Aluminum Extrusions

Aluminum Extrusions Manufacturers List

The process of aluminum extrusion was further refined by companies such as Alcoa and Kaiser Aluminum during the 1940s and 1950s. During this time, extrusion technology became more advanced, allowing for the production of more intricate and complex shapes. 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.

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.

Hot extrusion involves heating the aluminum billet to a temperature of approximately 842°F (450°C) and extruding it while hot. This method is typically used for large, complex profiles that require a high degree of precision. Cold extrusion, on the other hand, involves extruding the aluminum billet at room temperature, which is ideal for smaller profiles with simple shapes.

Various Types of Aluminum Extrusions

Aluminum extrusions come in various types, including standard and custom profiles, hollow and solid profiles, structural and decorative profiles, and different alloys used in extrusions. Standard profiles are commonly used in construction and manufacturing, while custom profiles are made to specific design requirements.

Hollow and solid profiles are designed with either an open or closed cross-section. Structural profiles are used to support heavy loads, while decorative profiles are used for aesthetic purposes. Different alloys used in extrusions have different properties, making them suitable for specific applications.

Limitations of Aluminum Extrusions

One of the limitations of aluminum extrusions is the size and complexity of the extruded profiles. The extrusion process can only produce profiles of certain sizes and shapes, making it difficult to produce intricate designs. Additionally, there is a risk of surface damage during the extrusion process, and distortion or warping during cooling.

Benefits of Aluminum Extrusions

Aluminum extrusions offer many benefits, including a high strength-to-weight ratio, corrosion resistance, versatility in design, energy efficiency, and recyclability. Aluminum extrusions are also lightweight, making them easier to handle and transport, reducing manufacturing and transportation costs.
