PURPOSE:To obtain Al solder enabling satisfactory soldering at a low temp. in a nonoxidizing atmosphere without using a flux by preparing solder contg. a specified percentage of Li, Mg, Mn, Ca, Al and Zn. CONSTITUTION:Low temp. Al solder consisting of, by wt., <=3% of at least one of Li, Mg, Mn and Ca, 2-8% Al and the balance Zn with inevitable impurities or further contg. 1-6% Ag is prepared. Desirable solder consists of 2-8% Al, 1-6% Ag, at leat one of <=1% Li, <=2% Mg, <=0.5% Mn and <=1.5% Ca or 0.5-2% in total of Li and Mg, Mg and Mn, or Ca and Mg, and the balance Zn. Thus, an Al alloy can be soldered well at a low temp. without using a flux. |
