The welding liquid flows deeply into small brazing gaps, enabling joints to reach more than 90% strength of the base material with high toughness.
Working temperature is optimized between 600°C and 900°C, reducing the risk of thermal deformation and minimizing total brazing time.
Face-centered cubic (FCC) crystal structure of Ag enables plastic deformation without cracking. High silver content and low impurities (oxygen <0.01%) ensure superb conductivity.
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.
