Hi all!
Was searching online for some good low EMF shorting straps, and came up pretty empty handed. The only easily found examples were nickel plated brass, which seem to be less than ideal for below e-6. So, I have decided to have some solid copper ones milled and might have extras made if there is enough interest.
I'm thinking .032" to .050" thick, but have two basic alloys to choose from. C101, or C110 in various tempers. C101 is "oxygen free", but C110 reportedly has the highest conductivity of all copper alloys so that on the surface would seem the better choice. I don't think the level of tempering will effect conductivity or any thermal characteristics, but defer to you experts on this??

At face value, it would seem the hardest temper available would be ideal, mechanically speaking.
Then there's the physical design... I'm leaning more towards "B" or "C" in the below image, what would your preference be?
