subject: Extruded Aluminium And Its Process [print this page] A process that works on totally different forms of metals to change their shapes and forms is called extrusion. Extruded aluminium is the most common product of this method. You'll be able to make many things from extruded aluminium by punching numerous hollow cavities through it or putting a number of slots so that you could place bars or any material to connect it to one or more of it.
Aside from aluminium, you can find several more materials which you can extrude. But before I enumerate some more of them, let me explain further what extrusion is and how it is done.
In order for you to change the shape of a metal, you should apply heat to it so that it will melt. You can also make use of numerous instruments and machineries to help you with the entire process.
There are numerous types of extrusion - hot extrusion, cold extrusion as well as warm extrusion. In hot extrusion, the heat is kept at a high level to make sure that material is soft and won't harden quickly. Hydraulic presses can be used in this kind of process, that's the reason it's the most expensive among the 3 types.
In cold extrusion, the temperature is maintained at a degree that is equivalent or below the room temperature. This is done so that the finished products will have good surface finishes and better strength. Metal, copper, titanium, aluminum, lead, vanadium, molybdenum as well as tin are examples of materials commonly utilized in cold extrusion.
Finally, in warm extrusion, temperature is kept at a level greater than room temperature but lower than the material's recrystallization temperature. This is carried out to achieve the perfect ductility and extrusion properties.
Other generally used metals that may be extruded are these:
1. Copper - utilized in creating tubes, wire, cable sheathing and pipes
2. Metal - utilized in tracks and rods
3. Magnesium - used to manufacture nuclear industry parts and airplane components
4. Tungsten carbide - advisable to use due to its sturdiness and toughness
5. Zinc - used in handrails, tubes, bar, rods, fitting and several hardware parts
6. Lead - used in creating wire, pipes, cable sheathing and tubes
7. Tin - also used in the same manner as lead and copper
8. Titanium - used to manufacture engine rings, seat tracks for airplanes and different structural parts
You may use both extruded aluminium or extruded steel relying on your desired final product. Do not forget that each of these metals has a distinctive set of properties that will suit your needs.
