<p>Cryogenic high–speed rolling, where sheet specimen cooled in liquid nitrogen was supplied to a rolling mill with rolls rotating at 1500m/min at room temperature, was applied to Cu–5mass% Zn sheets. After 80% reduction of the cryogenic high–speed rolling by 2–pass operation, the rolled sheet showed tensile strength of 576MPa, total elongation of 5.3% and electrical conductivity of 54%IACS, while that by low–speed (5m/min) cold rolling showed 521MPa, 5.3% and 52%IACS, respectively. The improved balance of the cryogenic high–speed rolled sheet was attributed to fine–grained microstructure with deformation twins and brass–type rolling texture which were realized by the short contact duration of the cryogenic sheet with the rolls at room temperature.</p>
