t2 copper rods

t2 copper rods as the name suggests is one of a family of copper species, t2 copper rods of material introduced

Material Name: t2 copper rods criteria: (GB / T5231-2001) Features and Scope: There is a good thermal conductivity and corrosion resistance processing performance, welding and brazing.. Containing reduce the conductivity. Less thermal impurity, a trace amount of oxygen has little effect on the conductivity. Thermal and processing properties, but can lead to "hydrogen disease", not processing (annealing at a high temperature (e.g.> 370 °) in a reducing atmosphere, welding, etc.) and use.

t2 elemental copper is copper rods, named for its color is purple. See various properties of copper. Copper is the copper industry, its melting point is 1083 ℃, no allotrope changes relative density of 8.9, five times as magnesium. Also weighs about 15% than ordinary steel. It has red roses, the oxide film formed on the surface purple, it is generally known as copper. It is a copper-containing oxygen, which is also called an oxygen-containing copper.

Nature 1.t2 copper rods

Copper because purple is named. It is not necessarily a pure copper, and sometimes a small amount of deoxy elements or other elements to improve the performance of the material and therefore classified as a copper alloy. Chinese copper processing material components can be divided into: ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high-purity, oxygen-free vacuum), deoxidized copper (TUP, TUMn), add a small amount of alloy special copper elements (arsenic copper, tellurium copper, silver and copper) four. Copper electrical and thermal conductivity second only to silver, widely used in the production of electrical conductivity, thermal equipment. Copper in the atmosphere, water and certain non-oxidizing acid (hydrochloric acid, sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid), there are good corrosion resistance, for the chemical industry. In addition, copper has good weldability, may be cold, processed into a variety of thermoplastic semi-finished and finished products. 1970s, copper production exceeded the total production of other types of copper alloys.

t2 copper rods trace impurities have a serious impact on the electrical conductivity, thermal conductivity of copper. Wherein a significant reduction of titanium, phosphorus, iron, silicon and other electrical conductivity, and cadmium, zinc, etc. are little effect. Oxygen, sulfur, selenium and tellurium in the solubility of copper is very small, and the copper compound may be generated brittle, have little effect on the conductivity, but can reduce the processing of plastic. Heating at ordinary copper hydrogen or carbon monoxide in the reducing atmosphere of hydrogen or carbon monoxide easy and cuprous oxide grain boundaries (Cu2O), thus producing a high pressure steam or carbon dioxide gas, the copper can rupture. This phenomenon is often referred to as copper "hydrogen disease." With excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. Mainly used for thermal flat plate collectors and other equipment produced generators, bus, cable, switch gear, transformers and other electrical equipment and heat exchangers, piping, solar heating device. Commonly used copper alloys brass, bronze, copper-nickel alloy is divided into three categories.

Pure copper is purple metal, commonly known as "copper", "copper" or "Akagane." Copper rich ductility. Like a drop of water so the size of the copper, can grow up to two kilometers pull filaments, or rolled into a bed bigger than almost transparent foil. Copper is the most valuable properties of the conductive performance is very good, second only to silver in all of metal. But silver is much cheaper than copper, thus became the electrical industry "hero."

2.t2 uses copper rods

The use of copper is much more extensive than pure iron, each year 50% of the copper electrolysis purification of copper, used in the electrical industry. Here, the copper is indeed to be very pure, more than 99.95% copper job. Very small amounts of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Copper in oxygenated (oxygen easily when mixed with a small amount of copper) on the conductivity of the large copper is generally used in the electrical industry must be oxygen-free copper. In addition, lead, antimony, bismuth crystals of copper and other impurities will not be combined together, resulting in hot crisp, also affect copper processing.

t2 is relatively pure copper rod as a copper, copper is generally considered to be approximated, a conductive plastic are good, but the strength, hardness, some poor.
