Aluminum flat-rolled products

Rolled aluminum is mainly flat products: thick sheets (plates), thin sheets and foil. It is flat rolled aluminum - sheets and foil - that make up about half of all aluminum products, for example, in the United States. More flat aluminum products are produced, than such types of aluminum products, like aluminum castings, extruded profiles, aluminum wire, aluminum rods, and also forged aluminum, stamped and powder products.

Classification of flat aluminum products

All three types of flat aluminum rolled products are rolled to a rectangular cross section. They differ only in thickness:
– aluminum thick sheet;
– aluminum thin sheet and
– aluminum foil .

Aluminum thick sheet

Aluminum thick sheet, abroad - aluminum plate (plate), called aluminum, rolled to thickness: more 6,3 mm (quarter inch) in the US or more 6 mm - in Europe and other countries with metric system. Aluminum thick sheet can have scissor or saw cut edges. Thick sheet is usually produced in flat form, but sometimes in bays.

Properties and applications of aluminum thick sheets

Thick aluminum sheets - aluminum plates - are used to make various strong shapes with the same thickness. They also serve as blanks for machining complex flat parts., such as ribbed panels for aircraft wings. They are easily welded into large, robust and durable structures.

Other numerous uses for thick aluminum sheets include:
– railway and road tanks;
– aluminum armor for tanks and other armored vehicles;
– deck structures of large commercial and military ships;
– offshore oil storage;
– tanks for the transportation of liquefied natural gas;
– supporting structures of airplanes and spaceships.

Aluminum thin sheet

Sheets less than 6,3 mm (6 mm) and up to a thickness of at least 0,20 mm called thin sheets, and abroad - just sheets (sheet).

The edges of thin sheets can also be cut with a saw and scissors. They are supplied as flat, and in bays. Some manufacturers of thin aluminum sheet perform additional operations with it., such as coloring or texturing. Previously, thin sheets were called sheets up to 0,15 mm.

Properties of aluminum thin sheets

Aluminum thin sheet is an amazingly versatile material. And not only that, which can have exactly those characteristics and properties, which the consumer needs, but also so, well suited for various types of outdoor decoration, processing and connection methods.

Aluminum sheets can be applied to a wide variety of exterior finishes:
– applying a volumetric pattern;
– liquid coloring;
– electrolytic coating;
– polishing;
– powder coating;
– lamination;
– anodizing;
– etching;
– texturing.

Aluminum sheets lend themselves to various machining methods:
– cutting;
– sawing;
– drilling.

It is easy to shape aluminum sheets by:
– flexible;
– corrugation;
– hoods;
– punching.

Aluminum sheets are easily bonded to each other or other materials in a variety of ways:
– riveted;
– on bolts or screws;
– fold;
– solid soldering;
– soft soldering;
– welding;
– adhesive bonding.

Application of aluminum thin sheets

The application list of aluminum thin sheets is too wide, so that you can list it in full. It includes such familiar products, as:
– aluminum bases of electric bulbs;
– aluminum cans for soft drinks ("beer cans") and food;
– aluminum kitchen utensils;
– Appliances;
– awnings;
– jalousie;
– aluminum siding for house facades;
– aluminum roof;
– aluminum drainage systems;
– building envelopes: windows, doors and curtain walls;
– road signs;
– car license plates;
– heat exchangers;
– parts and upholstery of cars;
– truck panels, trailers and buses;
– plating of boats and aircraft.

Aluminium foil

Ordinary aluminum foil is flat rolled aluminum with a thickness 0,20 mm. Such foil is supplied as in coils, and flat. The thickness of the special - thin - foil can reach 6,5 m.

Properties and applications of aluminum foil

Aluminum foil is familiar to many people from the popular kitchen foil.. It is easy to wrap any food in this foil, it does not allow water and steam to pass through. Foil does not burn, conducts heat well and reflects it well. Housewives love foil also for that, that mold never grows in it.

But there is also other foil - made of harder and stronger aluminum alloys, whose strength may approach the strength of steel.

The variety of properties of aluminum foil makes it indispensable for protective packaging of products, medicines and other consumer goods, to foil-laminated building films for steam- and wind insulation of buildings, artificial christmas trees, rigid packaging containers and honeycomb building materials.
