Table below shows the mean coefficient of Thermal expansion and Linear Thermal expansion for Group 1 and Group 2 materials.
A = Mean Coefficient of Thermal Expansion, 10-6 mm/mm/°C.
B = Linear Thermal Expansion, mm/m in going from 20°C to indicated temperature.
The data in this table does not imply suitability of material for the selected temperature and needs to established separately.
