Copper

Copper is industrial pure copper. Because of its rose red color and purple color after the oxide film is formed on the surface, it is generally called red copper, also known as red copper. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper, and sometimes it can also be regarded as a copper alloy. It has good electrical and thermal conductivity, excellent plasticity, and is easy to be processed by hot pressing and cold pressing. It is widely used in the manufacture of wires, cables, brushes, electric corrosion copper for electric sparks and other products that require good electrical conductivity. Copper is generally divided into copper plates, copper tubes, copper coils, copper rods, copper wires, etc.

Product description

1. Copper plate has good mechanical properties, good plasticity in hot state, fair plasticity in cold state, good machinability, easy brazing and welding, and corrosion resistance. It is a common copper variety widely used.

2. Copper tube is a kind of non-ferrous metal tube. are pressed and drawn seamless tubes. Copper tubes are much more widely used than pure iron, and are generally used in the electrical industry

3. Copper rods are named for their purplish red color. They have good electrical and thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed. Generally used in the chemical industry

4. Copper wire, that is, linear copper (red copper). Pure copper is rose red, and the copper oxide film formed on the metal surface turns purple, so industrial pure copper is often called red copper or electrolytic copper. High-quality magnetic instruments and meters, excellent plasticity, easy to process by hot pressing and cold pressing

Classification

Copper processing materials can be divided into: ordinary copper (T1, T2, T3), oxygen-free copper (TU1, TU2 and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), special copper with a small amount of alloying elements Four types of copper (arsenic copper, tellurium copper, silver copper). The electrical conductivity and thermal conductivity of copper are second only to silver, and it has excellent thermal conductivity, ductility and corrosion resistance, and is widely used in the production of electrical and thermal equipment. Copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid).

Features: high purity, fine tissue, extremely low oxygen content. No porosity, trachoma, porosity, excellent electrical conductivity, high surface precision of the electroeroded mold, after heat treatment process, the electrode is non-directional, suitable for precision beating, fine beating, with good thermal conductivity, processability, ductility, Corrosion resistance and weather resistance, etc.

Application

Copper is much more widely used than pure iron. Every year, 50% of copper is electrolytically purified into pure copper for use in the electrical industry. It is mainly used in the production of electrical equipment such as generators, busbars, cables, switchgears, and transformers, and heat-conducting equipment such as heat exchangers, pipes, and flat collectors for solar heating devices. Oxygen in copper (a small amount of oxygen is easily mixed in copper smelting) has a great influence on conductivity, and the copper used in the electrical industry must generally be oxygen-free copper. Copper is also used in motor short-circuit rings, electromagnetic heating inductors, high-power electronic components, terminal blocks and the like. It is also applied to doors, windows, handrails and other furniture and decorations.

Product packaging

Generally, standard sea and land transportation packaging is adopted, with waterproof packaging with side protection , plastic straps, steel hoops and sealing rings, and wooden pallets at the bottom. Packaging and transportation can also be carried out according to customer requirements.
