Alpha Nickel

Cupro Nickel Flanges Manufacturer, Supplier In Mumbai India

Alpha Overseas is famous in the market for its Copper Nickel flanges. Due to its outstanding resistance to corrosion caused by seawater, copper-nickel is frequently utilized in maritime applications, also known as cupronickel alloys. A form of a copper alloy called cupronickel, often known as copper-nickel (CuNi), contains nickel and fortifying elements like iron and manganese.

Flanges made of copper-nickel alloy exhibit corrosion resistance on par with copper, increased overall strength, and improved fatigue strength. Copper Nickel Alloy Pipe Flanges offer higher dependability and guarantee improved longevity for vehicle manufacturers and owners. Cu-Ni flanges' simple process of alloying with other materials and metals has significantly benefited our modern society and ensured that we can continue providing the necessary materials for a more challenging future. These Cupronickel Flanges, which are extensively alloyed with aluminum, chromium, or tin, are utilized in applications that call for increased resistance to the passage of seawater, sand abrasion, wear, and galling, as well as higher mechanical qualities.

Cu-Ni Alloy Flanges are also utilized for thermocouples because it produces a strong and consistent EMF when combined with other metals like copper and iron. Although the metal price is higher than steel equivalents, good formability makes it easy to flare and bend. Cupronickel Alloy Flanges are particularly appealing due to their extended lifespan, trouble-free installation, and safety/reliability features.

The Cupro Nickel 90/10 Slip On Flanges UNS C70600 maintains a high degree of strength at relatively high temperatures. For Cupro Nickel 90/10 Threaded Flanges, typical applications include valves, pump components, fittings, flanges, and other nautical equipment. Cupro Nickel 90/10 Weld Neck Flanges have many advantages that designers and specifiers can use, such as their superior fabrication and welding capabilities, high resistance to hydrogen embrittlement, retention of mechanical properties down to cryogenic temperatures, and excellent resistance to stress corrosion, erosion, and biofouling in seawater and saltish water.
