6, BCu89AgP( BCuP-3): Ingredients P:5.8-6.70%, Silver4.80-5.20%, copper: margin. Melting temperature645-788 ℃, with low melting point, the ductility and conductivity of the solder are improved, and the fluidity is general, which is suitable for copper and brass parts with large brazing gap;

7, BCu88AgP( HL205/BCuP-7): Ingredients P:6.50-7.00%, Silver4.80-5.20%, copper: margin. Melting temperature645-780 ℃, the melting point is low, the ductility and conductivity of the solder are improved, and the fluidity is better B- Cu89PAg, generally used for brazing copper and brass parts with large gap;

8, BCu87PAg( BCuP-4): Ingredients P:7.0-7.5%, Silver5.80-6.20%, copper: margin. Melting temperature645-718 ℃, low melting point, the solder has low melting point, good fluidity, can solder joints with small gap, and is generally used for brazing copper and brass parts;

9, BCu80PAg( HL204/BCuP-5): Ingredients P:4.80-5.30%, Silver14.50-15.50%, copper: margin. Melting temperature645-815 ℃, the melting point is low, and the ductility and conductivity of the solder are further improved, which is used for welding requirement ratio HL205(5% silver) copper and brass parts with brazing material high and large joint gap.

10, BCu60ZnSn- R(S221/RBCuZn- A): component copper:59.00-61.00%, tin0.80-1.20%, Silicon:0.15-0.35%, zinc: margin. Melting temperature890-905 ℃, the solder has a high melting point and can be used for welding carbide-tipped tool, molds and mining tools. And can be replaced H62 solder to obtain relatively dense weld, and can be used as welding wire for gas welding brass
