Is the quality of the aluminium extrusion important when it comes to CNC tube bending?

Yes. Low-quality aluminium extrusion can sometimes undergo CNC tube bending without an issue, but it’s important to remember that cheaper extruded aluminium is less likely to perform well under machining. Using cheap, low-quality aluminium extrusion is more likely to result in poor quality bends, increased amounts of scrap and wastage, and even breakage during the bending process. No matter how good the machinery and the process is, if the quality of the extrusion is too low, there’s not much we can do. When choosing the appropriate alloy for your application, it’s really important to bear in mind how it’s going to be worked, and how strong/malleable it is. Our technical team can advise you on the right kind of aluminium alloy for your project.
