Here in Amman, Nizar Sheetsandplates stands as your trusted partner for high-quality marine alloys. We take pride in supplying robust Copper Nickel 7030 sheets and plates, a material specifically engineered to withstand the most demanding environments. Our commitment is to provide Jordanian industries and beyond with materials that deliver unmatched longevity and performance, backed by our deep understanding of the specific challenges faced in sectors like shipbuilding and offshore engineering.
At its heart, this alloy is a carefully balanced blend of approximately 70% copper and 30% nickel, with small additions of iron and manganese. This composition is the secret to its exceptional resistance to corrosion, especially in saltwater. The material offers excellent mechanical strength and toughness, and it remains remarkably ductile, making it easier to fabricate into complex components without sacrificing its integrity under stress.

Copper Nickel 70/30 Sheets and Plates offer excellent corrosion resistance, particularly in marine and industrial environments, making them ideal for seawater applications. Their high strength and excellent resistance to biofouling ensure longevity and reliability in harsh conditions. These materials also exhibit good thermal conductivity, making them suitable for heat exchange applications. The 70/30 alloy provides outstanding weldability, formability, and machinability, allowing easy customization and fabrication. Copper Nickel 70/30 Sheets and Plates also offer resistance to pitting, crevice corrosion, and stress corrosion cracking, enhancing durability and performance in diverse industries.
The primary use for our CuNi 7030 sheets and plates is in the marine world, where reliability is non-negotiable. You’ll find it forming critical parts of ship hulls, seawater piping systems, and heat exchangers because it resists biofouling and corrosion fatigue beautifully. Its applications also extend to coastal power plants and desalination facilities, where equipment must constantly battle aggressive saltwater. Essentially, wherever long-term exposure to seawater is a factor, this alloy provides a proven, durable solution that minimizes maintenance and maximizes uptime.
