1060　aluminum　alloy　and　T2　copper　with　the　thickness　of　3　mm　are　joined　by　means　of　laser　penetration-brazing　(LPB)　with　a　Yb:YAG　disc　laser.　The　mechanical　properties　of　the　joint　are　measured　by　microhardness　and　tensile　tests.　The　microhardness　of　the　weld　is　higher　than　that　of　aluminum　and　copper　base　metals,　respectively,　due　to　the　formation　of　fine　grains　and　hard　Al2Cu　and　Al2Cu3　intermetallic　compounds.　The　results　of　the　tensile　tests　for　welded　samples　are　variational　under　the　same　parameters.　The　maximum　failure　strength　for　tensile　test　is　100.6　MPa.　The　failure　occurres　at　aluminum　side.　The　minimum　failure　strength　is　94.5　MPa.　The　failure　happens　close　to　the　interface　due　to　the　hardness　gradient　and　brittle　intermetallic　compounds.
