Problems solved by technology

However, its performance can only replace 45B silver solder, and cannot replace BAg50CuZnSnNi, BAg50CuZnCd and other silver solders. The performance still cannot meet the requirements, and the amount of silver is still too much, and the cost is high.

Abstract

The invention relates to a multielement rare-earth silver solder which contains elements, such as manganese, indium, tin and the like. The multielement rare-earth silver solder is suitable for soldering metallic materials, such as red copper, brass, carbon steel, hard alloy, stainless steel and the like. The multielement rare-earth silver solder consists of the following components in percentage by weight: 23-29 wt% of Ag, 32-42 wt% of Cu, 0.5-2 wt% of Sn, 0.5-2.0 wt% of In, 0.5-2.2 wt% of Mn, 0.01-0.1 wt% of mischmetal, 0.01-0.1 wt% of Si, 0.01-0.1 wt% of Ni, 0.01-0.1 wt% of Li, 0.01-0.1 wt% of Ga and the balance of Zn. The multielement rare-earth silver solder has the advantages of high cost performance, capability of replacing BAg50CuZnSnNi and BAg50CuZnCd, exclusion of cadmium (Cd), lower melting temperature and good soldering property.

Description

technical field [0001] The invention relates to a multi-element rare earth silver solder containing manganese, indium, tin and other elements, which is especially suitable for brazing of metal materials such as red copper, brass, carbon steel, hard alloy and stainless steel, and can be widely used in refrigeration It is a kind of medium temperature brazing material in the brazing of industries such as machinery, electromechanical and so on. Background technique [0002] For the brazing between different metal materials such as copper and iron alloys, considering the wettability of the solder to the brazing base metal and the mechanical properties of the brazed joint, most people choose high-silver solder with a silver content greater than 40%. . The common BAg50CuZnSnNi and BAg50CuZnCd can be used for brazing copper and copper alloys, stainless steel, carbon steel, and hard alloys. However, as the price of non-ferrous metal raw materials continues to rise, especially the p...
