Rolling begins with preheated aluminum sheet ingots that can weigh more than 20 tons. As the size of rolling mills has increased, so has the size of these ingots, but a typical ingot is approximately 6 feet wide, 20 feet long and more than 2 feet thick. The ingot is first heated to rolling temperature and fed into a breakdown mill, where it is rolled back and forth until the thickness has been reduced to just a few inches. The slab can be subsequently cold rolled or may be heat-treated to increase its strength. The highest strength alloys are heat treated and rapidly cooled to room temperature, after which they are stretched to straighten and relieve internal stress built up during rolling and heat-treating. They are aged naturally at room temperature or artificially aged in a furnace to develop the desired combination of strength and corrosion resistance. Finally, the plate is trimmed to final size. Plates produced in this manner may be used at full thickness, but are often machined into a variety of simple to complex shapes.
Aluminum sheet 6061 T4 is used in many types of industrial applications, including: Aircraft panels Automotive panels Trailer frames Packaging And more
Aluminum 2014 is a precipitation hardening alloy with fair corrosion resistance, high electrical conductivity, and good machinability. As one of the strongest aluminum alloys on the commercial market, 2014 Aluminum is heavily used in the manufacture of aircraft and truck parts, as well as in forging applications. 2014 alloy is primarily aluminum based, with copper being the other major element. Standard specifications for 2014 include ASTM B209, UNS A92014 and more.
