Silver tubes is one of the leading manufacturer, stockiest & trader of high quality Cu-Ni 70 / 30 Flanges, where the silicon improves the castability of casting alloys and at the same time acts as deoxidant. Since Cu-Ni 70 / 30 Pipe Flanges have strong antimicrobial properties, they are marketed as hygienic touch materials to reduce cross-contamination and infections, particularly in hospital intensive care units. Nickel has a significant effect on the physical and mechanical properties of Copper Nickel 70 / 30 Flanges. Tensile strength increases with nickel content in Cupro Nickel 70 / 30 Flanges, where elongation remains almost constant after a slight decrease. Copper Nickel 70 / 30 Pipe Flanges has excellent tensile strength, proof strength, hot strength, solidus and liquidus temperature and corrosion resistance increase with nickel content, thermal and electrical conductivity decrease.
Cupro Nickel 70 / 30 Pipe Flanges are distinguished by very good resistance to stress relaxation and therefore are used a spring materials. Alloy 70 / 30 Flanges with even higher tin contents (4 % to 10 %) can also be age-hardened. In Alloy 70 / 30 Pipe Flanges, the solubility of silicon increases with nickel content. The cast alloys with high lead contents in UNS C71500 Flanges, are well-known and are used for machining. Alloy C71500 Flanges is used for making electronic components, nuclear reactors, chemical equipment, semiconductors, heat exchangers and for radiation shielding. Silver tubes also offer these flanges at best possible rates to their customers.
