OFE Wire

Oxygen-free copper is the purest form of the metal, offering unparalleled thermal and electrical conductivity as well as superior weldability. As a conductor, it generates much less internal heat than other copper grades and it suffers a much lower decrease in conductivity at high temperatures.

Luvata is the leading supplier of oxygen-free copper, and capable of reaching the highest levels of purity available. By definition, oxygen-free copper has below 10ppm oxygen. Luvata is able to supply it at fewer than 2ppm with very high consistency and uniformity.

Our OFE-OK® wire is used around the world wherever the ultimate properties in terms of purity or electrical conductivity are needed.
