Rolling begins with preheated aluminum ingots that can weigh more than 20 tons. As the size of rolling mills has increased, so has the size of these aluminum  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. aluminum Plates produced in this manner may be used at full thickness, but are often machined into a variety of simple to complex shapes.

Aluminum plate applications

Aluminum Plate is used in heavy-duty applications such as those found in the aerospace, military and transportation product manufacturing. Aluminum plate, machined to shape, forms the skins of jets and spacecraft fuel tanks. It is used for storage tanks in many industries, in part because some aluminum alloys become tougher at supercold temperatures. This property is especially useful in holding cryogenic (very-low-temperature) materials. aluminum Plate is also used to manufacture structural sections for railcars and ships, as well as armor for military
