Continuous metal strips are formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. Critical selection of nozzle dimensions, velocity of movement of the chill body surface, and gap between nozzle and chill body surface permits production of continuous polycrystalline metal strip at high speeds, and of amorphous metal strips having high isotropic strengths, heretofore unobtainable dimensions, and other isotropic physical properties such as magnetizability.

A method of forming continuous strip of amorphous metal from a molten alloy capable of forming an amorphous structure comprising: a. forcing the molten alloy under pressure through a slotted nozzle positioned generally perpendicular to the direction of movement of a chill surface and located in close proximity to the chill surface to provide a gap of from about 0.03 to about 1 millimeter between said nozzle and the chill surface; b. advancing the chill surface, at a predetermined speed; and c. quenching the molten metal in contact with the chill surface at a rapid rate to effect solidification into a continuous amorphous metal strip.
