As the aluminum passes between the rollers under pressure, it becomes thinner and longer in the direction of travel. This simple process is the basis for the production of aluminum sheet, sheet and foil. Sheet is the most widely used form of industrial aluminum and is used in applications such as aerospace (aircraft skins), transportation (automobile body panels), packaging (can bodies and ends) and construction (building facades).

Boards and boards can be recycled continuously

Sheet and sheet aluminum can be recycled continuously without loss of properties. Recycling aluminum sheet and sheet saves more than 90% of the energy needed to produce primary aluminum.

"Gauge" of aluminum sheet and foil from 0.008 inch to less than 0.25 inch thick is considered sheet. The thinner aluminum is foil and aluminum 0.250 inches, the thicker is plate.

Colder, stronger aluminum sheets are used in many industries for storage tanks, in part because some aluminum alloys gain strength at ultra-low temperatures.

Production of aluminum plate

Rolling begins with preheated ingots weighing over 20 tons. These ingots increase in size as the mill size increases, but a typical ingot is about 6 feet wide, 20 feet long, and over 2 feet thick. The ingot is first heated to rolling temperature and then fed into a disintegrating mill where it is rolled back and forth until it is reduced to only a few inches in thickness. The slab can then be cold rolled or heat treated to increase its strength. The highest strength alloys are heat treated and rapidly cooled to room temperature, then stretched to straighten and relieve internal stresses created during rolling and heat treatment. They are aged naturally at room temperature or artificially in a furnace to develop the desired combination of strength and corrosion resistance. Finally, the board is trimmed to final dimensions. Plates produced in this way can be used in full thickness, but are often machined into a variety of simple to complex shapes.

From plate to sheet and foil

Production of sheet or foil is generally the same as sheet, but the slab is further rolled through a continuous rolling mill to reduce thickness and wound into coils at the end of the line. These coils are then cold rolled one or more times in cold rolling mills. Coils can be heated in a furnace to soften them for further cold rolling or to develop the desired mechanical properties. Cold rolling is the final step for some plates, but other types (called heat-treatable) undergo further high-temperature processing to increase their strength.

Some sheet and foil products can also be produced using a continuous casting process in which molten metal enters a casting machine to produce hot rolled coil, thereby bypassing the ingot casting and hot rolling steps.

Aluminum application

Sheets are used in heavy-duty applications such as those found in aerospace, military and transportation product manufacturing. Machined and formed aluminum sheets form the skins of jet and spacecraft fuel tanks. It is used in storage tanks in many industries, in part because some aluminum alloys become stronger at ultra-low temperatures. This property is especially useful when maintaining cryogenic (extremely cold) materials. Plates are also used to make structural sections for railcars and ships, as well as armor for military vehicles.

application

Sheet is the most widely used form of aluminum and is found in all major markets of the aluminum industry. In packaging, sheets are used to make cans and packages. In transportation, aluminum sheet is used to make panels for automobile bodies and tractor trailers. Sheets are used in household appliances and cookware. In building and construction, it is made into products including siding, gutters, roofing, awnings and carports. Aluminum sheet can be anodized in black, gold, red, blue and hundreds of other colors. It can be etched to a matte finish, polished to a shimmering brightness or grained to resemble wood and painted.

Aluminum formula

Recipe success may depend on the use of aluminum sheet. Many recipes specifically recommend the use of aluminum sheets and foil, since some bakewares are poor heat conductors and others can discolor some foods. They are known for their even heat distribution and durability.
