C11000 Oxygen Free Copper is a high purity copper material with extremely low oxygen content, usually containing more than 99.9% copper. This material is used in a wide variety of applications due to its excellent electrical, thermal, corrosion and processing properties.



C11000 oxygen-free copper has a purplish-red color and a purple color after the formation of an oxide film on the surface, so it is also often referred to as purple copper. Its melting point is 1083, the relative density of 8.9, heavier than ordinary steel is about 15%. C11000 oxygen-free copper has good welding and brazing performance, and contains a reduction in electrical conductivity, thermal conductivity impurities are less, trace amounts of oxygen on the electrical conductivity, thermal conductivity and processing and other properties have little effect. However, it is processed at high temperatures (such as greater than 370) in a reducing atmosphere, easy to cause "hydrogen disease", so it is not suitable for processing and use in this environment.
C11000 oxygen-free copper is mainly used in the manufacture of electrical, thermal conductivity and corrosion-resistant components, such as wires and cables, conductive screws, shells and a variety of conduits. It also has a wide range of applications in the aerospace industry. In addition, C11000 Oxygen Free Copper has good thermoelectric channel, processability, ductility, weather resistance and other properties, which makes it outstanding in various fields.
