It is mainly used to manufacture electrical devices such as generators, buses, cables, switchgear, transformers, and thermal conductive devices such as flat plate collectors for heat exchangers, pipes, and solar heating equipment. Common copper alloys are divided into three categories: brass, bronze and white copper. Pure copper plate is a purplish red metal, commonly known as & quot; copper plate& quot;, & amp; quot; red copper plate& quot; or & quot; red copper plate& quot;.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.Hula,This week (-, the market price of red copper bar rose, and the transaction was not ideal. On the bidding day of Shagang last weekend, the price was stable to support the market, and the rising of billets at the weekend drove the market up in a wave, and the price of variety wire rods also rose by yuan at the weekend. However it was reported that the deal was very poor, due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving, the market lowered the price. Market price changes, Xinji rose yuan on the rd; For the future market, the demand is weakening, and the market wait-and-see mood is getting stronger. But when winter comes, the environmental protection inspection is becoming more and more strict, which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.In view of the current overall price difference, the local copper bar price continued to rise at a high level today, while the regions outside East China did not show an obvious follow-up trend, and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction, and the price support of copper bar is still strong. However, at present, domestic real estate control is still being tightened. The market s expectation of future demand is weakening, the market price of copper bars in Shenyang is stable and the shipment is poor.However, it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits, Tangshan Iron and Steel Group Co., Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits, or to lay hidden dangers for the decline. As far as tomorrow is concerned, the price may still maintain a narrow range of shock operation pattern.

Insert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint, and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux and the joint is assembled and can be heated.Standardized design.The copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing recently, but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently, the steel market has been in shock and adjustment, and the merchants are unstable. Steel mills in Hebei, Tianjin and other regions have stopped producing pig iron for steelmaking. Now, it is mainly expected to make inquiries. However, due to the lower price of raw materials the price of iron mills has been lowered.Administration,If you want to avoid this kind of situation for a long time, you can choose passivation treatment. In this way, not only is the copper surface serious, it can be cleaned under normal circumstances, but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment, so this effect is very good.The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special, and copper ions can be separated by conductivity, so that copper tubes can be produced with the separated copper ions. This method is very complex, requires high technology and new equipment, so only advanced foreign countries can use this production method.Advantages: good quality, fine structure, high density, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange, and large size copper tube can be produced.

Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing recently but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently,HulaAluminum bronze plate, the steel market has been in shock and adjustment, and the merchants are unstable. Steel mills in Hebei, Tianjin and other regions have stopped producing pig iron for steelmaking. Now it is mainly expected to make inquiries. However, due to the lower price of raw materials, the price of iron mills has been lowered.(Brass is a copper zinc alloy. Due to the low boiling point of zinc, which is only ℃, it is very easy to evaporate during welding, which becomes a problem in brass welding.Some steel mills in Liaoning are interested in purchasing pig iron but the local resources are tight, and the iron mills quotations are on the high side, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the quotation of iron mills continues to decline. At present,Hula2507 stainless steel plate, the demand and cost support are weak, and there is no positive boost. The short-term pig iron market is weak and difficult to change.Hula,In the middle and late ten days, although there were good news such as the rise of futures and the increase of production restriction policy in Wu an region, due to the high inventory level, traders had no desire to increase prices, most of them had shipped goods, and spot prices lacked motivation to rise. The market inventory rose significantly. At that time, the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market, and the continuous rise of inventory led to the empty market mentality.Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side, resulting in a stalemate between supply and demand.

The short-term pig iron market is weak and difficult to change.Among the three production methods of copper tube,HulaAlloy plate, the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material, the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time, but also has a mature technology, which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
