C2700 (65:35 brass)
Alloy number | Characteristic | Use |
C2700 (65:35 brass) | C2700 has expansibility, and cold-work characteristics are good, and it is high, and I bend it, and the strength is used for a complicated artefact, a deep drawing artefact widely by processing as the nature, the diaphragm nature are good. For a characteristic, a use, As conductivity is good, I am used for an electric appliance material and am used for the heat exchanger of the chemical factory, a steam pot, the heat exchanger material of the air conditioner as a specific thermal conductivity is high. In addition, because there is the characteristic full of expansibility, I can facilitate reducing work and bending and am used for daily necessities, the household articles such as an electric clasp, a case, a writer, the hook of cosmetics. Besides, as there is not low temperature brittleness, even very-low temperature is used, and luster is used in construction materials and various kinds of instruments by beautiful gold. | Electric appliance material, household articles, communication machine, precision instrument parts |
