銅合金釬料?Copper-alloys brazing filler metal
?
? ?銅鋅合金釬料主要用于銅與銅合金、鎳、銅、鑄鐵、硬質合金等的氣體火焰釬焊、高溫釬焊和鹽浴浸漬釬焊。用氧-乙炔火焰釬焊時，用氧化焰加熱可減少鋅的蒸發，釬焊加熱時間力求**短，并避免過熱，以免接頭處過分氧化形成多孔焊縫。釬焊接頭的間隙為0.025-0.1毫米，釬焊時需配合釬劑方可獲得良好的釬縫。
? ?Copper-Zinc brazing alloys are suitable for gas-flame brazing,high temperature brazing,salt bath dip brazing of copper and copper alloys,nickel,cast iron and hard alloys.While brazing by oxyacetylene,to heat with oxidized flame quickly can lessen evaporation of Zinc and prevent gas porosity due to over-oxidization.The optimum joint gap should be 0.025-0.1mm.Flux is also necessary for good seam.
