Silver Braze 92.5

Silver Braze 92.5 Technical Data


Silver Braze 92.5 has been used in the brazing of honeycomb panel sections. It can be used for general purpose furnace brazing of stainless steels where flux must be avoided. 

Brazing Characteristics

Silver Braze 92.5 is lithium modified sterling silver, designed primarily for fluxless furnace brazing of stainless steels. This alloy has been widely used for brazing honeycomb airframe structures made of precipitation hardening stainless steels. The use of Silver Braze 92.5 permits taking advantage of the maximum panel strength afforded by free node flow. This alloy is not suitable for torch brazing in air but must be used in hydrogen or inert atmosphere of low dew point (-170F/-55C or drier). Argon is the most commonly used inert gas.  

Properties of Brazed Joints

The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design, metallurgical interaction between the base metal and the filler metal. Joints brazed with Silver Braze 92.5 have been used for applications where operating temperatures where operating temperatures were intermittently as high as 900F (480C). When continuous elevated temperature exposure to oxidizing conditions is to be expecting (1000 hours or more), the maximum operating temperature should be reduced to 500F (260C). Joints made on heat resistant alloys with these filler metals are much more resistant to interface corrosion than flux brazed joints. Final acceptance should be based on tests made under the anticipated service conditions.
