The applications of DY-Ag15 50% silver solder strip are mainly concentrated in the following aspects:

1. Welding Materials:

   • Copper and Copper Alloys: DY-Ag15 50% silver solder strip has good fluidity and filling ability, making it suitable for brazing copper and copper alloys. For example, HL209 silver solder rod contains 2% silver, equivalent to the American standard AWS BCuP-6 and the Chinese standard BCu91PAg, with a melting point of 645-790°C. It is widely used in industries such as air conditioning, refrigeration, and electromechanics.
   • Steel and Hard Alloys: The 820 silver solder strip contains 15% silver, equivalent to the American standard AWS BCuP-5, Chinese standard BCu80AgP, and L204. It features good joint plasticity and improved conductivity, making it particularly suitable for uneven gap scenarios, with a melting point of 645-800°C.

2. Industrial Applications:

   • Electromechanical Industry: HAG-50B silver solder rod contains 50% silver, equivalent to the American standard AWS BAg-6 silver solder rod, Chinese standard BAg50CuZn silver solder rod, and L304 silver solder rod. It is suitable for welding materials in electronics, food machinery, and applications subject to vibrational loads, with a melting point of 690-775°C.
   • Food Machinery: HAG-50B silver solder rod is also suitable for welding food machinery, ensuring the strength and corrosion resistance of welded parts.
   • Stainless Steel Brazing: HAG-50BNi silver solder rod contains 50% silver, equivalent to the American standard AWS BAg-24 silver solder rod. It is a silver, copper, zinc, and nickel alloy, cadmium-free, and most suitable for stainless steel brazing, improving resistance to crevice corrosion, with a melting point of 660-707°C.

3. Special Applications:

   • Stainless Steel and Nickel-Based Alloys: HAG-40BNi silver solder rod contains 40% silver and is a silver, copper, zinc, and nickel alloy, equivalent to the American standard AWS BAg-4. It offers good corrosion resistance and is suitable for welding stainless steel, nickel-based alloys, and tungsten carbide, with a melting point of 670-780°C.
