As aluminum passes through the roll under pressure, it becomes thinner and longer in the direction of movement. This simple process is the basis for the production of aluminum sheet, sheet, and foil. Sheet metal is the most widely used form of industrial aluminum and is used in aerospace (aircraft aluminum sheet for skins), transportation (automotive body sheets), packaging (tanks and ends), and construction (building facades).
Moreover, aluminum sheet and plate can be recycled continuously without loss of properties. Recycling aluminum sheet and plate saves more than 90 percent of the energy otherwise required to produce primary aluminum. Marine grade aluminum sheet meets the U.S. marine’s highest performance standards. Aluminum from 0.008 inches to less than 0.25 inches thick is considered sheet. Thinner aluminum is foil and aluminum 0.250 inches and thicker is plate. 7075 aluminum plate is used for storage tanks in many industries in part because aluminum alloy sheet metal gains strength at super cold temperatures.
The production of sheet or foil usually begins in the same manner as the plates, but the sheets are rolled further through a continuous rolling mill to reduce their thickness and rolled into a coil at the end of the production line. These coils are then cold rolled, from one to several passages in the cold mill. The coil can be heated in a furnace to soften it for further cold rolling or to produce the desired mechanical properties. Cold rolling is the final step for some aluminum sheet plates, but other types of plates (called heat-treatable plates) require further high temperature treatment to increase their strength.
Some sheet and foil products can also be produced using the continuous casting process, in which molten metal enters the continuous casting machine to create hot rolled rolls, bypassing the ingot and hot rolling steps.
7050 aluminum plates are used in heavy duty applications, such as those found in aerospace, military, and transportation product manufacturing. The aluminum plates are processed to form the outer shell of the jet and spacecraft fuel tanks. It is used in storage tanks in many industries, in part because some aluminum alloys become harder at supercooled temperatures. This property is particularly useful for preserving low (extremely low) temperature materials. Steel plates are also used to make structural parts for rail vehicles and ships, as well as armor for military vehicles.
2024 aluminum sheet is the most widely used form of aluminum and can be found in all major markets of the aluminum industry. In packaging, sheet is used to make cans and packaging. In transportation, aluminum sheets are used to make car bodies and tractor trailers. Sheets are used for household appliances and cooking utensils. In buildings and constructions, it is made into products, including siding, gutters, roofs, awnings and garages. Aluminum alloy sheet can be colored anodized to black, gold, red, blue and hundreds of other colors. It can be etched to a matte finish, polished to a glitter, or polished to a wood like texture and paint.
Hangzhou Saining Polycarbonate Sheet Co., Ltd. was founded in 1997, a manufacturer that specializes in producing various kinds of high-quality aluminum alloy sheets and plates (such as 5052 aluminum sheet and 6061 aluminum sheet).
