Where can I purchase Mu-metal rods?

BROMETHIOUS

Does anyone know of a source for Mu-metal/Nickel-iron rods without having to have custom made? I'm looking for 2 - 1" diameter by 3 to 4 inches length for an electromagnetic experiment. This is my first time dealing with this alloy, is it expensive? How much would I be looking at to have custom machined/cast? Thanks, Joshua

Hi,
There should be lot of industries selling alloys. For research see this website (click 'Alloys and go to MUmetal section'). Prices are also given in that website. I have no experience in buying with these people but should be little bit expensive i guess (it is popular at least in some universities). You can contact them for a specific alloy composition of your choice.
