![]() It has a melting point of 660°c and a boiling point of 2470°c. It is located in Group 13 as a metallic solid at room temperature, it is relatively light weight and strong. Whilst Aluminium has been known as the compound Alum (a sulfate salt of Aluminium) since the 5th century and during the Middle ages it was not until 1825 that the Danish physicist Hans Christian Ørsted managed to isolate the metal from its ore. ![]() Aluminium whilst strong is most commonly alloyed to other metals to increase its strength and still maintain its light weight properties. The powerful all-new tweeter and 6th-generation ceramic-coated, cast-aluminum Acoustic Lens waveguide seamlessly integrate with the directivity of the companion midrange driver resulting in greater efficiency, improved dynamic range, reduced distortion, and increased power handling compared to aluminum or titanium tweeters. Its most common use is in the construction of cars and aircraft. Aluminium is most commonly used in construction and containers as it is lightweight and strong. Aluminium is extracted from Bauxite using electrolysis as it is more reactive than Carbon. Sign Aluminium with atomic number and atomic weight. Name: aluminium Symbol: Al Atomic number: 13 Relative atomic mass ( Ar): 26. abstract vector science concept background polygonal geometric. Used as alloy, for transportation, packaging, machinery, cases and in electricity. Chemical element and metal with symbol Al and atomic number 13. It is found in the earth’s crust bonded to oxygen in the ore Bauxite. Aluminum, aluminum on periodic table of the elements. It has the symbol Al.Īluminium makes up 8% of the earth’s land mass and is a relatively abundant metal. Aluminium (Al) is a silver coloured metal often tarnished by oxidation that has the atomic number 13 in the periodic table.
