Aluminium Extruded Tubes are metal tubes manufactured from aluminum and produced by method of extrusion.
Extrusion is a manufacturing process that is designed to produce objects (like tubing) of a fixed cross-sectional profile. The Aluminum is drawn or pushed through a die, the die is manufactured in the shape of the desired cross section. These can be created using a manufacturing process however extrusion has two main advantages:
Very complex cross section can be manufactured via extrusion.
Because the material used in this process only encounters shear and compressive stress, brittle materials can be worked with.
Hot or Cold material can be used in this process and manufacture can be continuous or semi-continuous. Semi-continuous produces many pieces whilst continuous produces in theory an indefinitely long piece.
Aluminium is not the only material that can be used to make these tubes; below I have listed some other materials and their manufacturing properties:
Aluminium: this is the most common material and can be extruded hot or cold, if extruded hot it is heated to between 300 - 600 degrees Celsius.
Titanium: is heated between 600 - 1000 degrees Celsius and is mainly used to manufacture aircraft components.
Copper: heated the same as titanium is used also to create tubing, pipes, rods etc. A large pressure often more than 100ksi is required to extrude copper.
Lead and Tin: heated at a lower temperature than copper but used to manufacture the same products.
Magnesium: this is another material used to manufacture aircraft parts and is as easy to extrude as aluminium.
