The melting point is the temperature at which a substance changes from a solid state to a liquid state, and may also be referred to as the melting temperature or melting point.
Melting point of aluminum alloy
In the field of chemistry and physics, melting point is a very important property because it can help us understand the properties and behavior of substances for proper selection and design in practical applications.
Melting points are usually expressed in degrees Celsius or Fahrenheit and can be determined or calculated experimentally.
Aluminum is a lightweight, strong, conductive, and corrosion-resistant metal that is used in a wide variety of fields. As a common metal material, the melting point of aluminum is an important property that people pay attention to. Here is a comparison of the melting points of aluminum and some other common metals:
Metals | Fahrenheit (f): | Celsius (c): |
Aluminum | 1,220 | 660 |
Yellow Brass | 1,660-1,710 | 905-932 |
Bronze | 1,675 | 913 |
Red Brass | 1,810-1,880 | 990-1,025 |
Copper | 1,983 | 1,084 |

Mercury (Hg) is the metal with the lowest melting point at normal temperature and pressure. Mercury is a silvery liquid metal that is solid below 20 degrees Celsius and liquid above 20 degrees Celsius, and has a melting point of -38.83 degrees Celsius (-37.89 degrees Fahrenheit), the lowest melting point of any known metal.
Aluminum ingot
In addition to mercury, there are other metals with relatively low melting points, such as sodium (Na), aluminum (Al) and magnesium (Mg), whose melting points are 97.72 degrees Celsius, 660.32 degrees Celsius and 650 degrees Celsius, respectively.
Aluminum alloy is an alloy material mixed with aluminum and other metals (such as copper, zinc, magnesium, etc.). Different grades of aluminum alloys have different melting points due to their different compositions. The following are melting point data for some common aluminum alloy grades:
Alloy | Melting Range (°F) | Melting Range (°C) | Applications |
1000 series | 1220 | 660 | Generally used in food packaging, electronic products, home building materials, auto parts, cooking utensils, etc. |
2000 series | 1018 – 1182 | 548-639 | Excellent characteristics such as high strength, rigidity, wear resistance, corrosion resistance and weldability,widely used in aviation, automobile, military industry, sports equipment and other fields. |
3000 series | 1058 – 1180 | 570-638 | 3000 series aluminum alloy has good corrosion resistance, weldability and formability, so it is widely used in food processing, construction, chemical industry, shipbuilding and other fields. |
4000 series | 1076 – 1184 | 580-640 | The 4000 series aluminum alloy has excellent characteristics such as high thermal expansion coefficient, low melting point, good machinability and corrosion resistance, so it is widely used in aviation, shipbuilding, electronics, metallurgy and other fields. |
5000 series | 1139 – 1211 | 615-655 | 5000 series aluminum alloys are widely used in aviation, automobiles, ships, construction and other fields |
6000 series | 1076 – 1211 | 580-655 | Building products, automotive parts, piping, furniture, bicycle frames, railroad cars,representative product-6061 aluminum |
7000 series | 716 – 1184 | 380-640 | Aircraft wings and fuselages, missile parts, gears and shafts, worm gears |
It should be noted that the above data are for reference only, and will be affected by many factors in actual application, such as material purity, heat treatment process, etc., which may cause a slight change in the melting point.
In addition, different aluminum alloy grades also have different mechanical properties, corrosion resistance, processing properties, etc., and it is necessary to select appropriate materials according to specific application requirements.
In general, the melting point of aluminum alloy is a very complicated issue, involving the influence of many factors. In practical applications, it is necessary to select a suitable aluminum alloy according to specific requirements and conditions to ensure that it has the required mechanical properties, corrosion resistance and heat treatment properties.
Aluminum Alloy | Melting Point (°C) | Melting Point (°F) |
1100 | 660 | 1220 |
2011 | 535 | 995 |
2024 | 505 | 940 |
3003 | 655 | 1215 |
5052 | 605 | 1120 |
6061 | 585 | 1085 |
6063 | 555 | 1030 |
7075 | 480 | 895 |
The answer is yes, first of all we need to understand the production process of aluminum alloy sheet/coil:
Aluminum sheet/coil
In the first step, the temperature must be raised to the melting point of aluminum (660 ° C), and the melting point of aluminum is increased, so the temperature of the ingot melting furnace needs to be increased;
The melting points of aluminum and aluminum alloys also have a certain impact on their applications. Aluminum alloys with lower melting points are doomed not to be used in application scenarios with higher ambient temperatures to ensure their own state;
7075 aluminum sheet is the strongest heat-treatable alloy, introduced by Alcoa in 1943, and can be heat-treated to achieve strength levels comparable to many steel alloys.
Heavy duty aluminum foil provides extra strength and tear resistance. Many cooks use it for baking, grilling, and storage. Most foil rolls marked "heavy duty" are between 0.0008" and 0.001" thick, which is roughly 0.02032-0.0254mm in national units
Aluminum circle for road sign refers to the aluminum circle used in the production of road signs. Because aluminum circles have strong corrosion resistance and weather resistance, aluminum circles are very suitable for the production of road signs.
Diamond aluminum sheet is a type of aluminum sheet that features a raised diamond pattern on one side, which provides excellent slip resistance and traction in wet and slippery conditions.
5052 aluminum sheet is part of the 5000 series of aluminum. The grades in this series are alloyed with magnesium (2.5%) and have medium to high strength properties.
6082 aluminium strip can usually be heat treated for higher strength, but relatively low ductility.6082 aluminum alloy is one of the alloy models of...
