What are  the Properties of Aluminum? Definition of Aluminum
What is the definition of Aluminum? It is a silvery-white, ductile metallic element, the most abundant in the earth's crust but found only in combination, chiefly in bauxite. Having good conductive and thermal properties, it is used to form many hard, light, corrosion-resistant alloys.

The Physical and Chemical Properties are the characteristics of a substance, like Aluminum, which distinguishes it from any other substance.  Most common substances exist as States of Matter as solids, liquids, gases and plasma. Refer to the article on Aluminium for additional information and facts about this substance.

Aluminum Properties - What are the Physical Properties of Aluminum?
What are the Physical Properties of Aluminium? The Physical properties of Aluminum are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Aluminum are as follows:

  • Color : Silvery-white with a bluish tint
  • Hardness : The pure metal is soft, but it becomes strong and hard when alloyed
  • Ductility : It can be beaten into extremely thin sheets
  • Malleability : Capable of being shaped or bent
  • Conductivity : Good electrical and heat conductors
  • Corrosion : Resists corrosion by the formation of a self-protecting oxide coating

Aluminum Properties - What are the Chemical Properties of Aluminum?
What are the Chemical Properties of Aluminum? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Aluminum are as follows:

  • Chemical Formula : Al
  • Occurrence : Occurs only as a compound, principally in bauxite
  • Oxidation : In moist air, it combines slowly with oxygen to form aluminum oxide
  • Reactivity with acids : Reacts with many hot acids
  • Reactivity with water : Reacts quickly with hot water
  • Reactivity with alkalis : It reacts with Alkalis such as Sodium hydroxide and limewater
  • Compounds: A mixture of aluminum, oxygen and other elements produces Bauxite. Bauxite is an aluminium ore and is the main source of aluminium
  • Alloys : When combined with elements such as copper, silicon, or magnesium it forms alloys of great strength
