Temperature Compensating AlloysTC 30/TC 32 - Temperature Compensating Iron-Nickel alloys are used for applications where magnetic shunts are used for temperature compensation. Most frequently it is used for temperature compensation in energy meters, speedometers and temperature regulation devices. Even after very high variations in temperature, no changes have been found in the magnetic properties of these alloys.
TC 30, 32 is supplied in the following conditions:
| Alloy | Nickel | Mangnese | Iron |
|---|---|---|---|
| TC 30 | 30 | Max 1.0 | Bal |
| TC 32 | 32 | Max 1.0 | Bal |
Wires: 10.0 mm diameter to 0.15 mm diameter. (0.3937” diameter to 0.0059” diameter).
Strips: Width 0.4 - 100mm, Thickness: 0.10mm and above.
| Alloy | Curie Temperature | Density | Electrical Resistivity |
|---|---|---|---|
| TC 30 | 148°C | 8.19 gm/cm³ | 80 μΩ-cm |
| TC 32 | 199°C | 8.11 gm/cm³ | 80 μΩ-cm |
| Difference in magnetization at different temp. at 100 Oe or 8000 Amp. Per Meter field strength. |
B-12.5 – B0 > 60mT B0 – B25 > 120mT B25 < 300mT B25 – B50 > 100mT B50 > 40mT |

Minimum: -200°C (-328°F) but below –120°C (-184°F) slight magnetism may occur.
Maximum: 340°C (644°F) For continuous operation. Can be taken up to 1000°C.
For better mechanical handling, stress relieve at 450 - 480°C for 60 minutes is recommended.
