What is the Aluminum Melting Point?

Aluminum is a metal found in the second row and group 13 in the periodic table. It is the third most abundant element after oxygen and silicon are found in the earth’s crust. Aluminum occurs naturally in compounds but never as a pure metal. The process of extracting aluminum from its compounds is a complex and rather difficult process. Aluminum is a useful and common metal that is known to be light, its malleability and corrosion resistance. Aluminum tends to be easier to recycle than to purify from minerals. It is also quite safe when it comes into contact with the skin and is used around food.

What is the melting point of aluminum?

The melting point of a substance is defined as the temperature at which the substance changes from a solid to a liquid state, but at a specific atmospheric pressure. It is at the melting point that the liquid and solid states of a substance exist in equilibrium. However, the melting point of a substance depends mainly on the pressure; it is often specific to a standard pressure in reference materials. The melting point of a substance is also referred to as a liquidation, liquefaction or solidus point. The melting point of aluminum is 659 degrees Celsius or 1218 Fahrenheit.

What is the purpose of determining the melting point of a substance?

The melting point of a substance is an essential physical property. The main objective of determining the boiling points and melting points of substances during a laboratory experiment is to use the results to help identify impurities in those unknown substances or substances. A melting point of an unknown solid can be used to identify it by comparing it with a variety of other solid potentials and their melting points thus creating a match to identify the solid. Furthermore, the purpose of knowing the melting point of a substance is to use its melting point range to help determine its general purity. In this regard, the greater the fusion range of the substance,

Factors that influence the melting point of substances

The melting point of a substance varies from one substance to another. For example, while oxygen melts at 218 degrees Celsius, the ice melts at 0 degrees Celsius and the aluminum is 219 degrees Celsius. Therefore, some things affect the melting points of different substances. Factors that influence the melting point of substances include intermolecular forces, changes in the melting points of ionic bonds, the shape of molecules and the size of molecules. A pure compound that is crystalline usually has a more precise melting point so it completely melts over a small temperature range not exceeding 0.5-1 degrees Celsius. If such a substance also contains the minimum amount of impurities, depression is usually produced at freezing points showing an increase in the width of the melting point range. If a melting point range is greater than five degrees, it means that the substance is impure.

The uses of aluminum

Aluminum is one of the most useful metals in the world. In its pure form, aluminum is mainly used by the electronics industry to make hard disks, conductive tracks on silicon chips and capacitor sheets. When the metal is bound to other metals such as silicon, zinc, copper and magnesium, it becomes even stronger. Another significant use of aluminum is in the production of beverage cans and the sheet used to protect food and a variety of kitchen utensils.
