The Iron<unk>  is a stiff coronary<unk>  with poor steerability whose rigidness is used to straighten vessel segements and allow better transmission of forces pushing balloons or stents.  This property comes from the tendency of the wire to retain its shape rather than conform to the contours of the vessel.
