German silver         
¦ noun a white alloy of nickel, zinc, and copper.
German Silver         
An alloy of copper, 2 parts, nickel, 1 part, and zinc, 1 part. Owing to its high resistance and moderate cost and small variation in resistance with change of temperature, it is much used for resistances. From Dr. Mathiessen's experiment the following constants are deduced in legal ohms:   Relative Resistance (Silver = 1),      13.92
  Specific Resistance at 0° C. (32F.),   20.93 microhms.
  Resistance of a wire,
  (a) 1 foot long, weighing 1 grain,      2.622   ohms.
  1 foot long, 1/1000 inch thick,       125.91     "
  1 meter long, weighing 1 gram,          1.830    "
  1 meter long, 1 millimeter thick,       0.2666   "
  Resistance of a 1 inch cube at 0°C. (32° F.),   8.240 microhms.
Approximate percentage increase of resistance per 1° C. (1.8° F.) at about 20° C. (68° F.), 0.044 per cent.

Wikipedia

Nickel silver

Nickel silver, Maillechort, German silver, Argentan, new silver, nickel brass, albata, alpacca, is a copper alloy with nickel and often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc. Nickel silver does not contain the element silver. It is named for its silvery appearance, which can make it attractive as a cheaper and more durable substitute. It is also well suited for being plated with silver.

A naturally occurring ore composition in China was smelted into the alloy known as paktong or báitóng (白銅) ("white copper" or cupronickel). The name "German Silver" refers to the artificial recreation of the natural ore composition by German metallurgists. All modern, commercially important, nickel silvers (such as those standardized under ASTM B122) contain significant amounts of zinc and are sometimes considered a subset of brass.
