PURPOSE : A low temperature brazing alloy containing cerium which lowers an implementation temperature as much as 10%% as compared with a conventional brazing alloy during a brazing operation by containing a rare earth metal of cerium in a composition for a copper phosphorous brazing alloy is provided. CONSTITUTION : A copper phosphorous brazing alloy containing cerium comprises 4.8 to 7.5%% of phosphorous(P), 0.2 to 20%% of cerium(Ce) and the balance of copper(Cu). The copper phosphorous brazing alloy further comprises 1.8 to 15.5%% of silver(Ag). The copper phosphorous brazing alloy further comprises 2.5 to 7.5%% of tin(Sn). © KIPO 2007
