Tungsten Copper Rod CTE

Tungsten copper rod CTE (Coefficient of Thermal Expansion) represents the variation of length by temperature changes under constant pressure. And the unit of metal CTE is 1/℃.

Tungsten copper rod CTE can be divided into linear expansion coefficient α, superficial expansivity β and volume expansion coefficient γ. When the temperature change is not very large, α becomes a constant, it can represent both solid and liquid volume expansion as follow: Vt = V0 (1 + 3αΔT), Vt = V0 (1 + 0.00367ΔT) for ideal gas; Vt and V0 represent the volume of end state and initial state individually.
