Red Copper knowledge points

Red Copper also known as red copper, is a simple substance of copper. It is named for its purple-red color after an oxide film is formed on its surface. Red copper is industrial pure copper with a melting point of 1083°C, no allotropic transformation, and a relative density of 8.9, which is five times that of magnesium. The mass of the same volume is about 15% heavier than ordinary steel.

It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper.

Red copper is a relatively pure type of copper, which can generally be approximated as pure copper. It has good electrical conductivity and plasticity, but its strength and hardness are relatively poor.

Red copper has excellent thermal conductivity, ductility and corrosion resistance. The trace impurities in red copper have a serious impact on the electrical and thermal conductivity of copper. Among them, titanium, phosphorus, iron, silicon, etc. significantly reduce the conductivity, while cadmium, zinc, etc. have little effect. Sulfur, selenium, tellurium, etc. have very low solid solubility in copper, and can form brittle compounds with copper, which has little effect on electrical conductivity, but can reduce processing plasticity.

Red copper has good corrosion resistance in the atmosphere, sea water, certain non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid), and is used in the chemical industry. In addition, red copper has good weldability and can be processed into various semi-finished and finished products through cold and thermoplastic processing.
