Extruded aluminum is forced from a die at a temperature near melting, like out of a giant, hot grease gun.
Aluminum tube is extruded.
If you look at an extrusion in cross section, the thickness often varies, and has clean, square corners. A good analogy is printed lettering. The fancier typefaces have thickness variation. Also, extruded usually has odd shapes, like letters. You could form a letter "t" or "k" cross section with extruded.
Heatsinks found inside computers and monitors are extruded, for example.
Rolled stuff is always the same thickness throughout, since it is formed from a sheet. |
