PURPOSE:To provide a solder essentially composed of Pb, Sn, Zn and/or rare earth metal and In and/or Bi with a specifieb blending which enables the bonding of hard-to-solder material such as glass at a low temperature. CONSTITUTION:This solder is composed of 1-97.5% Pb by weight, preferably 80-95%, 1-97.5% Mn, preferably 5-30%, 0.05-15% Zn, and/or 0.01-15% rare earth metal, 0.1-50% In and/or 0.01-60% Bi as essential components. This rare earth metal preferably employs so-called cesium mesh metal composed of 86.8% Ce, 3;0% La, 4.0% Nd, and 6.2% Sm and Pr and impurities from an economical point of view. Slight addition of more than one kinds of Al, Si, Ti and Be can prevent tarnish on the surface of the solder. This solder is applicable to metal, crystalized glass alumina and the like besides glass. |
