Understanding the Technology Behind Aluminum Corner Extrusions

Aluminum corner extrusions are widely used in various industries due to their exceptional properties, versatility, and durability. This article delves into the technology behind these versatile components, providing a comprehensive understanding of their manufacturing process, benefits, and applications.

Extrusion Process

Aluminum corner extrusions are produced through a process called extrusion. In this process, molten aluminum alloy is forced through a precisely shaped die, resulting in a continuous profile with the desired geometric shape. The shape of the die determines the form of the extrusion, including its length, cross-sectional shape, and wall thickness. The extruded material is then cooled and cut to specific lengths.

Alloy Composition

The choice of aluminum alloy for corner extrusions depends on the specific requirements of the application. Commonly used alloys include 6063, 6061, and 6463, which offer a balance of strength, corrosion resistance, and workability. These alloys can be further strengthened through heat treatment processes to enhance their mechanical properties.
