The three-dimensional penetration method combined with semi-solid casting was used to fabricate superconducting wires from metal-powder composite superconducting materials of MgB2 with aluminum, magnesium, and zinc alloys, having lightweight and good formability properties.Measured electrical resistivity showed a clear signal of superconducting transition between 25 and 39 Kfor all the samples cut out from the composites. A magnetic hysteresis loop indicated that simultaneously doped Al and Zn to magnesium host-matrix （MgB2/Mg-Al-Zn) enhanced the critical current density. A superconducting wire of a diameter of 1.0 mm was successfully extruded from the composited billet of MgB2/Al.

采用三维熔透法结合半固态铸造技术制备了重量轻、成形性能好的MgB 2/Al、Mg、Zn复合超导材料，测量了其电阻率，发现在25 ~ 39 K之间有明显的超导转变信号。磁滞回线表明，同时掺杂Al和Zn到镁基质（MgB 2/Mg-Al-Zn）提高了临界电流密度。用MgB_2/Al复合坯料成功地挤压出直径为1.0mm的超导线材。
