Metal Plates
3 months ago, Mrs K broke her ankle and had to have a bit of Meccano screwed to the bone. (Tenuous aviation link - she still can't put much weight on it so climbing up into the group Robin is not possible at the moment.) Last night I was massaging it and realised that I could feel the outline of the plate, one comment lead to another and eventually we wondered if I could hang a magnet on her leg and use it as a noticeboard.
At this point, we both realaised that we hadn't a clue what the plate is made from. So to satisfy our curiousity, can someone enlighten us as to the material. We discarded mild steel as too rusty, aluminium as too ductile, titantium as too expensive and more or less plumped for stainless.
