as solder,cu-zn alloy mainly used for gas flame soldering,high-frequency soldering,salt bath brazing,soldering copper alloy,nickel,steel and cemented alloy ect.
oil patch and oxide in the part of being soldered and on the surface of brazing alloy must be cleared totally before soldering,the best clearance of joint is 0.025-0.1mm. the usage of soldering flux at the same time can bring you an excellent joint
