40% double "O" welding ring

1) the double "O" welding ring has Low melting point 2)welding ring with good flow-ability 3) the ring has stable quality  BAg40CuZnIn silver welding ring is one kind of the silver-copper-zinc alloy welding materials whose main  material includes silver, copper, zinc and indium. Among them, the percentage of silver in the welding ring reaches 40.The adding of zinc can restrain the temperature from rising and reduce the cost of filler metal. The adding of indium decreases the melting point of the welding ring. Our company has hundreds of production specifications in copper base alloy welding materials, silver welding materials, scaling powder and other intermediate temperature welding materials. This welding ring will not destroy the parent metal but fill the inter-space between those parent metals excellently due to its good flow-ability. Its various specifications will meet different customers’ need.
