OFHC Copper Rod
OFHC copper stands for Oxygen-Free High Conductivity copper. It is a type of copper that has been refined to remove oxygen and other impurities, resulting in a high-purity copper material with excellent electrical conductivity.
OFHC copper is commonly used in applications where high electrical conductivity is required, such as in electrical wiring, power transmission, electronics, and various other industries.
OFHC copper rods are cylindrical bars made of this high-purity copper. They are typically manufactured through a process called continuous casting, where molten copper is poured into a mold and solidified to form a continuous rod shape. The resulting OFHC copper rods have a smooth surface, uniform structure, and high electrical conductivity.
| Attribute | Description |
|---|---|
| Purity | OFHC copper is a high-purity copper material with minimal impurities, typically exceeding 99.95% copper content. |
| Conductivity | OFHC copper offers excellent electrical conductivity, with a conductivity rating of approximately 101% IACS (International Annealed Copper Standard). It is one of the most conductive commercial copper alloys. |
| Oxygen Content | OFHC copper is refined to have very low oxygen content, typically less than 10 parts per million (ppm). The absence of oxygen minimizes the formation of oxide layers, ensuring high electrical conductivity. |
| Thermal Conductivity | OFHC copper exhibits good thermal conductivity, making it an efficient material for heat transfer and dissipation. It has a thermal conductivity of approximately 400 W/m·K. |
| Tensile Strength | OFHC copper rods have a relatively high tensile strength, typically ranging from 200 to 250 MPa (megapascals), ensuring their mechanical reliability. |
| Ductility | OFHC copper is highly ductile, allowing it to be easily formed and shaped into various configurations, such as wires, rods, and other components. It can undergo extensive deformation without losing its electrical or mechanical properties. |
| Corrosion Resistance | OFHC copper exhibits good resistance to corrosion in various environments, making it suitable for both indoor and outdoor applications. However, it may still undergo some degree of tarnishing or oxidation over time. |
| Fabrication | OFHC copper rods can be easily fabricated through processes such as cutting, machining, forging, and welding. They can be formed into different shapes and sizes to meet specific requirements. |
| Applications | OFHC copper rods are commonly used in electrical and electronic industries for manufacturing wires, cables, bus bars, connectors, and various components where high electrical conductivity and reliability are essential. They are also utilized in heat exchangers, plumbing systems, and other applications requiring excellent thermal conductivity and corrosion resistance. |
