Temperature coefficient of linear expansion
| Alloy | Density g/cm³ | t° melting point: | t° annealing: | TKLR (0-100°C) |
| Alumel | 8,67 | 1440°C | 950°C | 12-10-6 K-1 |
| Kopel | 8,9 | 1150°C | 800-850°C | 14-10-6 °C-1 |
| Constantan | 8,9 | 1250°C | 950°C | 14-10-6 °C-1 |
| Chromel | 8,7 | 1420°C | 800 - 900°C | 13,1-10-6 K-1 |
Testing
Alloys must be subjected to tests - tensile, and hydrostatic or non-destructive electrical test. The material must meet the required mechanical properties - tensile strength, yield strength, relative elongation.
