Nestled in the industrial heart of Amman, Jordan, Nizar Sheetsandplates has built a reputation for precision and reliability in the supply of specialized metals. We take particular pride in offering high-quality Copper Nickel 7030 Foil, a material chosen by discerning industries for its exceptional performance in demanding environments. Our commitment is to provide not just a product, but a trusted solution, backed by deep expertise and a dedication to meeting the specific needs of our clients across the region and beyond.
This particular alloy, often referred to as Cupro Nickel 70/30, is primarily composed of about 70% copper and 30% nickel, with small additions of iron and manganese that significantly enhance its strength. These elements work in concert to give the foil remarkable mechanical properties, including excellent tensile strength and outstanding ductility. This combination allows it to be rolled into extremely thin, flexible sheets without sacrificing its structural integrity, making it both strong and highly workable for intricate applications.

Copper nickel 70/30 foil provides excellent corrosion resistance, especially in seawater and marine environments, making it ideal for shipbuilding, desalination and offshore applications Its high strength and delivery the durability ensures longevity even in harsh conditions. The excellent thermoelectric conductivity of the alloy makes it suitable for heat exchangers and electrical components. In addition, it resists biofouling, reduces maintenance costs, and improves productivity. The 70/30 configuration provides a balance of flexibility and rigidity, allowing for ease of manufacture while maintaining its design integrity in demanding applications.
The true value of this foil is realized in its wide-ranging uses, particularly where resistance to corrosion is paramount. It is indispensable in marine engineering for critical components like condenser tubes and ship hulls, and it’s equally vital in desalination plants where saltwater is a constant factor. Beyond the water’s edge, its superb resistance to biofouling and thermal conductivity makes it a smart choice for heat exchangers and power generation systems, ensuring longevity and reliability in some of the most challenging industrial settings.
