Abstract
Disclosed a non-cadmium silver solder containing gallium and cerium belongs to the weld material. The non-cadmium silver solder comprises following chemical components at mass percent: copper (Cu) at 17.0-21.0%; zinc (Zn) at 16.0-20.0%; stannum (Sn) at 3.0-6.0%; cerium (Ce) at 0.001-0.10% and other is argentine (Ag). The solid phase liner temperature ranges from 605-615Deg. C while the liquid phase liner temperature ranges from 635-645Deg. C. The invention utilizes common intermediate frequency smelting-furnace to smelt, casting, compress and stretch to attain demanded solder filamentary material. Said solder do not have any harmful element cadmium (Cd) to avoid the environmetal pollution. And the invention can replace the solder as BAg50CuZnCd and BAg50CuZnCdNi which contain cadmium to match the soldering flux of FB102 (QJ102), while it is used to match red-copper-brass, brass-carbon steel, stainless steel-nickel base alloy; it has same wetting property and extension property on the base metal while its mechanics property can reach sigmab=180-350MPa and tau=160-300MPa.
Description
One, technical field
The present invention relates to a kind of cadmium-free silver brazing alloy that contains gallium and cerium, particularly relate to a kind of cadmium-free silver brazing alloy that has solders such as good brazing property, suitable solid-liquid phase line, alternative BAg50CuZnCd, BAg50CuZnCdNi, BAg45CuZn, is applicable to metal material solderings such as red copper, brass, carbon steel, stainless steel and nickel-base alloy, this kind cadmium-free silver brazing alloy has and traditional suitable combination property of cadmium brazing silver alloy (BAg50CuZnCd, BAg50CuZnCdNi) that contains, and belongs to the brazing material of class of metal materials and field of metallurgy.
Two, background technology
Present silver solder BAg50CuZnCd, the BAg50CuZnCdNi that uses contains the cadmium (Cd) of 17.0%-19.0%, 15.0%-17.0% respectively in its chemical composition.Because the promulgation of European Union " WEEE " and " ROHS " two instructions, and in enforcement on July 1 in 2006, the material that contains cadmium will not allow to use in many household electrical appliances are produced, and must research and develop out the substitute products that do not contain cadmium.This invention " a kind of cadmium-free silver brazing alloy that contains gallium and cerium " is promptly finished under this technical background.
Three, summary of the invention
The task of this invention provides a kind of silver solders poisonous element cadmium, good, the alternative BAg50CuZnCd of brazing property, solders such as BAg50CuZnCdNi, BAg45CuZn that can the welding position in brazing process and after the soldering do not have fully.
This invention has mainly solved following two key technical problems: 1) develop silver solder no cadmium, alternative BAg50CuZnCd, BAg50CuZnCdNi, by optimizing the chemical composition of " cadmium-free silver brazing alloy that contains gallium and cerium ", obtained mother metal wetability, good, the brazed seam mechanical property (σ of spreadability
b, τ) good cadmium-free silver brazing alloy; 2) in cadmium-free silver brazing alloy, add an amount of tin (Sn), gallium (Ga) to reduce the fusing point of principal component alloy (Ag-Cu-Zn alloy), improve the wetability of cadmium-free silver brazing alloy on red copper, brass, carbon steel, stainless steel and nickel-base alloy simultaneously, add the crystal grain of rare-earth element cerium (Ce) simultaneously, improve the plasticity and the comprehensive mechanical property of cadmium-free silver brazing alloy with the neoteric cadmium-free silver brazing alloy of refinement.
The technical scheme that addresses the above problem is, 1), use commercially available silver, cathode copper, zinc ingot metal, tin slab, gallium, metallic cerium, proportioning on demand adopts that conventional intermediate frequency smelting furnace is smelted, casting, by extruding, drawing, promptly obtain needed solder wire material then; 2), according to producing needs, tin slab, gallium, metallic cerium can be smelted into alloy respectively in advance, add then in silver-copper-zinc alloy smelt, casting, by extruding, drawing, promptly obtain needed solder wire material again.
Technical characterstic of the present invention is, neoteric " cadmium-free silver brazing alloy that contains gallium and cerium ", chemical composition (mass percent) is 17.0%～21.0% copper (Cu), 16.0%～20.0% zinc (Zn), 3.0%～6.0% tin (Sn), 2.0%～5.0% gallium (Ga), 0.001%～0.10% cerium (Ce), all the other are silver (Ag).Solidus temperature at 605 ℃～615 ℃ scopes, liquidus temperature 635 ℃～645 ℃ scopes; Cooperate FB102 (QJ102) brazing flux, brazing material is following combination: red copper-brass, brass-carbon steel, stainless steel-nickel-base alloy, σ
b=180～350MPa scope, τ=160～300MPa scope.
Adopt conventional intermediate frequency smelting furnace to smelt, cast, by extruding, drawing, promptly obtain needed solder wire material then; The neoteric cadmium-free silver brazing alloy that contains gallium and cerium is object of reference with BAg50CuZnCd, cooperate the FB102/QJ102 brazing flux, during combinations of materials such as soldering red copper-brass, brass-carbon steel, stainless steel-nickel-base alloy, suitable with it to wetability, the spreadability of mother metal, the suitable with it (σ of brazed seam mechanical property
b=180～350MPa scope, τ=160～300MPa scope).The neoteric cadmium-free silver brazing alloy that contains gallium and cerium does not have the harmful element cadmium fully, has protected operator's health safety effectively, has eliminated the pollution to environment.The performance indications of solder (as solid-liquid phase line temperature, brazed seam mechanical property) and BAg50CuZnCd, BAg50CuZnCdNi solder are suitable, and neoteric solder is just applied at the refrigeration part production industry as the substitute of BAg50CuZnCd, BAg50CuZnCdNi solder.
