Oxygen-Free High Conductivity Copper 99.993 pure

Product Details

A brief overview of how oxygen-free high conductivity copper is made, its key features and benefits, and its main application areas.If you’re wondering what oxygen is doing in copper in the first place, there are two main reasons. First, pure copper is rarely found in nature, but is usually combined with other elements in the form of copper ores, some of which are oxygen-containing copper oxides, such as cuprite, malachite or azurite

Here are four of the most important:

Electrical conductivity of 102% IACS. OFHC has the best electrical conductivity of all coppers and is used for applications with the most demanding requirements.

• Thermal conductivity of 386-394 W/m°C. The removal of heat is essential for the efficient performance of electrical/electronic components; OFHC copper is the best choice for this function.Very high purity (99.99%). Any impurities present in copper will vaporise in vacuum conditions. This is avoided in OFHC copper because of its high purity.
• Easily brazed in reducing atmospheres. Any oxygen present in copper will react with hydrogen during brazing to form steam which expands and may result in cracking. This is called steam (hydrogen) embrittlement. This is avoided in OFHC copper.
