Existing welding material is generally two kinds on market：One kind is SAC, and another kind is tin-lead copper alloy.With 《The instruction of some harmful components used in regard to being limited in electronic and electrical equipment》(Restriction of Hazardous Substances, ROHS) policy execution for prohibiting lead instruction in the electronics industry, leaded soldering material can not meet height The environmental requirement of standard.And the application difficult point of SAC is not only to require that brazier temperature is higher than original metal 30 degree, And its cost is also high than tin-lead copper alloy by 25%, it is often more important that the raising of this temperature can substantially reduce the steady of exposure components and parts It is qualitative.Therefore, red brass is further studied.But, the oxidation of zinc prevents the application of red brass.
The content of the invention
The purpose of the present invention is for above-mentioned the deficiencies in the prior art, there is provided a kind of environment friendly tin zinc manganese copper for welding is closed Golden new material and preparation method thereof.The Alloy Materials can be played and prevent the purpose of zinc oxidation, and greatly reduce material The stability of welding carrier is also improved while cost.
For achieving the above object, the technical solution used in the present invention is as follows：
A kind of environment friendly tin zinc manganese copper alloy new material for welding, is made up of the component of following proportioning：Tin 32%；Manganese 1%；Zinc 31%；Balance of copper.
Invention further provides a kind of side for producing the above-mentioned environment friendly tin zinc manganese copper alloy new material for welding Method, comprises the following steps：
1) Xi ﹑ Xin ﹑ Meng ﹑ copper is placed in main frequency furnace according to proportioning, is heated to 1150-1200 degree, protected after being completely melt Temperature is to 1100 degree；
2) after the alloy liquid being completely melt is sufficiently stirred for graphite rod, cover high-purity flaky graphite powder to prevent Its oxidation, thickness is 25-30cm；
3) it is incubated after 1-1.5 hours, produces Spike direct-reading spectrometer with Germany and the sample taken out from main frequency furnace is entered Three composition inspections of row, to determine its alloying component within prescribed limit；
4) 1200 degree are warming up to further after insulation 30-35 minutes, again, and open the vibrating device of main frequency furnace, shaken Dynamic frequency be 1 time/second, adopt horizontal continuous casting method to be cast as a diameter of 25mm, length for 600mm solid alloy bar；
5) extruded using 800 tons of single action extruders, alloy pig heating-up temperature is 100-150 degree, extrusion temperature is 200 degree, Extrusion speed V=15mm/s, a diameter of 12mm of alloy bar, length are 2500mm after extruding, then with high accuracy wolfram steel thin skin Mould is by alloy bar peeling once to 11mm；
6) alloy bar after extruding is made annealing treatment with box-annealing furnace, annealing temperature is 80-100 degree, during annealing Between be 1-1.5 hours；
7) the drawing section that length is 100mm, a diameter of 8mm is made in alloy bar one end after the completion of annealing with head machine processed, After alloy bar multi-drawing and will be annealed with finishing die so as to ultimately become the welding wire that a diameter of 5mm, tolerance are +/- 0.05mm Base rod, is then cut into length for 500mm, the specification that tolerance is+1/-0mm by welding wire base rod；
8) pack and put in storage.
The invention has the beneficial effects as follows：
The present invention replaces lead element while original traditional welding material property is ensured, meets ROHS requirements. Add manganese element in the environment friendly tin zinc manganese copper alloy new material for welding of the present invention, the mesh for preventing zinc oxidation can be reached , the stability of welding carrier is also improved while material cost is substantially reduced.
