Good Morning Technet!
     
     Bill - the brazing alloy 72Ag/28Cu has an industry standard callout 
     per AWS A5.8: BAg8. I started digging through my references and then 
     stopped - you are asking for the physical properties of the braze 
     alloy itself and those don't typically show up in the standard 
     reference. I checked the ASM Handbooks and the AWS Handbook series but 
     neither contained the physical property data you are looking for. I 
     suggest you call:
     
     Handy & Harmon
     850 Third Ave
     New York NY 10022
     212-752-3400
     
     This phone number is old so you may have to make a couple of calls to 
     get to H&H. They are an industry leader in supplying brazing materials 
     and hopefully they have the data you are looking for. Good Luck.

Does anyone have CTE, thermal conductivity, and strength data for 
72Ag/28Cu brazing alloy?  I'm performing a thermal/stress analysis of a 
system that is cooling from solidification of the brazing alloy (800C) 
to room temp. and is then modified and cooled to -55C.  I'm sure the 
properties are temperature dependent, but room temperature data would 
get me in the ballpark.  Any help would be appreciated.
