So far as the storage method of copper materials is concerned， we should properly keep the copper products we buy， extend the service life of copper and ensure its performance to avoid unnecessary losses.
Red copper plate has ductility. Pure copper， can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive ， second onlyver in common metals. But copper is much cheaper than silver， so it has become the "protagonist" of the electrical industry.
다 바스As the inner wall of the pipe rubs with water， its film is damaged， the greater the flow， and the more serious the corrosion.
Although the opening continued the weak trend， the intraday transactions improved， and the prices of some copper bar manufacturers rose. From the specific situation， although the manufacturer feedback that the shipment is average， the mentality is relatively calm， the market inventory is not much， and the manufacturer is not willing to significantly reduce the price. In terms of the market， the transaction of strip steel is better than other steel varieties， and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake， the overall demand for strip steel remains in a good state.

The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price， the cost of ductile iron in Shanxi， Henan， Liaoning， Shandong and other regions has increased. In addition， with the gradual release of downstream demand the inventory of iron plants is not large， and iron plants have successively raised their prices. There are few iron foundries in Shandong， Jiangsu，다 바스동봉， Hebei and Shanxi， and the inventory remains low. As the coke price rises and the cost increases， the price of iron foundries rises again.
The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm，다 바스304 스테인리스 파이프， the same below) yuan， yuan for Jin Zhengyang yuan， yuan for Ruigang Lianlian， yuan for Baoda yuan， yuan for Meixin yuan， and yuan for Taizong yuan.
Regularly inspect and monitor the copper pipe to reduce the loss caused by copper pipe corrosion.
Later，다 바스공심 알루미늄 관， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future， copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper， sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s， so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T， T， T， oxygen free copper plate (TU， TU and high-purity， vacuum oxygen free copper)， deoxidized copper plate (TUP， tellurium copper， silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere， sea water， some non oxidizing acids， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition， the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s， the output value of copper plate exceeded that of other copper alloys.
품질 개선Tangshan billets rose sharply last weekend， steel mills in some northern cities implemented production restriction， and some domestic economic data improved， which boosted manufacturers confidence. Today， steel prices generally rose. However， with the approaching meeting and the rainfall in the south caused by the typhoon， the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow， and some businesses may reduce prices and take goods.
The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.
antages: low production cost and high production efficiency.
Because of the characteristics of copper itself it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it， the problem will be smaller but if it is placed for a long time， it will cause acid corrosion to the copper wall.
상술한 바를 종합하면 the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.

다 바스To sum up， the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment， as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year， and it is hard to improve in the short and medium term. On the whole， the market price of Shenyang copper bars may be stable tomorrow.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
