Embodiment 1
[0032] A kind of gong copper of the present invention, the mass percentage of Cu element in gong copper is 60.5~61%, the mass percentage of Sn element is 0.8~1%, the mass percentage of Mn element is 0.025~0.035%, the mass percentage of Pb element is The percentage is not more than 0.008%. When the content of each element meets the requirements of the above standards, the musical instrument reed made of gong copper can have a more beautiful sound quality, which is more in line with the market's quality requirements for gong copper. Specifically in the present embodiment, the mass percentage of Cu element is 60.5%, the mass percentage of Sn element is 0.8%, the mass percentage of Mn element is 0.025%, and the mass percentage of Pb element is 0.008%. It is composed of electrolytic copper, tin Ingots, manganese alloys and zinc ingots are processed after smelting, and the specific processing steps are as follows:
[0033] Step 1: smelting of raw materials;
[0034] The raw materia...
Embodiment 2
[0045] The present embodiment is the same as embodiment 1, and the difference is that the mass percentage of the Cu element in the gong copper of the present embodiment is 61%, the mass percentage of the Sn element is 1%, the mass percentage of the Mn element is 0.035%, and the Pb element The mass percentage is 0.003%, and the annealing temperature in the roller hearth furnace is 650°C.
Embodiment 3
[0047] The present embodiment is the same as embodiment 1, and the difference is that the mass percentage of the Cu element in the gong copper of the present embodiment is 60.8%, the mass percentage of the Sn element is 0.9%, the mass percentage of the Mn element is 0.03%, and the Pb element The mass percentage is 0.006%, and the annealing temperature in the roller hearth furnace is 640°C.
