Product Description

 

Oxygen Free Electronic (C10100)

Oxygen-free copper is typically specified according to the ASTM/UNS database.^[4] The UNS database includes many different compositions of high conductivity electrical copper. Of these, three are widely used and two are considered oxygen-free:

• C10100 - also known as oxygen-free electronic (OFE). This is a 99.99% pure copper with 0.0005% oxygen content. It achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment. Silver (Ag) is considered an impurity in the OFE chemical specification. This is also the most expensive of the three grades listed here.
• C10200 - also known as oxygen-free (OF). While OF is considered oxygen-free, its conductivity rating is no better than the more common ETP grade below. It has a 0.001% oxygen content, 99.95% purity and minimum 100% IACS conductivity. For the purposes of purity percentage, silver (Ag) content is counted as copper (Cu).
• C11000 - also known as electrolytic-tough-pitch (ETP). This is the most common copper. It is ubiquitous in electrical applications. ETP has a minimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has 0.02% to 0.04% oxygen content (typical). Most ETP sold today meets or exceeds the 101% IACS specification. As with OF copper, silver (Ag) content is counted as copper (Cu) for purity purposes.
