Abstract
The present invention aims at providing bronze alloy for a musical instrument that has high strength and processability and is provided with excellent acoustic characteristics by addition of Zr. The bronze alloy for a musical instrument according to the present invention has a component composition that contains 18% by mass to 26% by mass of Sn, 0.0005% by mass to 0.25% by mass of Zr, and a remainder consisting of Cu and inevitable impurities. Bronze alloy for a musical instrument having high strength and processability is obtained by setting the component composition as described above. Furthermore, from the frequency analysis result shown in FIG.A, in Example 13, higher harmonic components increase and low frequency waves also increase as compared with Comparative Example 2, and it is known that the enhancement of sound qualities such as complexity of beat sounds, profound feeling, and audibility is obtained.
