1. Those benders are for soft copper pipe.
2. The mostly commonly used type of copper pipe used in domestic plumbing is "half hard".
3. Those benders can't handle half hard copper.
4. If you heat the copper to bright red, then quench or allow to cool in air, it will become soft and you might be able to bend it.
Thanks for that, I think I will give it a go!1. Annealing makes a metal more ductile and easier to work. Like a number of other metals, copper work hardens when it is hammered / squeezed through an extrusion die.
2. There isn't much practical difference between the strength of soft and half hard copper, and either is quite suitable for domestic plumbing.
3. There is much wider use of annealed copper in air conditioning / refrigeration work, which tend to use narrower pipes. These lend themselves to bending more easily and can be used to form much tighter (small radius) curves.
Give what a go? Whatever you do to a 15mm pipe you aren't going to successfully bend it with a tool which is designed for 8mm & 10mm pipe. If you can get the 15mm pipe soft enough to bend with that tool it will just get crushed.Thanks for that, I think I will give it a go!
