Introduction
Aluminum metal has revolutionized the metal industry. Do you know why? Because of the endless benefits and properties of shaping and manufacturing many materials. Above all, there is no risk of corrosion, unlike with iron or other metals.
Sometimes, it is 100% necessary to know the aluminum metal melting point. In this guide, we will discuss all the Aluminum alloys and describe the temperature for melting aluminum.
Let’s have a detailed discussion.
What is the Melting point?
A metal is most often in a solid state. At this point, it is tough to change its form and shape it into other materials. The melting point is the temperature that helps convert the solid metal into liquid form.
Whenever the melting temperature reaches, the solid becomes liquid. Every solid item produced by nature has a specific melting point upon which it gets converted into liquid form.
What temp does aluminum melt?
Aluminum is a rigid metal. That is why it has a higher melting point. In its pure form, aluminum’s melting point is 660.32 degrees Celsius( 1220.58°). In contrast, the boiling temperature of aluminum is 2467.
On the other hand, aluminum oxide has a very high melting point of up to 2000 degrees.
Today, in industry, the melting point of metals is very critical. However, aluminum is almost always mixed with alloys. Metal engineers create aluminum metal alloys to change their melting and boiling points. The difference in alloy composition results in a different melting point than pure aluminum.
We will discuss the alloys in detail.

Why is the Aluminum Melting point essential to know?
Sometimes, the metal workers want to know the impurities. Since the aluminum metal melting point is a physical property, it will show the amount of impurities.
For instance, pure aluminum melt temp is 660 degrees Celsius. In the case of impurities, it will either increase or decrease. The result will be quickly melting. That is how the metal workers estimate the purity. One more thing is the nature of the application in which you are going to use Aluminum.
Sometimes, aluminum alloys work perfectly. Melting temperature will determine whether it is pure aluminum or which alloy you are holding in your hands.
Factors that affect the Aluminum metal melting point
Aluminum melt temp depends mainly on the components. For instance, if you have pure aluminum, it will have a different melting point. In the case of a covalent bond, it will need more energy to break the molecules. Therefore, the melting temperature will be higher.
Here are some of the critical features of the aluminum metal melting point.
Alloy compound
Alloy is the combination of multiple metals. Aluminum has alloys with other metals, such as copper, magnesium, etc.
The sole reason behind doing so is to increase the features and get the desired results from the metal.
Does it impact the melting point?
Yes. Alloy compounds might have a high or sometimes low Aluminum melt temp compared to pure metal. So, alloy compounds are one of the massive factors affecting melting points.
Chemical impurities
Alloy is sometimes deemed as an impurity since pure aluminum is not there. But it is not an impurity because an impurity is:
A metal or particles present in the compositions that are not essential.
In contrast, alloys have metals that are intended. Most often, chemical impurities do a phenomenon called melting point depression. Impurities decrease the melting points. Any melting point changes over 41 degrees Fahrenheit depression indicates the chemical impurities.
Contamination during casting and melting of the aluminum can occur. Therefore, sometimes Aluminum has a lower melting point due to impurities.
Bond among molecule
Whatever metal or alloy you have in your hand has bonds among the molecules holding it together. Sometimes, it can be an ionic bond and a covalent bond.
So, what bond is the strongest?
A covalent bond has the maximum strength and requires more energy to break. That means if molecules have a covalent bond, it will require more energy to break and melt them. So, the bond is an influencing factor for the melting point.
Force of Attraction
The force of attraction between the molecules also increases the melting temperature. If the force of attraction is high, aluminum will have a high melting temperature.
Aluminum has a polar bond increases the melting point to 660 degrees Celsius.
Pressure
Pressure application is quite common in metal fabrication. It can impact the melting point. A pressure of up to 3500 gigapascals can increase the melting point.
If you cross this pressure range, the melting point will drop and lead to lower melting points.
