Copper Nickel 90 / 10 Fasteners Manufacturer

Astec Tubes is a leading manufacturer and exporter of Cu-Ni 90/10 Fasteners that are being designed as per the national and international standard quality. Copper Nickel Fasteners are manufactured using an ideal mixture of Copper 90 percent and nickel 10 percent with additions of manganese and ferrous contents like iron. These Cupro Nickel C70600 Fasteners are available in various types such as Bolts, Nuts, Screws, Studs, and Washers. Copper Nickel 90 / 10 Fasteners have good fabricability and high inherent resistance to bio fouling. The addition of manganese, niobium, iron and or chromium in these alloys improves their corrosion resistance and strength. The alloy provides good ductility and toughness at high temperatures. In addition to these characteristics, there is superior resistance to corrosion, stress corrosion and erosion. These are also highly resistant to hydrogen embrittlement and offer excellent mechanical properties down to cryogenic temperatures. The fasteners maintain strong thermal stability and moderate strength at high temperatures.

The 90/10 Fasteners are widely used as they are inexpensive and have great resistance to sea water corrosion. Cupro Nickel 90 / 10 Fasteners are used in the following applications such as hydraulic lines, fish cages for aquaculture, heat exchangers and condensers, desalination units, sea water pipework, power plants and ships, offshore fire water systems, pumps, valves, sheathing for ship hulls, etc. UNS C70600 copper nickel alloys are annealed at temperatures between 593 degrees and 816 degrees C (1100 degrees and 1500 degrees F). UNS C70600 Cupro Nickel Fasteners are used in areas where stainless steel cannot be used due to chloride stress-corrosion cracking and in other parts requiring high levels of corrosion resistance.
