Hi,

I am looking for an acid to remove some indium leftovers from a copper
flange. The indium was used for a vacuum seal, but removing the last
pieces mechanically would damage the system. Does anybody know of a way to
chemically remove the indium selective over the copper ? If so what would
be a supplier of that solution ?

thanks
mike
