The invention relates to cadmium-free and low-silver filler metal containing manganese and tin and a production method of the cadmium-free and low-silver filler metal, which are suitable for brazing copper alloys such as stainless steel, red copper and brass. The cadmium-free and low-silver filler metal is prepared from the following components in percentage by weight: 13 to 19 percent of Ag, 25.5 to 38 percent of Zn, 35 to 40 percent of Cu, 1.0 to 5.5 percent of Sn, 7 to 14 percent of Mn, 0.5 to 3.0 percent of Ni and 0.001 to 0.3 percent of trace element R, wherein the trace element R is prepared from one or more of lanthanum, cerium, silicon and antimony. The invention further provides the production method of the cadmium-free and low-silver filler metal containing the manganese and the tin. The production method comprises the following steps of adopting an intermediate frequency melting furnace to melt and cast; during melting, adding the components according to the sequence of Ag, Cu, Sn, Zn and Cu-Mn for melting; then adding a trace Cu-R alloy; finally, producing the cadmium-free and low-silver filler metal containing the manganese and the tin by techniques such as casting, saw stripping, extruding, drawing, forming and cleaning. The silver content of the cadmium-free and low-silver filler metal containing the manganese and the tin, disclosed by the invention, is lower than that of 20 percent of silver filler metal; the cadmium-free and low-silver filler metal containing the manganese and the tin does not contain cadmium element and is lower in melting temperature; and a multicomponent silver filler metal with good processing performance is used for brazing the red copper, the brass and the stainless steel.
