The applications of DY-Ag2 50% silver brazing filler metal are mainly concentrated in the following aspects:

1. Refrigeration System Welding: DY-Ag2 silver brazing wire is suitable for welding copper-to-copper pipe joints in refrigeration systems of air conditioners, refrigerators, and freezers. This filler metal has a brazing temperature range of 732-816°C, good brazing process performance, low silver content, and relatively low cost.

2. Machinery, Electronics, Home Appliances, Hardware, Automotive Parts, and Other Industries: The 50% silver brazing filler metal (such as BAG-50B) is suitable for brazing copper and copper alloys, steel, and other materials. The brazed joints made with this filler metal can withstand multiple vibration loads and are suitable for brazing band saws. Additionally, it exhibits good flowability and gap-filling capability, high joint strength, and excellent resistance to impact loads.

3. Special Material Welding: The 50% silver brazing filler metal (such as BAG-50SnNi) is suitable for welding copper and copper alloys, steel and stainless steel, quenched and tempered steel, Kovar alloy, and other materials. The brazed joints produced with this filler metal have a smooth surface and higher strength compared to conventional silver brazing materials.
