研制出的三种低锡钎料的各项性能均与30/70、40/60及50/50高锡钎料相当。其中2号与3号钎料可以在完全不改变现有生产工艺与设备的情况下焊出优质水箱。低锡钎料比高锡钎料每吨便宜4～5千元。
Developed three kinds of low tin solder properties are 30/70, 40/60 and 50/50 high tin solder quite. Among them, No. 2 and No. 3 brazing filler metal can be welded out without changing the existing production process and equipment. Low tin solder than high-tin solder 4 to 5 thousand yuan per ton cheaper.
