  • Patent number: 12103113
    Abstract: 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.

  • Publication number: 20240068069
    Abstract: Copper-tin-nickel brazing material prepared by alloys recycled from E-waste, preparation method therefor, and system thereof are provided. A preparation method for the copper-tin-nickel brazing material includes the following steps: (a) spreading nano-SiO2 on the bottom of crucible and then adding a crude copper-tin-iron-nickel alloy recycled from E-waste; (b) heating the crucible to melt the crude alloy into a metal liquid so that Zn and Pb in the metal liquid react with the SiO2 to form a slag that floats out; (c) introducing a refining gas to the bottom of metal liquid in step (b), thereby removing the scums or gases formed by Pb, Fe, S, and O in the metal liquid; (d) performing heat-preserving directional solidification on the metal liquid, to bias-aggregate the Fe and Sb at one end and remove the same to obtain a copper-based intermediate alloy; and smelting and powdering the copper-based intermediate alloy.

  • Publication number: 20230405733
    Abstract: The present disclosure provides a copper-phosphorus brazing foil and a preparation method thereof, which relates to the technical field of brazing material. It comprises a copper inner core and a copper-phosphorus alloy layer coating outside the copper inner core, wherein the phosphorus content in the copper-phosphorus brazing foil is over 5 wt %, and the thickness of the copper-phosphorus brazing foil is below 0.5 mm. In the present disclosure, red copper foil is used as the core layer, and the surface of the red copper foil is alloyed with a layer of copper-phosphorus alloy by the eutectic reaction between the core layer and red phosphorus, such that the copper-phosphorus brazing foil is obtained. The present disclosure prepares a copper-phosphorus brazing foil with high phosphorus content and lower thickness. Comparing with the traditional preparation method, the preparation method of the present disclosure has high efficiency and high yield.

  • Publication number: 20230398645
    Abstract: A braze coating material with a nickel core and a coating, a preparation method thereof, and a braze coating method are provided. The braze coating material with a nickel core and a coating requires no binder and has strong adhesion ability, and includes the nickel core, a coating layer, a hardened layer, and a protective layer sequentially from inside to outside. The nickel core is metallic nickel having a surface subjected to a roughening treatment. The coating layer is a first brazing flux layer including hard particles, a first brazing flux, and a brazing filler metal powder. The hardened layer contains a second brazing flux and is covered with the protective layer mainly composed of a silicate.
