Abstract (en)
[origin: JPS6437597A] PURPOSE: To obtain a new echo dimensions by specifying a tin content of cymbals made of bronze which mainly contains copper and a relatively small amount of tin. CONSTITUTION: The tin content of cymbals is set to 13 to 18wt.%, preferably, 14 to 16wt.%, and at most 1wt.% phosphorus is contained. In the forming process, a disk which is not provided with a dish-shaped projection or is already provided with it is especially subjected to cold forging and is treated so as to have about 3 to 15μm particle size. Thus, a large sound volume is obtained, and the reverberation spreads and is soft and penetrates well and is massive, and a new echo dimension is obtained.
