Abstract

See full text

The present disclosure relates to the field of brazing material technologies, and particularly to a copper-phosphorus brazing wire for brazing a copper alloy spectacle frame as well as a preparing method and system thereof. The copper-phosphorus brazing wire for brazing a copper alloy spectacle frame includes components with following mass percentage, 87.1%˜91.4% of Cu, 1.5%˜2.6% of Ag, 5.9%˜8.4% of P, 0.2%˜0.42% of Al and 0.8%˜1.68% of Si. For the copper-phosphorus brazing wire according to the present disclosure, through coordination and cooperation of the components, impurity content is low and joint strength is high in a welding process; a mass ratio of the Si to the Al is a constant value, and a dense oxide film may be formed on a surface of a molten pool to hinder volatilization of Zn in a base material.
