Ofrod, oxygen-free copper rod for electrical applications

Oxygen-free copper rod obtained using vertical casting technology. The absence of oxygen allows for excellent drawability and low recrystallization temperature. It also avoids hydrogen embrittlement.

Ideal for applications requiring high conductivity and purity, which must be covered with elements that react with oxygen to cause hydrogen embrittlement, fire-resistant cables, automotive cables, electronic cables, Class 6 and 7 audio and video cables and for the manufacture of microwires for subsequent extrusion through the Conform®.
