Abstract

The invention discloses a high-performance green brazing material which comprises a main material and an auxiliary material. The auxiliary material is 25-30 parts of a Sn-Ag-Cu lead-free material. The auxiliary material is prepared from 6-10 parts Zn, 4-6 parts of In, 6-8 parts of B, 2-4 parts of P, 3-9 parts of Ni, 5-7 parts of Mn and 7-9 parts of Co. The high-performance green brazing material completely avoids heavy metal carcinogenic elements of lead and cadmium, the brazing material is environment-friendly, and human bodies are prevented from being severely hurt; the brazing material is rich in ingredient, and the brazing performance is improved; the Zn, the In and the P are added in the formula, and therefore the effect of increasing the mobility of the brazing material in a molten state is achieved, and the brazing efficiency is high; the Co and the Ni are added in the formula, and therefore the effect of reinforcing the high strength and toughness of the brazing material is achieved; and the Mn is added in the formula, and therefore the effect of reducing the melting temperature space is achieved.

Description

technical field [0001] The invention relates to the technical field of brazing materials, in particular to a high-performance green brazing material. Background technique [0002] Brazing is to use a metal material with a lower melting point than the base metal as the solder, heat the weldment and the solder to a temperature higher than the melting point of the solder and lower than the melting temperature of the base metal, use liquid solder to wet the base metal, fill the gap between the joints and The method of interdiffusion with the base metal to realize the connection of the weldment. The brazing deformation is small, and the joint is smooth and beautiful. It is suitable for welding precision, complex and components composed of different materials, such as honeycomb structure plates, turbine blades, hard alloy tools and printed circuit boards. Before brazing, the workpiece must be carefully processed and strictly cleaned to remove oil stains and excessively thick oxid...
