Abstract

The invention discloses a method for processing a novel sound hole plate material. The raw materials comprise: 59 percent of high-purity cathode copper with copper content of not less than 99.9935 percent and lead content of not less than 0.0065 percent, 0.4 percent of tin ingot with tin content of not less than 99.995 percent and lead content of not less than 0.0035 percent, zinc ingot with zinc content of not less than 99.995 percent and no lead, and the balance of zinc. The method comprises the following operating steps of: melting copper, adding zinc and tin, mixing and casting; milling a face; performing hot rolling until the thickness is 3.2mm; performing cold rolling until the thickness is 0.32mm; and checking and warehousing. Due to the detection of a German SGS detection mechanism in Shanghai of China, the sound hole plate material has the actually measured lead content of 0.0089 percent and reaches the specified standard value, and the processed product fulfills the aim of fixing a sounding spring and realizing wonderful tone quality, environment friendliness and no toxin.
