Abstract
A non-Cd Ag solder containing Ga, In, Nd and Ce is proportionally prepared from Cu, Zn, Sn, Ga, In, Nd, Ce and Ag through smelting, casting or horizontal conticasting, extruding and drawing to obtain Ag solder wire.
Description
Technical field
The invention belongs to the welding material class, be specifically related to a kind of cadmium-free silver brazing alloy that contains gallium, indium and rare earth neodymium and cerium.
Background technology
At present, the welding filler metal that uses in welding process is generally and contains cadmium brazing silver alloy BAg35CuZnCd and BAg40CuZnCd both at home and abroad, all contains a large amount of " poisonous element " cadmiums (Cd) in its chemical composition.Owing to contain the toxicity of cadmium solder, all begin to forbid this be in the application in the electric material of cadmium material that contains both at home and abroad.Yet the substitute products that do not contain cadmium that also do not have a kind of suitable superior performance in the market.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of cadmium-free silver brazing alloy that contains gallium, indium and rare earth neodymium and cerium poisonous element cadmium, good, the alternative BAg35CuZnCd of brazing property and BAg40CuZnCd that can the welding position in brazing process and after the soldering do not have fully is provided.
In order to achieve the above object, a kind of cadmium-free silver brazing alloy that contains gallium, indium and rare earth neodymium and cerium of the present invention, chemical composition (mass percent) is 30.0%～40.0% copper (Cu), 28.0%～32.0% zinc (Zn), 0.01%～1.0% tin (Sn), 0.1%～2.0% gallium (Ga), 0.1%～2.0% indium (In), 0.001%～0.10% neodymium (Nd) and 0.001%～0.10% cerium (Ce), all the other are silver (Ag).
The present invention adopts commercially available silver, cathode copper, zinc ingot metal, tin slab, gallium, indium metal, neodymium metal, metallic cerium, proportioning on demand, adopt the conventional smelting of intermediate frequency smelting furnace, casting or adopt the horizontal casting mode to obtain casting rod (ingot casting), to cast rod (ingot casting) then by extruding, drawing, promptly obtain needed solder wire material; The present invention also can smelt into alloy respectively in advance with tin slab, gallium, indium metal, neodymium metal, metallic cerium according to producing needs, adds then in silver-copper-zinc alloy and smelts, casts, and by extruding, drawing, promptly obtains needed solder wire material again.
The cadmium-free silver brazing alloy solidus temperature that contains gallium, indium and rare earth neodymium and cerium of the present invention at 680 ℃～690 ℃ scopes, liquidus temperature in 755 ℃～770 ℃ scopes (having considered experimental error).Cooperate FB102 (QJ102) brazing flux, brazing material is following combination: when red copper-brass, brass-carbon steel, stainless steel-nickel-base alloy, the mechanical property of soldered fitting is respectively at σ
b=170～360MPa scope, τ=170～310MPa scope.
The present invention mainly solves following two key technical problems: 1) develop silver solder no cadmium, alternative BAg35CuZnCd and BAg40CuZnCd, by optimizing the chemical composition of " cadmium-free silver brazing alloy that contains gallium, indium and rare earth neodymium 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), indium (In) 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 rear earth element nd (Nd) and cerium (Ce) crystal grain simultaneously, improve the plasticity and the comprehensive mechanical property of cadmium-free silver brazing alloy with the refinement cadmium-free silver brazing alloy.
The present invention adopts conventional intermediate frequency smelting furnace to smelt, cast or adopts the horizontal casting mode to obtain casting rod (ingot casting), will cast rod (ingot casting) then and pass through extruding, drawing, promptly obtains needed solder wire material; The cadmium-free silver brazing alloy that contains gallium, indium and rare earth neodymium and cerium of the present invention is an object of reference with BAg35CuZnCd and BAg40CuZnCd, cooperate the FB102/QJ102 brazing flux, during combinations of materials such as soldering red copper-brass, brass-carbon steel, stainless steel-nickel-base alloy, wetability, spreadability to mother metal are suitable with it, the suitable with it (σ of brazed seam mechanical property
b=170～360MPa scope, τ=170～310MPa scope); The cadmium-free silver brazing alloy that contains gallium, indium and rare earth neodymium and cerium of the present invention does not have the harmful element cadmium fully, has protected operator's health safety effectively, has eliminated the pollution to environment; Solder of the present invention can be used as the substitute of BAg35CuZnCd and BAg40CuZnCd solder and applies at the refrigeration part production industry.
