Hi Dave

The drawing is dated 1992, but it may be one of these legacy things that
sticks from drawing to drawing...

Hi Graham - what year is the drawing call out? I need a time reference
to narrow my search?

[TN] Old reference for silver solder - what's it cross ref to?

 

		




Hello Technet
I seem plagued with strange solder questions these days.  Can somebody
help with a cross-reference from an old solder callout to what this
would be referred to as now?  I have a drawing that references:
"QQ-S-571 alloy 94LTS Type WRAP3", and refers to it as "silver solder".

I can get the last version of QQ-S-571 (rev F, before it was cancelled
and J-STD-006 adopted), but I do not see this type of callout.  Does
anyone have something that will tell me what's in this solder?

Thanks!
