MgB_2 has the highest critical temperature of superconducting transition (Tc) in the intermetallic compound superconductive material. We used the original method of the three-dimensional penetration casting (3DPC) in this laboratory to manufacture the MgB_2/Al composite which assumed pure Al as a matrix. In the composite material we made, MgB_2 particles disperse to the Al matrix uniformly. The Tc was determined by electrical resistivity and magnetization to be about 37 〜 39K. In this work, we report a rise of the critical current density (Jc) by changing the matrix from pure Al to Al alloy, Pure Mg, or Mg alloy.
