Oxygen-free copper is pure copper without oxygen or any deoxidizer residue. But it actually contains a very small amount of oxygen and some impurities.
Red copper, also known as red copper, is a simple substance of copper, named after its purple color. See the various characteristics of copper.
2. Different characteristics
According to the oxygen content and impurity content, oxygen-free copper can be divided into 1 and No.2 oxygen-free copper. The purity of 1 oxygen-free copper reaches 99.97%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.03%. The purity of No.2 oxygen-free copper reaches 99.95%, the oxygen content is not more than 0.005%, and the total impurity content is not more than 0.05%.
Red copper is industrial pure copper with melting point 1083℃ and relative density of 8.9, which is five times that of magnesium. The mass of the same volume is about 15% heavier than that of ordinary steel.
3. Different applications
Oxygen-free copper products are mainly used in electronic industry. It is often made into copper materials such as oxygen-free copper plate, oxygen-free copper strip and oxygen-free copper wire.
The conductivity and thermal conductivity of red copper are second only to that of silver, and it is widely used to make electrical and thermal conductivity equipment. Copper has good corrosion resistance in atmosphere, seawater, some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid), and is used in chemical industry.
