Recent improvements and developmental research on several high field superconducting wires are reviewed. High field characteristics of NbTiHf wires, wound in a 13.08 T superconducting magnet in a 1.8 K pressurized superfluid helium bath, have been studied in detail. Ti-alloyed Nb3Sn fm wires prepared by the Nb-tube method showed excellent high field Jc-characteristics and were wound in a 16.7 T superconducting magnet. One of these wires was employed in the HOMER facility (a multipurpose superconducting magnet at KfK) and generated 20.15 T, recently. A new process called the clad chip extrusion (CCE) method has been developed for the preparation of superconducting Nb3Al wires. Short samples of the CCE processed Nb3Al wires showed Jc higher than 104 A/cm2 up to 18.8 T at 4.2 K. One of the in-situ processed V3Ga short sample wires prepared by an induction melting using a CaO crucible showed Jc=104 A/cm2 at 16.2 T and 4.2 K, which will be improved by further optimization of the process and the composition.
