050 is the UNS number. Additionally, the EN chemical designation is Al99,5.
