Applications: The principal use to date of Lithobraze 925 has been the brazing of honeycomb panel sections. It can be used for general purpose furnace brazing of stainless steels where flux must be avoided.
Characteristics: Lithobraze 925 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 such as 17-7PH, PH15-7Mo and AM350.
The use of Lithobraze 925 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 a hydrogen or inert atmosphere of low dew point (-70EF/-55EC or drier). Argon is the most commonly used inert gas.
