Tungsten Copper Rod CTE 310

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/℃. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html 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…
