BÖHLER P848 is an iron-48% -nickel alloy with low thermal expansion for applications in the electronics industry, for measuring instruments (e.g. measuring rulers, scales), temperature measuring instruments and temperature-dependent controls, thermostats, thermobimetals and expansion controllers up to temperatures of 450°C. The main application is in glass-metal compounds with soft lead crystal and soda-lime glasses.
The minimum coefficient of thermal expansion of BÖHLER P848 is in the range of 30 to 400°C. Above the break point at slightly above 450°C, the coefficient of expansion increases sharply and at higher temperatures reaches the values usual for austenitic materials. Good low temperature properties.
