손님 을 모시다.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，약속 하 다.황동판， the overall demand for strip steel remains in a good state.

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.
Red copper bars in other regions basically follow the price trend of Tangshan， in which the bid of Jiangsu Steel Works tends to be higher， and most of the downstream prices are asked， and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary， and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak， so they hold a cautious wait-and-see attitude. At prepresent， the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.

Among the three production methods of copper tube copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material 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.

높 은 가치In Jiangyin market， another distribution center， the overall inventory of the current circulation link is about tons， slightly lower than the normal level. At the beginning of this week， the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However， from the perspective of the policy port of the steel plant， the overall production situation of Nangang， Hengrun， etc. is relatively normal， and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons，약속 하 다.310s 스테인리스 파이프， which is a medium normal level， and the recent spot price of Lecong market has a large gap with that of the north.

Disadvantages of copper pipe As far as copper pipe is concerned， high production cost and high price are its biggest disadvantages. Compared with other pipe fittings， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level.
