The welding liquid can flow into the depth of the small brazing gap, so that the welded joint has higher strength and toughness, and the strength of the brazed joint can reach more than 90% of the base material.
Working temperature 600°C~900°C, reducing the risk of thermal deformation and brazing time.
The face-centered cubic (FCC) crystal structure of silver (Ag) enables it to undergo plastic deformation without cracking during welding, and silver is the metal with the best known conductivity (IACS 105%). Silver brazing alloys ensure conductivity through high silver content + low impurity control (oxygen content <0.01%).
Particularly suitable for replacing split air-conditioning copper pipes, household refrigerators, commercial refrigeration units, filters in refrigeration system accessories, water compressors, etc., to ensure a firm and reliable connection.
