The invention discloses a preparation method of an all-metal iron-based amorphous strip and an amorphous wire. The preparation method comprises the following steps: preparing a mother alloy ingot; preparing the amorphous strip: putting the mother alloy ingot into a quartz tube with a hole at the bottom and adjusting inner and outer pressure intensity difference of the quartz tube, heating to meltthe mother alloy ingot into a molten state, spraying the molten-state mother alloy out of the hole at the bottom of the quartz tube by utilizing the inner and outer pressure intensity difference of the quartz tube, beating on a rotating copper roller, and throwing out by the rotating copper roller to obtain the amorphous strip; and preparing the amorphous wire: putting the mother alloy into a crucible, enabling the center of the crucible to be dead against the edge of a molybdenum roller, heating the crucible to melt the mother alloy into a ball shape, heating the crucible to enable the molten-state mother alloy to co
