Abstract;Two types of (Nb,Ti)3Sn conductors, which were developed to realize a high critical current density in a high magnetic field and 0.2% proof strength, have been manufactured for the production of 920MHz-NMR magnets. The conductors show superconducting properties depending on heat treatment temperature and duration which are required for heat-treating (Nb,Ti)3Sn coils homogeneously. Fluctuations of the critical current density of the manufactured conductors are so small that ratios of standard deviations to averaged critical current density are less than 3%. The all manufactured conductors meet the demands for the respective designed targets. (author abst.)
