Thanks Bev and Phil,
That's exactly what I was looking for.  
I had never tried soldering to this material and I didn't know what to expect.  The material vendor spec sheet said that 'it solders great'.  A quick dip-and-look soldering says 'not so much'.  I'm using Alpha 100-40 Type R and SAC305(ish) at 255C.   
So, it 'should' solder well and perhaps I'll try, try again.

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...
