| A process that works on different kinds of | | | | materials commonly used in cold extrusion. |
| metals to change their shapes and forms is called | | | | Finally, in warm extrusion, temperature is kept at |
| extrusion. Extruded aluminum is the most | | | | a level greater than room temperature but lower |
| common product of this method. You can create | | | | than the material's recrystallization temperature. |
| many things from extruded aluminum by punching | | | | This is done to achieve the best ductility and |
| a number of hollow cavities through it or putting | | | | extrusion properties. |
| several slots so that you can place bars or any | | | | The other commonly used metals that can be |
| material to connect it to one or more of it. | | | | extruded are the following: |
| Aside from aluminum, there are several more | | | | 1. Copper - used in making tubes, wire, cable |
| materials which you can extrude. But before I | | | | sheathing and pipes |
| enumerate some more of them, let me explain | | | | 2. Steel - used in tracks and rods |
| further what extrusion is and how it is done. | | | | 3. Magnesium - used to manufacture nuclear |
| In order for you to change the shape of a metal, | | | | industry parts and aircraft parts |
| you should apply heat to it so that it would melt. | | | | 4. Tungsten carbide - advisable to use because of |
| You can make use of several tools and | | | | its durability and toughness |
| machineries to help you with the whole process. | | | | 5. Zinc - used in handrails, tubes, bar, rods, fitting |
| There are various types of extrusion - hot | | | | and many hardware components |
| extrusion, cold extrusion and warm extrusion. In | | | | 6. Lead - used in making wire, pipes, cable |
| hot extrusion, the temperature is kept at a high | | | | sheathing and tubes |
| level to ensure that material is soft and will not | | | | 7. Tin - also used in the same way as lead and |
| harden easily. Hydraulic presses are often used in | | | | copper |
| this type of process, that is why it is the most | | | | 8. Titanium - used to manufacture engine rings, |
| expensive among the three types. | | | | seat tracks for airplanes and other structural |
| In cold extrusion, the temperature is maintained | | | | components |
| at a level that is equal or below the room | | | | You can use either extruded aluminum or |
| temperature. This is done so that the finished | | | | extruded steel depending on your desired final |
| products will have good surface finishes and higher | | | | product. Remember that each of these metals |
| strength. Steel, copper, titanium, aluminum, lead, | | | | has a unique set of properties that would suit |
| vanadium, molybdenum and tin are examples of | | | | your needs. |
