Horizon brass filler metal has good plasticity, higher melting point, it can be used for brazing copper, steel, ingot iron, nickle-base alloy, hard alloy et working with borax or gas brazing flux, flame, furnace and induction brazing etc methods can be adopted. It has a small quantity of silicon in filler metal for high-content zinc, when brazing, do not overheat to reduce the influences of zinc voltatilization on brazing seam compactness and human health.
