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...
