What Is Aluminum’s Melting Point?

Aluminum is one of the most commonly used metals across a wide range of industries, including aerospace, automotive, construction, and electronics. Its popularity is due to a combination of properties such as low density, high strength-to-weight ratio, corrosion resistance, and excellent thermal conductivity. One critical property that affects how aluminum is processed and used in manufacturing is its melting point.

In this article, we will explain what aluminum’s melting point is, how it compares to other metals, why it matters in industrial applications, and how it influences fabrication techniques. As a global supplier of premium aluminum materials, sasaaluminum provides valuable insights for engineers, designers, and buyers who rely on aluminum every day.

The Melting Point of Aluminum

The melting point of pure aluminum is approximately 660.3 degrees Celsius, which is equivalent to 1220.5 degrees Fahrenheit. This temperature is relatively low compared to other industrial metals such as steel, making aluminum easier and more energy-efficient to melt and shape.

This low melting point is one reason why aluminum is commonly used in processes such as extrusion, rolling, casting, and forging. It allows manufacturers to work with aluminum at lower energy costs and with greater flexibility.

Why Is Melting Point Important?

Understanding aluminum’s melting point is essential for several reasons:

1. Manufacturing Processes

Processes like welding, casting, and extrusion rely on the ability to heat and shape aluminum. Knowing the exact melting point ensures that the metal is processed without damaging its structure.

2. Thermal Design

In industries like electronics and automotive, aluminum is often chosen for parts that experience heat. Engineers must be sure these parts operate well below the melting point to prevent deformation or failure.

3. Material Selection

When selecting materials for high-temperature environments, it’s important to know how aluminum will perform compared to other metals like copper or steel.

Does Alloying Affect the Melting Point?

Yes, the melting point of aluminum alloys can differ from that of pure aluminum. Depending on the alloying elements—such as silicon, magnesium, zinc, or copper—the melting range can be lower or higher than 660.3°C.

For example:

• 6061 aluminum alloy has a melting range of about 582°C to 652°C

• 7075 aluminum alloy melts between 477°C and 635°C

These variations are important when choosing materials for casting or heat treatment.

sasaaluminum offers a wide range of aluminum alloy products that meet specific performance and processing requirements.
