In depth information about aluminium

Aluminium is a silvery white member of the boron group of chemical elements. It has the symbol Al and its atomic number is 13. It is not soluble in water under normal circumstances. Aluminium is the most abundant metal in the Earth’s crust, and the third most abundant element, after oxygen and silicon. It makes up about 8% by weight of the Earth’s solid surface. Aluminium is too reactive chemically to occur in nature as a free metal. Instead, it is found combined in over 270 different minerals. The chief source of aluminium is bauxite ore.

Aluminium is the most widely used non-ferrous metal. Global production of aluminium in 2005 was 31.9 million tonnes. It exceeded that of any other metal except iron (837.5 million tonnes). Forecast for 2012 is 42–45 million tons, driven by rising Chinese output. Relatively pure aluminium is encountered only when corrosion resistance and/or workability is more important than strength or hardness.

Aluminium is a soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Aluminium is nonmagnetic and non-sparking. It is also insoluble in alcohol, though it can be soluble in water in certain forms. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.

Aluminium is remarkable for the metal’s low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are very important in other areas of transportation and building. Its reactive nature makes it useful as a catalyst or additive in chemical mixtures, including ammonium nitrate explosives, to enhance blast power.
Corrosion resistance can be excellent due to a thin surface layer of aluminium oxide that forms when the metal is exposed to air, effectively preventing further oxidation. The strongest aluminium alloys are less corrosion resistant due to galvanic reactions with alloyed copper. This corrosion resistance is also often greatly reduced when many aqueous salts are present, particularly in the presence of dissimilar metals.

Aluminium is 100% recyclable without any loss of its natural qualities. Recovery of the metal via recycling has become an important facet of the aluminium industry. Recycling involves melting the scrap, a process that requires only 5% of the energy used to produce aluminium from ore, though a significant part (up to 15% of the input material) is lost as dross (ash-like oxide). The aluminum dross can undergo a further process by aluminum dross processing machine to extract aluminium.

Aluminium metal can be used in:

1 Construction (aluminium windows, aluminium door, aluminum profiles, aluminum extrusion, aluminum alloy,siding, building wire ETC)
2 Transportation (automobiles, aircraft, trucks, railway cars, marine vessels, bicycles etc.) as sheet, tube, castings etc.
3 Packaging (cans, foil, etc)
4 A wide range of household items, from cooking utensils to baseball bats, watches.
5 Street lighting poles, sailing ship masts, walking poles etc.
6 Outer shells of consumer electronics, also cases for equipment e.g. photographic equipment.
7 Electrical transmission lines for power distribution
8 Super purity aluminium (SPA, 99.980% to 99.999% Al), used in electronics and CDs.
9 aluminium Heat sinks for electronic appliances such as transistors and CPUs.
10 Substrate materials of metal-core copper clad laminates used in high brightness LED lighting.
11Powdered aluminium is used in paint, and in pyrotechnics such as solid rocket fuels and thermite
12 Aluminium can be reacted with hydrochloric acid to form hydrogen gas.


Aluminum dross generated from aluminum melting furnace and aluminum dross processing machine

Aluminum dross generated from aluminum melting furnace and aluminum dross processing machine

Aluminum dross is a mass of solid impurities floating on a molten metal.  As aluminum metal melting point is 660℃, which is low-melting-point, so it will be formed on the surface in aluminum melting or alloys by oxidation of the aluminum.

In the factory, aluminum dross generated from aluminum melting furnace is about 600 tons per month,  the aluminum  content in aluminum dross is about 40-75%, so it is very important to increase aluminum recovery rate from aluminum dross, which will effect the profit magin in the aluminum melting and aluminum extrusion.

We compare dross processing methods and we use high efficiency and environment-friendly aluminum dross processing machine for the dross recovery in aluminum melting workshop and the recovery rate  is satisfied.   The economic benefits is great and we got the feedback from the accouting department.

Here is the advantages of the aluminum dross processing machine with the aluminum dross cooling system in  aluminum melting factory

High efficiency for recycling rate (90% of aluminum from the ashes), short working time (10-12 minutes for finish the separation of 200kgs-650kgs aluminum and dross)

★Small investment, big processing capacity.  500kgs-2,600kgs aluminum dross processing capacity per hour.

★Low production cost

★No pollution. Cyclone dust collector can avoid the pollution and meet the requirement of environment protection

★Make full use of aluminum dross.  The aluminum processed from aluminum dross can be used for the melting. Aluminum dross can be used as the materials of aluminum chloride series reagent. Or aluminum dross can be sold to the subcontractor for the further processing or aluminum dross can be joint materials that replaced ice stone for the raw materials of Electrolytic aluminium.

★making improvement based on imported foreign advance technology (add crushing function and sieving function)

★High degree mechanization; good cooling and sieving in grade function

★Convenient for the central dust collecting (the buyer needs to provide environmental-friendly dedusting device)

★Sturdy structure and long using life

Aluminum profiles for the automobile industry

The proportion of aluminum is only 2.79g/cm3, which is less than half of steel (7.6g/cm3) and copper (8.5g/cm3). As an ideal lightweight material, the potential advantages of aluminum are getting clearer and clearer. The application of aluminum in transportation system not only reduces weight and improves the fuel efficiency, but also cuts greenhouse gas emissions.

Aluminum tile trims

Aluminum tile trims and aluminum extrusion profiles


Aluminum Tile trims are aluminum extrusion pofiles for the tiling, which is useful to protect the edges of your tiles and also support and protect them. The tile trims also safeguard the tiles from chipping or cracking at the edges due to pressure. Also metal tile edging is used to prevent intense pressure from breaking the tile especially at the dividers between ceramic tiles and the walls. The tile trims also help to provide an aesthetic look to the tiled floor bottom. They could be straight or round and are made of high quality materials.
