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.So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy,Xiao Benzhen310s stainless steel seamless pipe, extend the service life of copper and ensure its performance to avoid unnecessary losses.Xiao Benzhen,When heating steel pipes, the temperature is slightly higher than when heating copper pipes.I don t know how to keep the copper tube.Goitapa,Copper tube is a kind of nonferrous metal tube, which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity, and is solid and corrosion resistant. It will not crack when compared with the ambient temperature, so it becomes the first choice for modern contractors to install the water pipe, heat supply pipe and refrigeration pipe in all residential commercial houses.In the first ten days of May, the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data, the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock, the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons while at the end of April, the total quantity of post settlement agreements of main steel plants can exceed tons.On November , the market price of Cangzhou copper bar was stable. According to the monitoring data of Lange Iron and Steel s cloud business platform, the market price of * mm cold drawn steel produced in Linyi is yuan, the market price of * mm in Linyi is yuan,Xiao Benzhen5083 aluminum bar, the market price of * mm in Jianlong is yuan, the market price of * mm in Yuanhua is yuan, the market price of * mm in Juneng is yuan, the market price of * mm in Baotou Steel is yuan, and the market price of * mm in Juneng thermal expansion is yuan.

In 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, the overall production situation of Nangang, Hengrun, Dada 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, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.If the environment is wet, it will aggravate the corrosion of copper pipes. Oxygen in water causes corrosion.Disadvantages: low output, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.Administration,Xiao Benzhen15CRMO alloy plate,Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.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, which led to the price being s table for the next two days. Until Wednesday, 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 off-season is coming, 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.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm the elongation is ~%, and the Brinell hardness (HB) is ~

It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.How much is it,In 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, the overall production situation of Nangang, Hengrun, Dada, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.The water quality at the place where the copper pipe is required to be installed shall be studied, and the appropriate water quality and water flow shall be selected for pipe distribution to prevent the root cause.Save materials and total cost, stability and performance and can save maintenance.Xiao Benzhen,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, 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, 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.Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.Today, the price of tube billets is up and down. At present, continuous casting yuan is down yuan, Dongfang hot rolling yuan is down yuan, Luli hot rolling yuan is down yuan, Tiangang hot rolling an is down yuan, production is stopped in mid January, Weigang hot rolling yuan is up yuan, continuous casting yuan is up yuan Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan, Linggang yuan.
