The 8000 series aluminium alloy sheet includes alloys of 8011, 8021, 8079, 8090 and 8093. The most popular is 8011 aluminium alloy sheet. The main alloy metal of the alloy sheet is Lithium, which has a significantly lower density than aluminum because its solubility is also relatively high, and it can significantly reduce the density in a sufficient amount of aluminum alloys (usually about 10%, less than other aluminum alloys). Not only causes the alloy to increase its stiffness, but also responds to age hardening. In addition, the resistance to fatigue crack growth increases at intermediate pressure levels. This attractive combination of properties has led to great interest, especially for aerospace applications. These alloys have a high volume fraction of coherent, ordered LiAl 3 precipitation, which is responsible for these properties. For example, the 8011 aluminium alloy is based on Al-Fe-Si, but more than 1% of the total alloying elements give a correspondingly higher advantage.
8011 aluminum alloy sheet is an aluminum sheet whose main function is to make bottle caps. It is also used in radiators, most of which are aluminum foil. 8011 is an 8 series aluminum alloy with si (silicon) content between 0.5-0.8%, fe (iron) content between 0.6-0.9%, and trace elements, the rest is aluminum.
Composition of 8090 aluminum alloy sheet is Si 0.20%; Fe 0.30%; Cu 1.1.6%; Mn 0.10%; Mg 0.1.3%; Cr 0.10%; Zn 0.25%.
The composition of 8079 aluminum alloy sheet is Si 0.05~0.30%; Fe 0.1.3%; Cu 0.05%; Zn 0.10%. 8079 aluminum alloy has high strength, good elongation and spreading pressure, and has the advantages of moisture resistance, air tightness, shading, abrasion resistance, fragrance retention, non-toxic and odorless.
