1. Suitable for flame welding, resistance welding, high frequency welding and furnace welding between various copper and copper alloys.
2. Solder paste can be applied manually to the area to be soldered, and can also be used for semi-automatic and automatic template printing and needle injection. It is efficient and simple, and can quantitatively control the amount of solder paste used, which greatly improves work efficiency and product yield, and also improves working environment.
3. Copper-phosphorus-based solder paste is widely used in the brazing and manufacturing of copper products such as copper tubes, copper alloy electric heating tubes, hardware parts, and various copper radiators. In the field of resistance brazing, it is widely used in resistance brazing of various electronic components, such as circuit breakers, electric meters and other components.
