Manganin

(ˈmæŋɡənɪn)
n
(Metallurgy) trademark an alloy of copper containing manganese (13–18 per cent) and nickel (1–4 per cent): it has a high electrical resistance that does not vary greatly with temperature and is used in resistors

A significant difference between the designs of these high-current shunts from known (for example, described in [6]) is the use in them instead of a thin-walled (with a thickness of not more than 0.3 mm) high-resistance manganin disk from which the drop in the pulsed voltage from the passage of a measured current pulse is taken, a disk of thickness of 1 to 2 mm from stainless steel 12X18H10T [10, 11].
Cabalin and Laserna [26] used pulsed laser deposition to coat silicon with manganin. They produced multielemental maps to monitor the coating constituents.
The wire is made from alloys such as NiChrome or Manganin; these have extremely low thermal coefficients of resistance (TCR) and excellent long-term stability.
The manganin pressure gauges record the voltage-time signals from which the pressure-time curves can be obtained through (1).
Manganin was developed about 1890 and is an alloy of copper, manganese, and nickel, nominally 84%, 12%, and 4%, respectively.
1) Standard resistor calibration: The 0.1 ohm standard resistor is a commercial, double-walled manganin resistor (17) manufactured in 1913.
The structure of this shunt includes a manganin measuring disk with a thickness [h.sub.s] [approximately equal to] 0.3 mm with an external diameter [D.sub.se] [approximately equal to] 80 mm, which determines the impulse resistance of the shunt, which is approximately [R.sub.S] [approximately equal to] 0.185 m[OHM] [+ or -] 1% [3, 7].
Resistance elements made from Manganin alloy combine precision with a very low temperature coefficient of resistance (TCR) allowing operation over a typical temperature range from -40[degrees]C to +60[degrees]C.
If worrying about the effect of barometric pressure changes on the lattice structure of your Manganin or Evanohm standard resistors is keeping you awake nights, help is on the way.
Heat-treated manganin wire resistors developed by Thomas incorporated hermetically-sealed, double-walled enclosures, with the resistance element in thermal contact with the inner wall of the container to improve heat dissipation.
