    burn aluminum with a jet burner
    Aluminum is a chemical element. The symbol for aluminum is Al, and its atomic number is 13. Aluminum is the most abundant metal. Aluminum is not a type of heavy metal, but it is an element that makes up about 8% of the earth's surface and is the third most abundant. Aluminum is found in food additives, antacids, buffered aspirin, astringents, nasal sprays, antiperspirants, drinking water, car exhaust, tobacco smoke, aluminum foil uses, cookware, cans, ceramics, and fireworks.
    Aluminium is a good electricity conductor. Light and strong. It is also a good conductor of heat. It can be forged into sheets, drawn into wire and extruded into bars of various cross sections. Corrosion resistant.
    Alumunium used in many things. Most of it is used in high-voltage cables. Also widely used in window frames and airframes. Found in homes as pots, soft drink bottles, milk bottle caps etc. Aluminum is also used to coat car headlights and compact disks.
    History
    In the 19th century, before the invention of the electrolysis process, aluminum could only be obtained from bauxite by the Wöhler chemical process. Compared with electrolysis, this process is very uneconomical, and the price of aluminum in the past far exceeded the price of gold. Once considered a precious metal, Napoleon III of France (1808-1873) served his first guests with aluminum plates and his second with gold and silver plates.[4][5] In 1886, Charles Martin Hall of the United States (1863-1914) and Paul L.T. Héroult of France (1863-1914) invented the electrolysis process that has hitherto made aluminum production economical.[4]

    Hardness is the combination of various properties contained in a material that prevents a deformation of the material when a force is applied. The hardness of a material is influenced by elasticity, plasticity, viscoelasticity, tensile strength, ductility, and so on. Hardness can be tested and measured by various methods. The most common are the Brinnel, Vickers, Mohs, and Rockwell methods.
    The hardness of pure aluminum is very small, which is about 65 on the Brinnel scale, so even a little force can change the shape of the metal. For applications requiring hardness, aluminum needs to be alloyed with other metals and/or thermally or physically treated. Aluminum with 4.4% Cu and quenched, then stored at high temperatures can have a Brinnel hardness of 135.
