What is aluminum extrusion?

Aluminum extrusion is made of aluminum by heating aluminum blocks and pushing them through the shape of the mold to form a specific pattern. Extrusion can be made in many sizes and almost any shape of the mold can be created. Extruded aluminum provides durability and structural strength, and is completely recyclable.

Different aluminum alloys are processed at different temperatures. The temperature is measured when the aluminum extrudate leaves the die to determine the appropriate speed of the process. Aluminum extrudates are sometimes cooled with water or air when leaving the die. The extruded metal enters the cooling stage to further reduce its temperature.

Place the cooled extruded parts on the stretching equipment to straighten and harden them. The cooled and stretched aluminum extrusions can be cut to any desired length. Finally, the fragments are aged at room temperature or placed in an aging box, where they are heated to increase hardness and harden the metal.
