Nickel

A metal; one of the elements; atomic weight, 58.8 ; equivalent, 29.4;
valency, 2; specific gravity, 8.8. It is a conductor of electricity.
Relative resistance, annealed (Silver = 1),   8.285
Specific Resistance,                         12.47   microhms.
Resistance of a wire
(a) 1 foot long, weighing 1 grain,      15.206   ohms.
(b) 1 foot long, 1/1000 inch thick,     74.963    “
(c) 1 meter long, weighing 1 gram,       1.060    “
(d) 1 meter long, 1 millimeter thick,     .1587   “
Resistance of a 1-inch cube,             4.907   microhms.
Electro-chemical equivalent, (Hydrogen = .0105)   .3087   mgs.

It is strongly paramagnetic, but loses this quality at 350º C. (662º F.)

It is important as a constituent of German silver, an alloy much used
for resistance coils.
