Silver Braze 60Sn10
Silver Braze 60Sn10 Technical Data
Uses
Silver Braze 60Sn10 is a silver based brazing filler metal used in making of low temperature seals in vacuum tube components. Silver Braze 60Sn10 is often used in brazing of ferrous and non-ferrous alloys in a controlled atmosphere or vacuum furnace applications without the use of flux. It is recommended for brazing of heat exchanges exposed to salt water in marine environment. Salt water exposure may cause dezincification in braze alloys containing zinc, particularly in joints involving copper-nickel tubing.
Brazing Characteristics
Silver Braze 60Sn10 can be used where low volatiles is not a requirement. This filler metal can be used successfully to braze in hydrogen atmospheres without the use of flux. The tin content of this filler metal improves its wetting characteristics on ferrous base alloys over in comparison to binary silver copper braze filler metals. The addition lowers the melting range versus binary silver copper compositions. There is some tendency for the filler metal to liquate, but this is minimized by rapid heating to brazing temperature.
Properties of Brazed Joints
The properties of a brazed joint are dependent upon the base metal, joint design and brazing technique. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for silver base alloys fall within 0.0015 in. - 0.002 in. (0.038 mm - 0.051 mm.) range.
