COPPER NICKEL COUPLINGS
Copper-Nickel Couplings by Nexus Alloys and Steels, also known as CuNi Couplings, are a category of forged fittings that are extensively used in various industrial applications. These Couplings are manufactured from a special alloy that combines copper and nickel, providing them with exceptional resistance to corrosion, making them particularly suitable for use in marine environments. The process of forging involves heating the copper-nickel alloy until it reaches a malleable state, and then it is shaped under high pressure. This process ensures that the Couplings are highly durable and can withstand extreme pressures and temperatures
DESCRIPTION
These Couplings from Nexus Alloys and Steels find their application in a wide range of industries such as shipbuilding, desalination plants, and offshore oil and gas platforms, where they are exposed to harsh conditions. They are available in a variety of sizes and configurations, making them adaptable to different piping requirements. In essence, Copper-Nickel Couplings from Nexus Alloys and Steels are a robust and reliable solution for demanding industrial applications, offering a unique combination of durability, corrosion resistance, and adaptability. Their superior performance in challenging conditions makes them an ideal choice for industries looking for long-lasting and efficient piping solutions

GRADES
- UNS C70600 : Copper Nickel 90/10 (Cu-Ni 90/10), also recognized as UNS C70600, consists of 90% copper and 10% nickel. This alloy showcases outstanding corrosion resistance, particularly in marine environments. Small amounts of iron and manganese further augment its overall strength and corrosion resistance. With favorable machinability and a suitable melting point, it finds applications across various industries
- UNS C71500 : Copper Nickel 70/30 (Cu-Ni 70/30), identified as UNS C71500, features a composition of 70% copper and 30% nickel. With a higher nickel content compared to Cu-Ni 90/10, it offers superior resistance to corrosion and erosion. The alloy, enriched with minor quantities of manganese and iron, exhibits heightened resistance to both erosion and corrosion. Its impressive mechanical properties include an ultimate tensile strength of 310 N/mm², an elongation of 27%, and a hardness ranging from 80 to 120
