Thermal Expansion Coefficient (TEC)
The Thermal Expansion Coefficient for a given material is a measure of the fractional change in length per degree change in temperature. The coefficient itself slightly changes with temperature and is most commonly reported as an average value for the temperature range of interest, typically room temperature to 100° C. A ranking for a group of materials available from Hamilton Precision Metals follows.

Electrical Resistivity
Resistivity characterizes a metal’s inherent capacity to support the flow of electrical current.
The measured resistivity is the inverse of electrical conductivity and is expressed in Microhm•cm.
Conversion to other common units for resistivity are as follows:
1 Microhm•cm = 6.015 ohms CMF (ohms circular mil per foot)
1 Microhm•cm = 4.724 ohms SMF (ohms square mil per foot)

Thermal Conductivity
Thermal Conductivity describes the inherent capacity of a metal to support the flow of thermal energy.
Thermal Conductivity is expressed in W/m•K (Watts per meter degree Kelvin).
Conversion to other common units of Thermal Conductivity are as follows:
1 W/m•K = .5782 BTU • FT/HR • FT2 • °F
1 W/m•K = .0024 Cal/cm.s. °C
