摘要： The invention, which enables wider use to be made of soft-soldering techniques, concerns an alloy, in particular a solder alloy, a method of joining workpieces by soldering using the solder alloy and the use of the alloy for soldering. The alloy proposed is characterized in that it contains at least 1 % by wt. of an element or a mixture of elements from sub-group IVa and/or Va in the periodic table, at least 0.01 % by wt. of an element or a mixture of elements from the lanthanide series; optionally at least 0.5 % of silver or copper or indium or a mixture silver and/or copper and/or indium; and optionally at least 0.01 % by wt. of gallium, the remainder consisting of tin or lead or a mixture of tin and lead plus, as applicable, the usual impurities. The alloy proposed can be used as solder in oxygen-containing atmospheres such as air, can be used at relatively low temperatures and efficiently wets normally difficult to wet surfaces such as ceramic surfaces. In a further embodiment of the invention, the solder alloy can be used without flux.
