<p>PURPOSE:To manufacture the title metallic material suppressing grain growth which forms a flute having good tone quality by regulating Ag to the essential components and adding specific ratios of Cu, Mn, Ti, Zr and Si thereto. CONSTITUTION:Ag is regulated to essential components and to which, by weight, 5 to 28% Cu and 0.05 to 1% of one or more kinds among Mn, Ti, Zr and Si are added to prepare a metallic material for a flute. By manufacturing a flute in the use of said metallic material, its softening and the coarsening of grain are suppressed, by which the flute having excellent tone quality particularly in the range from medium frequency to high frequency can be obtd.</p> |
