Nestled in the industrial heart of Safat, Kuwait, Nimish Metal has built a reputation for delivering exceptional quality and reliability. We specialize in the production and supply of high-performance Copper Nickel 7030 forgings, engineered to meet the most demanding industrial standards. Our commitment lies in providing robust solutions that stand up to harsh environments, ensuring our clients receive components that offer unparalleled durability and long-term performance. Trust Nimish Metal for forgings that are crafted with precision and a deep understanding of marine and industrial applications.
The strength of Copper Nickel 7030, or CuNi 70/30, lies in its specific composition and properties. This alloy is primarily composed of 70% copper and 30% nickel, with small additions of iron and manganese that significantly enhance its resistance to seawater corrosion. Mechanically, these forgings are incredibly tough; they offer excellent tensile strength and outstanding resistance to both corrosion fatigue and biofouling. This combination makes them exceptionally reliable under high stress and in aggressively corrosive settings, ensuring a long service life where other materials might fail.

The durability of Copper Nickel 70/30 forgings is ensured by excellent corrosion resistance, high tensile strength, superior weldability, resistance to seawater, anti-biofouling properties, and consistent alloy composition for enhanced performance.
Copper Nickel 70/30 forgings offer superior strength, enhanced corrosion resistance, improved material utilization, reduced waste, better grain structure, and higher durability compared to machining, making them ideal for demanding applications.
Compatible welding processes for Copper Nickel 70/30 forgings include TIG (GTAW), MIG (GMAW), and shielded metal arc welding (SMAW), ensuring strong joints, excellent corrosion resistance, and minimal thermal distortion.
The unique properties of these forgings make them indispensable in critical marine engineering. They are the preferred choice for essential components like seawater pump shafts, propeller shafts, and heavy-duty valve bodies on ships and offshore platforms. Beyond the sea, their reliability is trusted in desalination plants, power generation condensers, and chemical processing equipment. Essentially, wherever there is a need for superior strength and exceptional resistance to saltwater corrosion, Copper Nickel 7030 forgings from Nimish Metal provide a trusted, long-lasting solution for Kuwait’s key industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
