Webb(sometimes referred to as OFHC-oxygen free high conductivity).Values are given with respect to RRR the (Residual Resistivity Ratio) which correlates the thermalresistivity and electrical resistivity as the impurity effect and is primarily additive in resistivity. Higher RRR values indicate higher purity and lower electrical and WebbThe yield ratio (yield strength / tensile strength) of Cu-0.3Cr-0.1Zr, however, was higher than that of OFHC Cu at lower temperature as shown in Figure 5, since both precipitation strengthen and dislocation strengthen may introduce high yield strength with less temperature dependence.

Oxygen-free high thermal conductivity (OFHC) copper is widely used in cryogenics. OFHC is produced by the direct conversion of selected refined cathodes and castings under carefully controlled conditions to prevent contamination of the pure oxygen-free metal during processing. Visa mer Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below. Visa mer Oxygen-free copper is typically specified according to the ASTM/UNS database. The UNS database includes many different … Visa mer For industrial applications, oxygen-free copper is valued more for its chemical purity than its electrical conductivity. OF/OFE-grade copper is used in plasma deposition (sputtering) processes, including the manufacture of semiconductors Visa mer High-electrical-conductivity coppers are distinct from coppers deoxidized by the addition of phosphorus in the smelting process. Oxygen-free phosphorus-containing copper (CuOFP) is typically used for structural and thermal applications where … Visa mer Conductivity is generally specified relative to the 1913 International Annealed Copper Standard of 5.8×10 S/m. Advances in the refining process … Visa mer The high-end speaker wire industry markets oxygen-free copper as having enhanced conductivity or other electrical properties that are supposedly advantageous to audio signal transmission. … Visa mer • Copper wire and cable Visa mer WebbTable A3.

Oxygen-Free High-Conductivity Copper - an overview
WebbCharacteristics of OFHC copper are: High Ductility High Electrical & Thermal Conductivity High Impact Strength Good Creep Resistance Ease of Welding Low Relative Volatility under high vacuum C10100 TYPICAL USES Transistor Component Bases, High Resistance-Ratio Cryogenic Shunts, Bus Conductors, Wave Guides, Hollow Conductors, Webb10 maj 2016 · Modern techniques of severe plastic deformation (SPD) used as a means for grain refinement in metallic materials rely on simple shear as the main deformation mode. Prediction of the mechanical properties of the processed materials under tensile loading is a formidable task as commonly no universal, strain path independent constitutive laws … WebbWhen deformed at these high strain rates, the OFHC copper exhibits an increase in the yield strength, the strain-hardening rate and the ultimate dynamic strength relative to their conventional quasi-static values. The OFHC copper results are then compared with high strain rate measurements for high purity 1100 aluminum. thurlow fisher lawyers
