Used as main brazing materials are AgCu7.5, AgCu25, AgCu28, AgCu55, etc., and the AgCu28 is widely used.They have good conductivity, fluidity and wettability, and is widely used in the electric vacuum industry. Due to the low resistance to long-term load under high temperature, it is only suitable for brazing parts whose working temperature is lower than 400ºC.
Used as coins and decorations. The alloys used as coins are AgCu7.5, AgCu8, AgCu10, etc.; the alloys used as decorations are AgCu8.4, AgCu12.5, etc
