Silver-based copper zinc environmental protection solder (silver solder) grade and performance profile


Brand Performance Introduction


(1) HAG-18BSn 18% silver is a silver, copper, zinc, tin alloy, with a slightly higher melting range, good wettability and filling properties, and an economical price. Can weld copper, copper alloy, steel and other materials. Melting point 770-810 degrees Celsius.


(2) HAG-25B contains 25% silver equivalent to the national standard BAg25CuZn and L302. It is silver, copper, zinc, and alloys. It has good wetting and filling properties, but its melting point is slightly higher and it can be used to weld copper, steel and other materials. Melting point 700-800 degrees Celsius.


(3) HAG-25BSn containing 25% silver equivalent to American Standard AWS BAg-37, is silver, copper, zinc, tin alloy, melting point is lower than HAg-25B, improves the wettability and filling. Weldable copper, steel and other materials. Melting point 680-780 degrees Celsius.


(4) HAG-30B 30% silver content equivalent to the American standard AWS BAg-20, the national standard BAg30CuZn, is a silver, copper, zinc alloy, a slightly higher melting point, joints have good toughness, brazing copper, copper alloys, steel, etc. material. Melting point 677-766 degrees Celsius.


(5) HAG-35B contains 35% silver equivalent to American Standard AWS BAg-35, is a silver, copper, zinc alloy, medium melting temperature, joints have good toughness, brazing copper, copper alloys, steel and other materials. Melting point 621-732 degrees Celsius.


(6) HAG-35Sn containing 35% silver is equivalent to the national standard BAg34CuZnSn, is a silver, copper, zinc, tin alloy, medium melting temperature, good fluidity, more suitable for welding of ferritic and non-ferritic steel . Melting point 620-730 degrees Celsius.


(7) HAG-40B 40% silver is silver, copper, zinc, alloy, has good fluidity, permeability and toughness, melting point 677-732 degrees Celsius.


(8) HAG-40BNi 40% silver is silver, copper, zinc, nickel alloy, equivalent to American Standard AWS BAg-4, with good corrosion resistance, suitable for stainless steel welding and nickel-base alloy and tungsten carbide Welding, melting point 670-780 degrees Celsius
