Melting Point of Aluminium

Aluminium is a versatile metal with unique properties that are beneficial in various applications and which become necessary to many industries. Scientists, engineers and fabricators alike take into account one of its central attributes- it’s melting point. Today, we will dive into just what that melting point means to us and some other cool facts about aluminium. If you are interested in some alternative applications of Aluminium these other articles on ALUMINIUM might interest you and you may also get to know Is Aluminium Magnetic or not.

Smart Purchasing: Know the melting Point for Aluminium

What is a Melting Point?

Melting point of any substance is the temperature at which it converts into liquid form. This temperature is essential for manufacturing and engineering processes like casting, welding or extrusion. One of the important parameters for these processes is melting point, which corresponds to properties in metals like aluminium.

Aluminium’s Melting Point

The melting point of aluminium is 660.3…What? Aluminium has a relatively low melting point (660°C) which sees it utilized in a wide range of applications, particularly when compared to other metals such as iron (1538°C) and copper.

Influential Parameters on the Melting Point of Aluminium

Purity of Aluminium

Impurities can significantly lower the melting point of Aluminium. Although, Aluminium itself has a certain melting point that will be lesser in the presence of impurities. Melting point can be changed very slightly by alloying it with small amounts of copper, magnesium or zinc.


Aluminium – melting point range depending on pressure Higher pressures cause an increase in melting point, and lower pressure causes a decrease in the heat needed to melt. This is true, but the shifts are generally very small indeed and only begin to be significant at exceedingly high pressures.

How Aluminium Melting Point Affects Industry

Manufacturing and Fabrication

Since aluminium has a lower melting point than steel, it can be heat-processed by several methods such as casting (pouring into m-old) with less energy. Moreover, Aluminium takes very little time to cool and solidify so the production process is much faster.

Welding and Joining

The melting point is very important in welding. Welding Aluminium alloys, with their great melting points, are handy for the 2 most prominent welding approaches e.g., TIG or MIG. A lower melting point lessens the amount of energy you have to put in and also reduces distortion, defects.


One of the Stand out properties is aluminium’s recyclability It is melt-able, and can be easily re-cycled with little deterioration in quality. As a result of its low melting point, it requires lesser energy to recycle Aluminium than with other metals and thereby makes the project more sustainable.

Melting Points of Aluminium Alloys

Common Aluminium Alloys

Mechanical properties of aluminium can be enhanced considerably by alloying. 6061, 7075 and 2024 are amongst the most common examples of these alloys; each with a specific composition that gives them varying properties. These alloys have melting points a little higher than with pure aluminium.

Melting Point Variations

Aluminium has a relatively low melting point; however, it can change the range of its length according to magnesium and silicon added while alloying. For instance, 6061 aluminium alloy which contains magnesium and silicon melts at around 582-652°C far lower than pure Aluminium.

Knowledge of Aluminium Melting Point is Essential for its Application in Different Industries Because of the relatively low melting point compared to other metals, gallium is an easy and useful metal. The detectable results from Aluminium melting point reflect a great deal of its structure and nature within its low-melting temperatures that make suitable for working with in manufacturing, recycling, alloying or fabrication applications.

Thus recognizing the physical parameters impacting on aluminium’s relevant melting point and realizing its consequences, we can employ this fascinating metal to a greater extent. Through this, different industries also profited as well environmental sustainability. For any manufacturer, process engineer or materials scientist it is important to understand this and be able to take advantage of such a high temperature aluminium capability up the its melting point.
