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

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.
