"Exist any iron meteorite without nickel?" none --(so far!)--- and very
unlikely. The two elements are so similar; atomic weight, metallic bond, and by
physical size of their atoms that there is little way to physically separate
them without a heavy planet's gravitational centrifuge. Chemically, here on
Earth with free oxygen, iron reacts much more readily than nickel and can
precipitated by that means.
