Red Copper Application And Characteristics

Purple copper, also known as red copper, is copper elemental, because of its color for purple red named. See entry “copper”for various properties. Red copper is industrial pure copper, its melting point is 1083℃, No allotropic transformation, relative density is 8.9, which is five times that of magnesium. The mass of the same volume is about 15% heavier than ordinary steel.

Copper because of its rose red, the surface of the formation of oxide film is purple, so generally called red copper. 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 applicable in excellent thermal conductivity, ductility and corrosion resistance. Trace impurities in red copper have serious influence on the electrical conductivity and thermal conductivity of copper. Among them, titanium, phosphorus, iron and silicon significantly reduce the electrical conductivity, while cadmium and zinc have little effect. The solid solubility of sulfur, selenium and tellurium in copper is very small, and they can form brittle compounds with copper, which have little effect on electrical conductivity, but can reduce machining 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, can be processed into a variety of semi-finished products and finished products by cold and thermoplastic processing. In the 1970s, the production of red copper is surpass the total production of all other copper alloys.

Red Copper Parts Physical Properties

The trace impurities in red copper have serious impact on the electrical conductivity and thermal conductivity of copper.  Among them, titanium, phosphorus, iron and silicon significantly reduce the electrical conductivity, while cadmium and zinc have little effect. The solid solubility of sulfur, selenium and tellurium in copper is very small, and they can form brittle compounds with copper, which have little effect on electrical conductivity, but can reduce machining plasticity. When ordinary red copper is heated in a reducing atmosphere containing hydrogen or carbon monoxide, hydrogen or carbon monoxide can easily interact with cuprous oxide (Cu2O) at the grain boundary to produce high-pressure water vapor or carbon dioxide gas, which can crack the copper. This phenomenon is often referred to as the “hydrogen disease” of copper. Oxygen is harmful to the weldability of red copper. Bismuth or lead and copper form eutectic with low melting point, which makes copper brittle. The brittle bismuth distributed along grain boundaries as a thin film made copper brittle; When the brittle bismuth is distributed in the grain boundary in the form of a thin film, it makes the copper cold and brittle. Phosphorus can significantly reduce the electrical conductivity of red copper, but improve the fluidity of red copper liquid and improve weldability. Proper amount of lead, tellurium and sulfur can improve machinability. The room temperature tensile strength of the annealed copper sheet is 22-25 kgf/mm2, the elongation is 45-50%, and the Brinell hardness (HB) is 35-45.

The thermal conductivity of pure copper is 386.4 w/(m.k).

The use of red copper is much more extensive than pure iron, 50% copper is purified for pure copper by electrolysis every year, used in electrical industry. The red copper mentioned here really needs to be very pure, with a copper content of more than 99.95%. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Red copper is mainly used for the production of generators, busbars, cables, switching devices, transformers and other electrical equipment and heat conduction equipment such as heat exchanger, pipe, solar heating device flat collector. Oxygen in copper (a small amount of oxygen is easily mixed during copper smelting) has a great impact on conductivity. Copper used in the electrical industry must generally be oxygen-free copper. In addition, lead, antimony, bismuth and other impurities will make the crystallization of copper can not be combined together, resulting in hot brittle, will also affect the processing of pure copper. For this kind of high purity copper, generally finishing by electrolysis: Impurity copper (i.e. blister copper) was used as anode, pure copper as cathode and copper sulfate solution as electrolyte. When the current passes through, the impurity copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. The resulting copper is 99.99% pure.

Red copper is also used in the production of motor short-circuit rings, electromagnetic heating sensors, and high-power electronic components, wiring bar wiring terminals and so on.

Red copper is also applied ot door, window, handle and other furniture and decoration.
