The Association is a 501 (c) (6) non-profit organization based in Arlington, Virginia, United States. (The Association was based in Washington, D.C. until c. 2005.) Pursuant to seven ANSI H35 standards, The Aluminum Association registers and publishes specifications describing the composition, mechanical properties and nomenclature of aluminum ...
Aluminium recycling is the process in which secondary commercial aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium. [1] It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al 2 O 3) refined from raw bauxite by ...
7005 is an aluminium wrought alloy [1] used in bicycle frames. Due to its relative ease of welding, it does not require expensive heat treating. It is, however, harder to form, making manufacture more challenging. [2] It has an Ultimate Tensile Strength of 350 MPa, a Fatigue Strength of 150 MPa and a density of 2.78 g/cm 3. [3]
In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate ...

Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al 3+ is small and highly charged; as such, it has more polarizing power, and bonds formed by aluminium have a more covalent character.
