 1 Overview of the national standard T1 copper row 
 Copper was a row of purple due to its name. It may not be pure copper, and sometimes a small amount of oxygen elements or other elements to improve the material and performance 
 And, therefore, classified as copper alloy. Chinese copper processing row materials according to composition can be divided into: ordinary copper row (T1, T2, T3, T4), oxygen-free copper (TU1, TU2, and high-purity, oxygen-free copper vacuum 

 ), Deoxidized copper (TUP, TUMn), add a small amount of special alloying elements copper (copper, arsenic, tellurium copper, silver and bronze) four. Copper row after electrical and thermal conductivity of silver, a wide range 

 For the production of electrical conductivity, thermal equipment. Copper came in the atmosphere, water and certain non-oxidizing acids (hydrochloric acid, sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid 

 ) Has a good corrosion resistance, for the chemical industry. T1 copper is ranked as the highest copper content of copper, the purity up to 99.95%, also the most expensive. Net commonly used in industry 

 T2 copper copper row, and affordable.

 Industrial metal copper, purity higher than 99.5%, was purple, also known as pure copper. It has excellent electrical conductivity, thermal conductivity, corrosion resistance and weldability, the conductivity at room temperature, second only to 

 In silver. Processing of copper row, which was divided into four kinds of grades, that I, II, III and IV copper row, purity of 99.95%, 99.90%, 99.70% and 99.5%; that 

 The so-called T1, T2, T3, T4. 

 3 GB T1 copper discharge characteristics 
 Good electrical conductivity, thermal conductivity, corrosion resistance and workability, welding and brazing. With lower conductivity, thermal conductivity less impurities, small amounts of oxygen on the electrical conductivity, thermal and processing properties of film 

 Sound small, but easy to cause the "hydrogen disease", not at high temperature (eg> 370 ℃) reducing atmosphere processing (annealing, welding, etc.) and use. Often contain oxygen, sulfur, lead, arsenic, bismuth 

 , Phosphorus and other impurities. Has excellent electrical conductivity, thermal conductivity, moderate mechanical properties. Can be used for the preparation of copper alloy and alloy elements. Electric fields are widely used for electrical conductivity, 

 Thermal conductivity materials. With the reverberatory furnace and other pyrometallurgical copper, refined copper electrolysis. Preparation or sources: natural copper are important chalcopyrite, chalcocite, cuprite and malachite, 

 However, all low grade. Sulfide ores can be calcined to a small amount of sulfur dioxide and coke after crude copper eutectic, and then reduced to blister copper, and finally refining electrolysis derived. Copper row 

 Trace impurities on the conductivity of copper, thermal conductivity have a significant effect. Including titanium, phosphorus, iron, silicon significantly lower conductivity, and cadmium, and zinc is little effect. Oxygen, sulfur, selenium 

 , Tellurium, etc. in the solid solubility of copper in small, brittle compounds can be generated with copper, has little effect on the conductivity, but can reduce the processing of plastic. Ordinary copper came in hydrogen or carbon monoxide also 

 Immunogenicity when heated in an atmosphere of hydrogen or carbon monoxide is easy and cuprous oxide grain boundaries (Cu2O) effect, resulting in high pressure steam or carbon dioxide gas, copper can break. This phenomenon is often 

 Called copper "hydrogen disease." Oxygen on the copper welding and harmful. Bismuth or lead and copper to generate low melting point eutectic, thermal embrittlement of copper; and brittle thin film of bismuth was distributed at the grain boundaries, and 

 Of copper produced cold crisp. Phosphorus can significantly reduce the conductivity of copper, but copper can increase the fluid flow, improve weldability. Amount of lead, tellurium, sulfur, etc. can improve machinability.

 Pink and shiny metal, hard and tough, the rich have a high ductility and thermal conductivity and electrical conductivity. 
 Solution: do not dissolve in hydrochloric acid or sulfuric acid. Soluble in hot concentrated nitric acid and sulfuric acid. Alkali corrosion. 
 Purposes: for copper, copper, electrodes, electro-forming panels, switches, chemicals, alloys (eg brass, bronze, German copper, copper-nickel alloy, etc.), and electroplating. With excellent 

 Good thermal conductivity of the conductive ﹑ ﹑ ductility and corrosion resistance. Mainly for the production of the generator bus ﹑ cable ﹑ ﹑ ﹑ transformer electrical switchgear equipment and heat exchanger pipes ﹑ ﹑ 

 Solar heating devices such as flat-plate collector thermal equipment. Commonly used copper alloy into copper-nickel alloy brass ﹑ ﹑ bronze three categories.
