Thanks George,
I'll play around a little and see what sticks.
Gotta love these crazy alloy names:  German-Silver, Nickel-Silver, etc.  And not a lick of silver in it.

Andy,

I somewhat agree with Bev that some of the no-clean solder pastes and fluxes should allow you to solder to Nickel-Silver.  I disagree that is commonly referred to as German Silver.  Since he's from Canada it may commonly be referred to there and in Europe as German Silver but in my 40 years in telecommunication equipment soldering I've commonly heard it referred to as Nickel-Silver.

I also agree with Phil, any flux that contains zinc chloride and HCl should solder almost any metal.

You might also want to try soldering with a standard WSF and you should have success.

My other recommendation is to do solderability testing in your analysis lab and she what flux works

Andy,
This is commonly referred to as German Silver.  I have seen it often used for RF cans.  It should solder fine with your usual non-clean solder pastes.
However, will the can warp?  We set specific maximum sizes for different shapes of RF cans (not that the designers would always listen).  We also measured can warpage using shadow moiré.

Subject: [TN] Soldering to 'Nickel-Silver'

Hi Folks,
Has anyone had experience soldering to 'Nickel-Silver' 
This is a ternary alloy with approximately 60% Cu, 20% Ni, 20% Zn.

If so, are there any special considerations such as flux type, pre-tinning etc...

Best Regards,
