Copper and zinc solder

　　 The copper and zinc solder is mainly used in the welding of copper, copper alloy, nickel, steel, and cast iron in the ways of gas blaze soldering, brine dipping soldering, high frequency soldering. The optimum gap in the joint is 0.025-0.1mm by using copper and zinc solder. The copper and zinc solder should pursue the shortest time by the method of oxygen-acetylene blaze to reduce the evaporation of zinc and formation of porous gap in the joint.
To see the table below about copper and zinc solder supplied by us.
