Chemical Composition

Cu-OF, short for Copper Oxygen-Free, is a type of high-purity copper alloy that has an extremely low oxygen and impurities content. The chemical composition of Cu-OF typically includes 99.99% copper and trace amounts of other elements such as Iron, Phosphorus, and Nickel. Due to its high purity, Cu-OF has exceptional electrical and thermal conductivity and corrosion resistance properties.

One of the key characteristics of Cu-OF is its high purity level. The low oxygen content in Cu-OF reduces the chances of oxidation and the formation of corrosion, making it an ideal choice for use in harsh environments, such as industrial settings, and in marine applications.

The high thermal conductivity of Cu-OF is also a valuable characteristic. It effectively dissipates heat and prevents equipment from overheating, making it an ideal choice for use in electronic devices, electrical equipment and scientific instruments.

Cu-OF also has high electrical conductivity, making it an excellent choice for use in electrical wiring, as it can transmit electricity with minimal resistance.

In conclusion, Cu-OF is a high-purity copper alloy that is known for its exceptional electrical and thermal conductivity and corrosion resistance. Its low oxygen and impurities content makes it an ideal choice for electronic, electrical and scientific applications. The chemical composition of Cu-OF typically includes 99.99% copper and trace amounts of other elements such as Iron, Phosphorus, and Nickel.

Equivalents

Cu-OF (Oxygen Free Copper) is a high-purity copper with a minimum of 99.99% copper content. Other materials that can be used as a substitute for Cu-OF include:

• C10100, C10200, C10300, C10800, C12000: These are all high conductivity copper alloys with varying levels of purity and properties.

• ETP Copper: Electrolytic Tough Pitch Copper is a commonly used copper alloy that has a similar conductivity and corrosion resistance to Cu-OF.
• Silver: Silver is a more expensive option but has a higher conductivity than Cu-OF.

• Aluminum: Aluminum is a lower-density, lower-cost alternative to Cu-OF that can be used in some electrical applications.

• Gold: Gold is another more expensive option but has a higher conductivity than Cu-OF.

It’s important to note that the final selection of a substitute material will depend on the specific application and the properties that are required.
