Different alloys and their tempers are applicable for custom extrusions, and their performance characteristics can differ. The extrusion manufacturing process, coupled with the right quenching of the material, results in different alloy options. Each of these alloys has its performance levels. You want to choose the extrusions depending on the performance characteristics of the alloy or its tempers. For instance, if you are looking for a corrosion-resistant custom aluminum extrusion, 5052 and 5083 aluminum are good options. There are many other aluminum alloys to consider depending on the performance characteristics – 7075 alloy custom aluminum extrusion, 6061 alloy custom aluminum extrusion, and so on. The options are even wider with tempers.
