BALCO* / 120 OHM ALLOY
*BALCO is a Registered Trademark of Carpenter Technology Corporation.
Nominal Analysis:
Nickel: 70%
Iron: 30%

DESCRIPTION:
Balco has been used in thermometer bulbs and other applications that requirea high temperature coefficient of resistance. It has a temperature coefficient similarto nickel, and twice the resistivity. The slope of the temperature resistancecurve is almost straight from -70 Deg. to 600 Deg. C (-94 Deg. to 1112 Deg. F).Balco conforms to ASTM specification B-267, Alloy Class 8.

Nominal Analysis:

Copper	84%
Manganese	12%
Nickel	4%

Note: Chemical analysis varies slightly with manufacturer.
Manganin has a resistivity of 290 ohms per circular mil foot and a low thermal
emf vs copper (not exceeding +3.0 microvolts per degree C between
0 and 100 degrees centigrade) and a nominal temperature coefficient of
resistance of +\- 15 ppm per degree C between 15 and 35 degrees C. The
peak in the resistance temperature curve is approximately 25 degrees C.
Conforms to ASTM B-267 Class 6.
