Abstract

The present invention relates to a brazing flux for brazing metal, its composition includes (wt%) KAlF4+K3AlF6 cocrystal body 95.0-97.5, zinc fluoride 1.5-4.0, copper fluoride 0.2-0.5, tin fluoride 0.6-1.5 and cadmium fluoride 0.1-0.5. Said brazing flux is used for brazing stainless iron-aluminium.

Description

A kind of non-corrosive solder for soldering stainless iron and aluminium
Technical field
The present invention relates to a kind of solder bonding metal brazing flux, particularly a kind of different metal solder without corrosive brazing flux.
Background technology
Gong Ying stainless steel-aluminium soldering in the market all is ptfe aluminum potassium+potassium hexafluoroaluminate (KAlF with brazing flux 4+K 3AlF 6) eutectic, it is successful being used for stainless steel-aluminium composite brazing, the soldering qualification rate is greater than 99.9%.But this brazing flux is unsuitable for the welding of stainless iron-aluminium.To use potassium fluoroaluminate eutectic brazing flux, silicon-aluminium eutectic solder to be example, the hot strength of the stainless iron-aluminium of its welding is lower.The soldering qualification rate is very low, has only about 60%, can not be used for the suitability for industrialized production of the sector.
Summary of the invention
The purpose of this invention is to provide a kind of non-corrosive solder for soldering stainless iron and aluminium.
Stainless iron-aluminium soldering of the present invention in weight percent, comprises following component with brazing flux: ptfe aluminum potassium+potassium hexafluoroaluminate (KAlF 4+K 3AlF 6) eutectic 95.0～97.5, zinc fluoride 1.5～4.0, copper fluoride 0.2～0.5, tin fluoride 0.6～1.5.
Also comprise cadmium fluoride 0.1～0.5.
By mixing, ball milling to 200 purpose powder promptly can be made into stainless iron-aluminium soldering brazing flux of the present invention with above component.During welding, these add element and are cemented out and form alloy by aluminium, iron.This displacement, alloying process " liquefaction " surface of welding work pieces, improved the bond strength of solder and workpiece.
According to the GB11363-89 detection method, recording and drawing Shen intensity with the limit of potassium fluoroaluminate eutectic welding stainless iron-aluminium is 25N/mm 2Be up to 48N/mm with stainless iron of the present invention-aluminium pricker with the ultimate tensile strength that brazing flux without corrosion welds stainless iron-aluminium 2
Under the same process condition, use is with a kind of solder silicon-aluminium eutectic thing, use potassium fluoroaluminate eutectic brazing flux and non-corrosive solder for soldering stainless iron and aluminium weld diameter of the present invention to do contrast (the soldering sample number is 350) as stainless iron-aluminium-stainless steel tableware of 200mm, by weld strength and composite bed stability experiment, find that product percent of pass differs greatly.Use potassium fluoroaluminate eutectic brazing flux, product percent of pass is about 60%, uses stainless iron-aluminium soldering brazing flux of the present invention, and product percent of pass is greater than 99%.
Embodiment one
Percentage is got potassium fluoroaluminate eutectic 95.0%, zinc fluoride 3.00%, copper fluoride 0.5%, tin fluoride 1.5% by weight, mixes the back and is milled to 200 orders at the ball mill endosphere.Recording the limit, to draw Shen intensity be 29N/mm 2
Embodiment two
With embodiment one.Get potassium fluoroaluminate eutectic 95.0%, zinc fluoride 4.0%, copper fluoride 0.2%, tin fluoride 0.8%.Recording ultimate tensile strength is 32N/mm 2
Embodiment three
With embodiment one.Get potassium fluoroaluminate eutectic 97.5%, zinc fluoride 1.2%, copper fluoride 0.4%, tin fluoride 0.6%, cadmium fluoride 0.3%.Recording the limit, to draw Shen intensity be 48N/mm 2
