Al_<85>Ni_<10>Ce_5,Ti_<40>Zr_<10>Cu_<50> and Zr_<65>Al_<10>Cu_<15>Ni_<10> amorphous wires were produced by a newly designed method, i.e., melt extraction using a high frequency and an arc furnace. The wires have a circular cross section and a smooth peripheral surface, but small flaws are observed on the surface. The structure of the amorphous alloy wires is nearly the same as that of the melt-spun amorphous ribbons. The tensile strength and elongation are 930 MPa and 1.5%, respectively, for the Al_<85>Ni_<10>Ce_5 wire and 2000 MPa and 2.0%, respectively, for the Ti_<40>Zr_<10>Cu_<50> wire. The Zr_<65>Al_<10>Cu_<15>Ni_<10> wire has a large supercooled liquid region of 95 K, the coefficient of thermal expansion of 9.2×(10)^<-6> K^<-1>, tensile fracture strength of 1590 MPa and fracture elongation of 2.2%.
