Aluminum is a chemical element which is found in the Boron group. Its symbol is “Al” and it has an atomic number of 13. This is a metal that is silvery-white, soft, and non-magnetic and a ductile metal. One of the most abundant metals after oxygen and silicon is aluminium and it’s the most abundant metal in the earth crust. It adds up about 8% of the total weight of the Earth’s solid surfaces. The main ore of Aluminum is Bauxite.
Aluminum is not mixed with Diamond to form the aluminum diamond plate. The Aluminum has many useful properties that contribute to the outstanding nature of the aluminum diamond plate – you can buy some here. These include:
- Excellent Corrosion Resistant
The resistance to corrosion of aluminium is usually good this is because of a thin surface layer of aluminium oxide which is formed aluminium plates are exposed to the oxygen which in turn prevents further oxidation to occur. The resistance in corrosion is also mostly reduced by aqueous salts, particularly when dissimilar metals are available
Aluminum can react in highly acidic conditions whereby it will react with water so as to form hydrogen and alkaline to form aluminates.
Because of this resistance to corrosion aluminum is one of the metal that will be able to retain its silvery reflectance in finely powdered form.
- Electrical and Thermal Conductivity
Aluminium is one of the good and excellent conductors of both heat and electricity. The goodness of aluminium is that of its weight, and also it has a greater conductivity than copper. Therefore, aluminium is one of the commonly used metals in large transmission lines. The Aluminum plates can be used for all electrical conduction and domestic activities including domestic power.
Aluminium is also able to be a super conductor with a superconducting temperature of 1.2Kelvin and also has a magnetic field of 100gaus. This characteristic will make aluminum a great metal for use other than other metals available.
- Strength to Weight Ratio
Aluminum metal has a density which is one third that of steel and therefore aluminum is usually used where a metal with high strength and low weight is needed.
Pure aluminium will not have a tensile strength than alloys in that alloying will really help in increasing the strength property of aluminium which will be suitable for a certain task to be done. Unlike other metals, aluminum does not become brittle and instead its strength will increase.
Aluminum strength will decrease at high temperatures and at a temperature above 100 c strength affected to an extent that its start to weakens.
One of the best characteristic of aluminium is that it has a lesser weight and a lesser density that steel which is much heavier and has a higher density. The lowness in density will help in bringing about the light weight but it will not really affect the strength of aluminium. Aluminum has a strength which ranges between 70 MPa and 700 MPa.
In conclusion aluminium is the second and most widely used metal in the earth crust. The discussed properties of aluminum which include among many others: low density and this will bring about to low weight of aluminum, high strength, excellent corrosion resistant and also good thermal and electrical conductivity are amongst some of the characteristics which make aluminum become one of the most important metal in the world.
