The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
Advantages and scope of application of copper tube ground heating At present， ground heating is not only a comfortable heating method， but also a symbol of modern life quality. More and more houses， public buildings， sports facilities， industrial facilities and other places begin to use ground heating radiator， which is an important part of ground heating. Due to the corrosion resistance of copper， copper tubes are selected as the main material of radiator in many places.

Red copper plate has ductility. Pure copper， which is as big as a drop of water， 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.

The excellent performance of copper pipe The copper pipe has the characteristics of and， which makes it a suitable choice for modern contractors to install water pipes，피 터 레 티 브합금강， heating and cooling pipes in all residential commercial housing.
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.
Under the action of high welding temperature，피 터 레 티 브6063 알루미늄 튜브， the evaporation amount of zinc is as high as % during shielded metal arc welding. A large amount of zinc evaporation leads to the decline of mechanical properties and corrosion resistance of welded joints， and also increases the sensitivity to stress corrosion.

품질 관리수분 분리기는 재료가 같고 팽창 계수가 같아 수분 분리기와의 연결이 잘 새지 않는다.적용 범위: 구리 파이프가 플라스틱 파이프보다 비싸기 때문에 난방 시스템의 비용이 더 높습니다.
The market opened today. Although the performance of Zitong Pai futures was modest the overall market has stopped. The market mentality has not changed much sincekend. The price is stable， but some specifications are subject to negotiation， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.

Copper is light.
Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe， characterized by light weight， good thermal conductivity， high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes， the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?
피 터 레 티 브The 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， 최근 창저우의 빈틈없는 강관 시장 가격은 안정 속에서 약해질 것으로 예상된다.
