Oxygen-free copper (OFC) is an alloy composed of 99.95% to 99.99% pure copper with trace amounts of oxygen. This gives it superior electrical and thermal conductivity properties compared to other types of copper alloys. This makes OFC the preferred material for a wide range of applications, such as instrumentation wiring, signal transmission, and power distribution, in critical settings where uninterrupted performance is essential.
It is also renowned for its excellent durability, making it ideal for connecting heavy-duty wires that need to resist wear and tear. Additionally, Oxygen-Free Copper Rods can be bent without losing shape or compromising reliability.
The high purity improves structural integrity while providing enhanced electrical conductivity across long distances, making OFC rods the ideal choice for many electronic and industrial applications.
At Max Steels, our Oxygen-Free Copper Rods are available in various sizes, from 0.5mm to 25mm in diameter, ensuring you have the right rod for your project. Our products also come with an industry-standard certification of conformance for quality assurance. With top-rated performance and reliability, our Oxygen-Free Copper Rods are perfect for any application requiring high accuracy and efficiency.
You must go to Max Steels' online site and order oxygen-free copper rods for industrial use.

ASTM B187 / SB187 - Standard Specification for Copper, Bus Bar, Rod, and Shapes and General Purpose Rod, Bar, and Shapes.
DIN 2.0040 - Oxygen free (OF), pure Copper processed without desoxydation additions. The electrical conductivity at 20°C is 101% IACS. Excellent resistance to environmental atmosphere, sea water and non-oxidizing acids. Poor resistance, however, to oxidizing acids and vapors containing sulfur, halogen or ammoniac.
C10100 - Oxygen-Free Electronic Copper, also known as OFE, is a 99.99% pure copper with 0.0005% oxygen content. C101 achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment..
C10200 - High Conductivity (OFHC) Copper characteristics are high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of welding, and low volatility under high vacuum.

| (1) This is a high conductivity copper which has, in tde
annealed condition a minimum conductivity of 100% IACS except for Alloy
C10100 which has a minimum conductivity of 101% IACS. (2) Cu is determined by tde difference between tde impurity total and 100 %. For alloy C10100 tde Cu value is exclusive of Ag. (3) The following additional impurity maximum limits shall apply: Bi 1ppm (0.0001%); Cd 1ppm (0.0001%); Mn 0.5ppm (0.00005%); Ni 10ppm (0.0010%); Se 3ppm (0.0003%); S 15ppm (0.0015%); Sn 2ppm (0.0002). |
