What is the difference between drawn and extruded

First, a standard extruded aluminum tube is produced. Next, instead of allowing the newly extruded tube to cool, it is pushed through a second die to produce the tubing at the determined size.

This process is also known as cold drawing, and it is used primarily to decrease a larger diameter tube into a smaller one. This produces strong, high-quality tubing with exact dimensions, and a good surface finish. This makes this tubing even better for handling pressurized gases and liquids. We provide both extruded aluminum tubing and drawn seamless aluminum tubing in a wide variety of sizes and alloys.

Extruded Aluminum Extruded aluminum is created by heating aluminum stock and then forcing it through a die. Extruded Aluminum Tubing There are two types of aluminum tubing created by the extrusion process. Drawn Aluminum Where extruded aluminum is pushed through a die, drawn aluminum pulls molten aluminum into a mold.

Drawn Seamless Aluminum Tubing This is commonly called drawn structural tubing because the creation process for this produces stronger tubing. However, it all depends on the shape you are trying to produce. There you have it — answers to the most important questions regarding drawn and extruded aluminum.

A metal billet is shaped through smelting, solidifying, and rolling. The billet is heated up to a temperature suitable for extruding. The heat makes the metal more malleable and easier to form.

Pressure is exerted on the billet against the die. The dies used in extrusion have been precision machined to ensure that a quality piece of extruded metal with acceptable dimensions comes out the other side of the die.
