Problems solved by technology

[0002] The content of alloy Si and Mg elements in the existing aluminum-based brazing materials is too broad. When the Si content is too high, the fluidity of the metal is strong, which is easy to cause the welding material to sag and overflow, and affect the product quality; and when the Mg content is low When it is used, it is easy to form virtual welding and affect product quality; therefore, it is urgent to provide an aluminum-based brazing material with a suitable ratio and a suitable manufacturing process to achieve a balance, which will neither cause sagging and overflow of the welding material, nor It will cause false welding and affect the quality of the product

Embodiment Construction

[0028] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0029] like figure 1 As shown, an aluminum-based brazing material, which contains 9.0-9.5% Si by mass percentage, 0.6% Fe, 0.2% Cu, 0.1% Mn, 1.6-1.9% Mg, 0.2% Zn, The total content of other impurities does not exceed 0.15%, and the content of a single type of impurity does not exceed 0.05%, and the balance is Al.

[0030] Specifically, it contains Si with a mass percentage of 9.2-9.3%.

[0031] Specifically, it contains Mg with a mass percentage of 1.7-1.8%.

[0032] Specifically, it contains other impurities with a mass percentage not exceeding 0.1%.

[0033] Specifically, a manufacturing process of the material includes the following steps:

[0034] (1)...

Abstract

The invention relates to an aluminum-based brazing material. The aluminum-based brazing material is characterized by comprising, by mass, 9.0-9.5% of Si, 0.6% of Fe, 0.2% of Cu, 0.1% of Mn, 1.6-1.9% of Mg, 0.2% of Zn, no greater than 0.15% of other impurities in total, and the balance Al, specifically, the amount of each single impurity of the other impurities is no greater than 0.05%. The sagging, spillover and pseudo soldering of the brazing material are effectively controlled; the qualified rate is increased; and the cost is reduced.

Description

technical field [0001] The invention relates to an aluminum-based material, in particular to an aluminum-based brazing material and a manufacturing process thereof. Background technique [0002] The content of alloy Si and Mg elements in the existing aluminum-based brazing materials is too broad. When the Si content is too high, the fluidity of the metal is strong, which is easy to cause the welding material to sag and overflow, and affect the product quality; and when the Mg content is low When it is used, it is easy to form virtual welding and affect product quality; therefore, it is urgent to provide an aluminum-based brazing material with a suitable ratio and a suitable manufacturing process to achieve a balance, which will neither cause sagging and overflow of the welding material, nor It will cause false welding and affect the quality of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overco...
