These lower-resistivity Jelliff alloys provide a graduated series (the grade numbers indicate resistivity in ohms/c.m.f.) for use in low-ohmage units, including fixed resistors, rheostats, relay windings, and “heater cord.” This wide choice of resistivities also allows the use of the most desirable diameter for proper resolution in potentiometers.
Bare wire will be provided unless other tolerances are required.
