Aluminum is one of the most widely used non-ferrous metals across industries ranging from aerospace and automotive to packaging and construction. Its thermal characteristics—especially its melting temperature—are critical in processes like casting, welding, and extrusion. Understanding what temp aluminum melts at is essential for engineers, manufacturers, and procurement professionals dealing with high-temperature applications or material selection.
Pure aluminum melts at a precise temperature of 660.3°C (1220.5°F). This relatively low melting point makes aluminum ideal for manufacturing processes that require energy efficiency and precise thermal control, such as die casting, rolling, and thermal forming.
While pure aluminum has a well-defined melting point, most industrial applications use aluminum alloys, which contain varying percentages of elements like copper, magnesium, silicon, zinc, or manganese. These additives change the melting behavior of aluminum, often resulting in a melting range rather than a single temperature.
| Alloy Series | Common Elements | Melting Range (°C) | Melting Range (°F) |
|---|---|---|---|
| 1xxx (Pure Aluminum) | 99%+ Aluminum | 645–658°C | 1193–1216°F |
| 2xxx | Copper | 510–638°C | 950–1180°F |
| 5xxx | Magnesium | 570–640°C | 1058–1184°F |
| 6xxx | Magnesium & Silicon | 555–650°C | 1031–1202°F |
| 7xxx | Zinc | 475–635°C | 887–1175°F |
The melting temperature of aluminum affects not just how it's processed but also where it can be applied. Key industrial considerations include:
Welding and Brazing: Avoiding deformation or overheating during joining processes.
Casting and Extrusion: Ensuring proper fluidity and mold fill characteristics.
Thermal Management: Applications in electronics and heat exchangers benefit from predictable thermal behavior.
Structural Integrity: High-heat environments require careful alloy selection to prevent softening or failure.
| Grade | Alloy Series | Melting Range (°C) | Applications |
|---|---|---|---|
| 6061 | 6xxx | 582–652°C | Structural components, piping, marine parts |
| 7075 | 7xxx | 475–635°C | Aerospace, sports equipment, tooling |
| 2024 | 2xxx | 500–638°C | Aircraft structures, transportation |
Compared to other common engineering metals, aluminum has a relatively low melting point, which offers advantages in processing but may limit its use in extreme-temperature environments.
| Metal | Melting Point (°C) | Melting Point (°F) |
|---|---|---|
| Aluminum | 660°C | 1220°F |
| Steel (Carbon) | 1425–1540°C | 2600–2800°F |
| Copper | 1085°C | 1985°F |
| Zinc | 419.5°C | 787°F |
Pure aluminum melts at 660.3°C (1220.5°F). Alloys may melt at lower or higher temperatures depending on their composition.
No. Aluminum alloys melt over a range of temperatures, typically between 475°C and 660°C, depending on the alloying elements.
It determines how the material can be cast, welded, extruded, or used in high-temperature environments. The lower melting point also affects thermal management applications.
While aluminum has excellent heat conductivity, it may soften or lose strength at elevated temperatures. Choosing the right alloy is essential for thermal performance and safety.
