Mark,
Here are the values from table C-1, in Volume 2 of my book Robust
Electronic Reference Design (I sent the camera-ready manuscript to
Kluwer Academic Publishers on October 2, but it isn't in print yet):

Copper Ur = 1.
Gold Ur = 1.
Molybdenum Ur = 1.
Tungsten Ur = 1.
Nickel Ur = 50 to 2,000, nominally 100, with a saturation magnetic
flux    density of 6,000 to 6,500 teslas.
