The invention relates to a novel gold alloy material and a method for manufacturing the same, and belongs to the field of precious metal braze welding materials. The method for manufacturing gold alloy by the aid of a high-energy ball-milling technology includes preparing raw materials such as gold powder, gallium powder, germanium powder, antimony powder, tellurium powder and tin powder according to requirements of chemical compositions and a formula of the alloy, and performing mechanical high-energy ball-milling on the raw materials under a vacuum condition for 5-20 hours to manufacture gold alloy brazing filler metal powder; stirring and mixing the gold alloy brazing filler metal powder, solvents, auxiliaries, binders and the like for 1-3 hours to manufacture brazing filler metal welding paste. The particle sizes of the gold powder, the gallium powder, the germanium powder, the antimony powder, the tellurium powder and the tin powder are smaller than 200 meshes (the average particle sizes are smaller than 70 micrometers), and the purity of the gold powder, the gallium powder, the germanium powder, the antimony powder, the tellurium powder and the tin powder is higher than 99.995%. The novel gold alloy material and the method have the advantages that the alloy brazing filler metal powder manufactured by the aid of the method is excellent in product performance and low in manufacturing cost, processes for manufacturing the alloy brazing filler metal powder are controllable, the manufactured brazing filler metal welding paste is excellent in comprehensive performance, service requirements of relevant industries of integrated circuits, electronics, computers, electric appliances and the like can be met, and the like.
