A measure of metal’s capacity to flow; the plasticity of a material as force is applied to it. In the context of tube-bending, ductility is the ability of the tubing material to compress or elongate at the point of bend. The greater a tube capacity to flow at the point of bend, the greater its ductility; in this sense, ductility is roughly the opposite of rigidity.

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
