Additionally, the use of new alloys made it possible to produce extrusions with improved strength and corrosion resistance.

The 1960s and 1970s saw further developments in the use of aluminum extrusions, particularly in the automotive industry. As car manufacturers sought to reduce weight and improve fuel efficiency, aluminum extrusions became an increasingly popular choice for structural components such as body frames and engine parts. In recent years, there has been a growing interest in the use of aluminum extrusions in the renewable energy sector, particularly for solar panel frames and wind turbine components. This has driven further innovation in extrusion technology, with new methods and materials being developed to meet the unique demands of these applications.

Aluminum Extrusions

The Aluminum Extrusion Process

The process begins with the selection of high-quality billets and involves heating the billet to a specific temperature, then forcing it through a die under high pressure. There are two types of extrusion processes, hot and cold extrusion, each offering its own advantages and applications.

Hot extrusion involves heating the aluminum billet to a temperature of approximately 450°C (850°F) or higher before it is extruded. The heated billet is then forced through a die under high pressure. This process allows for the extrusion of large, complex profiles with precise shapes and dimensions. The high temperature during hot extrusion enhances the aluminum’s plasticity, making it easier to shape and form. Hot extrusion is often employed for manufacturing extrusions that require intricate designs, such as those used in the aerospace and automotive industries. The resulting extrusions have excellent mechanical properties and are well-suited for load-bearing applications.

On the other hand, cold extrusion involves extruding the aluminum billet at room temperature, without the need for preheating. The cold extrusion process offers several advantages, including improved surface finish and dimensional accuracy. It is particularly suitable for producing smaller, simpler profiles with consistent cross-sections. Cold extrusion is often used in applications where tight tolerances and surface quality are critical, such as in the production of electrical components, heat sinks, and precision parts. Additionally, cold extrusion requires less energy compared to hot extrusion, making it a more energy-efficient process.

Both hot extrusion and cold extrusion processes have their place in aluminum extrusion manufacturing, with each process tailored to specific requirements. The choice between the two depends on factors such as the size and complexity of the profile, the desired mechanical properties, dimensional precision, and surface finish. Manufacturers carefully consider these factors when determining which extrusion process to employ in order to achieve the desired outcome for their specific applications.

Various Types of Aluminum Extrusions

Aluminum extrusions come in a variety of types, each designed to fulfill specific functional and aesthetic requirements. Standard profiles are commonly available and widely used in various industries. These profiles typically have regular shapes, such as squares, rectangles, and rounds, and are readily accessible for a wide range of applications. Custom profiles, on the other hand, are specifically tailored to meet unique design requirements. They can be created with intricate and complex shapes, allowing for greater flexibility in product design.

Aluminum extrusions can also be categorized as hollow or solid profiles. Hollow profiles feature an open cross-section, providing a lightweight yet structurally efficient solution. They are often used in applications where weight reduction is critical, such as aerospace and automotive industries. Solid profiles, on the other hand, have a continuous, solid cross-section and are commonly used when enhanced strength and rigidity are required.

Structural and decorative profiles represent another distinction. Structural profiles are designed to withstand heavy loads and provide structural support. They are commonly used in applications such as building and construction, where strength and durability are essential. Decorative profiles, on the other hand, are primarily employed for aesthetic purposes, enhancing the visual appeal of products or architectural elements.

The wide range of types of aluminum extrusions allows manufacturers to select the most suitable profiles for their intended applications, considering factors such as functionality, structural requirements, aesthetics, and material properties. This versatility makes aluminum extrusions a highly adaptable solution in numerous industries, contributing to their widespread usage.

Aluminum Alloy Series’ Used for Extrusions

There are several series of aluminum alloys commonly used in various industries. The most commonly recognized series include the 1xxx, 2xxx, 3xxx, 4xxx, 5xxx, 6xxx, 7xxx, and 8xxx series. Each series represents a specific group of alloys with distinct properties and characteristics. The number before “xxx” denotes the major alloying element or elements present in the alloy. For example, the 1xxx series consists of almost pure aluminum, while the 2xxx series contains copper as the primary alloying element. Each series has its own unique set of properties, making them suitable for specific applications.

Among the various aluminum alloy series, the most commonly used for aluminum extrusions are the 6xxx series. These series are particularly well-suited for extrusion processes due to their excellent combination of strength, formability, and corrosion resistance. The 6xxx series alloys, such as 6061 and 6063, are widely utilized in aluminum extrusions. These alloys feature magnesium and silicon as their main alloying elements, providing good extrudability, weldability, and surface finish. They offer a balance of strength, formability, and corrosion resistance, making them suitable for a wide range of applications in industries like construction, automotive, and consumer goods.

The 5xxx series alloys, including 5052 and 5083, are also commonly employed in aluminum extrusions. These alloys are non-heat-treatable and primarily known for their excellent corrosion resistance. With magnesium as the primary alloying element, the 5xxx series alloys exhibit good formability and weldability. They are often utilized in marine and architectural applications where corrosion resistance is crucial.

While the 6xxx and 5xxx series are the most prevalent for aluminum extrusions, other series like the 7xxx series may also be used in specific applications where high strength is required, such as aerospace and high-performance industries. The choice of alloy series depends on the specific requirements of the application, including strength, corrosion resistance, and formability. Manufacturers carefully select the appropriate alloy series to ensure the desired performance and functionality of the extruded aluminum products.
