Oxygen free copper, also known in Europe as Cu-OF or CW008A to EN13601.

Composition: Copper 99.95 % min.

Hardness: B30 – 40

Conductivity: 101 %

Tensile strength: 25 – 40 Ksi

In simple terms the thermal conductivity of pure copper is about 400 watts per meter kelvin. This means that a plate of copper with area A and thickness L whose faces are kept at a constant relative temperature difference of deltaT Kelvin will conduct heat at a rate of 400.A/L.deltaT joules per second.
