Abstract
The present invention belongs to the field of non-ferrous alloy technology, and aims at developing one kind of low melting point silver-free copper-base brazing material with excellent wetting capacity to stainless steel and capacity of brazing stainless steel. The components (weight percent) are as follows: zn 30-40%, Mn 4-11%, Sn 1-4%, one or two of Re 0-1%, B0-0.50%, and Cu for the rest. The melting point of the invention is 777 ℃ of solidus line, 790 ℃ of liquidus line, 550MPa of tensile strength and delta of elongation5020 percent, the shear strength of a low-carbon steel brazing joint is more than 400MPa, and the shear strength of a stainless steel brazing joint is more than 200 MPa. It is suitable for salt bath and furnace brazing flame gas welding and high-frequency brazing.
Description
The invention belongs to non-ferrous alloy technology, is a kind of coper-base solder alloy prescription that does not contain precious metal.
Traditional copper base solder, routine H62, S221 etc., all unsuitable soldering stainless steel part.So far, the solder of argentiferous is all used in the soldering of stainless part.For this reason, all be the brazing filler metal alloy of base both at home and abroad with copper in development, the characteristics that are intended to reduce fusing point and keep silver solder again.
State Patent Office's result for retrieval on February 14 nineteen ninety (entrusting numbering 90009) shows; Up to now, the relevant patented technology that has has in the world all reduced the fusing point of copper base solder to some extent, but is to be used for soldering steel, copper and copper alloy mostly, does not solve stainless soldering problem as yet well.As: Russian Patent (27.12.77(21) 2568518/25-27), its brazing filler metal alloy composition and content are: Z

eA kind of, two kinds or three kinds of copper base solders, fusing point is 778-814 ℃.Be mainly used in the soldering of steel.
The objective of the invention is to develop a kind of copper base solder of new no silver, make it have good wettability stainless steel, but the soldering stainless steel.The soldering fusing point is reduced, realize energy-efficient.
Component of the present invention and content are: zinc (Z
n) 30-40%, manganese (M
n) 4-11%, tin (S
n) 1-4%, rare earth (R
e) in a kind of or two kinds of 0-1%, boron (B) 0-0.5%, surpluses be copper C
u
Its processing sequence is: smelting-ingot casting-Jia is hot extruded into silk or is rolled into paper tinsel.
Smelting is in proper order: during melting, add Cu, Mn earlier in melting kettle or other smelting equipments, to reduce fusing point, add S after the fusing
n,, add Z at last with further reduction fusing point
n, R
eAnd B.
Advantage of the present invention is that fusing point is low, is 777 ℃ of solidus, 790 ℃ of liquidus curves, and brazing temperature is 900-950 ℃, than low 200 ℃ of brass, remarkable energy saving effect (energy-conservation 30-40%) is arranged; Satisfactory mechanical property, tensile strength＞550MP
a, percentage elongation δ
50Be 20%, mild steel soldered fitting shearing strength＞400MP
a, stainless steel braze welding shearing strength＞200MP
a; Argentiferous, nickel, cobalt, bismuth, cadmium etc. are valuable and produce the element of pernicious gas when smelting in this solder, smelt simply, and processing characteristics is good; The solder good manufacturability, need not use special flux, stainless steel, steel, carbide alloy are had good sprawling and filling capacity, the butt joint gap is insensitive, can welding, stainless steel, steel, copper, copper alloy and carbide alloy, be suitable for salt bath and gas welding of furnace brazing flame and high frequency brazing.
