Aluminium is everywhere, and the applications for this element are many. You may not always be conscious about aluminum presence, but you would definitely miss it.

Mechanical properties

  • Atomic number: 13

  • Melting point: 660.37°C,
  • Boiling point: 2,467°C,
  • Specific gravity of 2.6989 (20°C),
  • Valence: 3.
  • Nonmagnetic and non-sparking
  • Easily formed, machined, or cast
  • First made: In 1825 by the Danish scientist Hans Oersted

Here are some of aluminium’s finest attributes:


Huge Resources

  • Most abundant element in the earth’s crust, after oxygen and silicon
  • Today, bauxite is the only commercial ore used for production of aluminium. In the future, we might have more sources for aluminium
  • With today’s aluminium production, the bauxite reserves will last more than 100 years


Strong & Light

  • 2.7 (g/cm3) = 1/3 the weight of steel
  • Low weight means reduced energy consumption in transportation
  • Low weight is an advantage during assembly in buildings and in many other applications.


Perfect for food packaging

  • Aluminium foil is completely impermeable – no taste, aroma or light gets in or out
  • Widely used in food and drink packaging
  • Efficient conservation of food reduces wastage
  • Low weight reduces packaging in transportation
  • Impermeability also reduces cooling needs


  • Aluminium in buildings, construction and transport is fire-proof
  • Will only burn if shaped as very thin film
  • Will melt at 660° C without releasing any gases

Easy to form

  • Aluminium is ductile and has a low melting point
  • Easy to process in cold and hot condition
  • This allows design flexibility and integration in advanced transport and building industries

Superconductor for heat and electricity

  • Twice as good a conductor as copper
  • This makes aluminium the best choice for energy-efficient systems for electrical transmission, such as transfer components

Great reflector

  • Can reflect both heat and light
  • Combined with its light weight, this makes aluminium ideal for reflectors like light fittings
  • High energy efficiency in the reflectors reduces energy consumption

  Long life – low maintenance

  • Aluminium forms a protective oxide coating that makes it highly corrosion resistant
  • This prolongs the life of aluminium in cars and buildings
  • Reduces need for maintenance
  • Reduces environmental impacts due to replacements and maintenance


Easy to Recycle

  • Re-melting of aluminium requires little energy; total loss in the re-melting process is less than three percent
  • Only five percent of the energy required to produce the primary metal initially is needed in the recycling process
  • About 75 percent of all aluminium ever produced is still in use


Let’s find answers to your most significant questions about online pharmacy. What medications do patients buy on the Internet? In definite instances doctors offer to patients Viagra. Topics such as “” or “cialis generic” are very popular now. It could be that you read about “tadalafil“. Also, think about “tadalafil online“. Sexual heartiness troubles can ordinarily indicate serious problems elsewhere. Some medicaments are not suitable for folk with several conditions, and betweentimes a cure may only be used if extra care is taken. Your pharmacist may on occasion change your dose to be aware you get the best results.
