CuNi70/30 Copper Nickel Plate Anti Seawater Corrosion Cupro Nickel Sheet For Marine Equipment
1. Product Overview
CuNi 70/30 Copper Nickel Plate, also known as cupronickel alloy sheet, is a high-precision metal plate manufactured in strict accordance with ASME B16.5 and UNS C71500 international standards. It is composed of 70% copper and 30% nickel with trace alloy elements, adopting integrated hot rolling and fine polishing technology. Different from ordinary metal plates, this copper nickel plate features uniform internal structure, no impurity segregation, stable chemical performance and excellent flatness. It undergoes strict heat treatment process to eliminate internal stress, ensuring no deformation during cutting, bending and welding processing. It is a premium raw material widely used for marine corrosion-resistant manufacturing and industrial equipment processing.

3. Application Scope & Product Function
This 70/30 copper nickel plate serves as a core anti-corrosion structural material, mainly functioning as equipment shell, liner, welding processing raw material and corrosion-resistant structural plate. It is widely applicable in marine ship hull accessories, offshore platform equipment, seawater desalination devices, chemical corrosion-resistant tanks, power plant heat exchange equipment and petrochemical engineering facilities. The product can effectively isolate seawater, acid and alkali corrosive media, protect equipment structure from rust and damage, and support secondary processing such as cutting, bending and welding to make various alloy parts.
4. Product Core Advantages
Superior Corrosion Resistance: Professional marine-grade alloy formula resists seawater erosion and chemical corrosion, solving the short service life problem of carbon steel plates in harsh environments.
Excellent Machinability: Uniform texture and moderate hardness support flexible cutting, stamping and welding, no cracking during secondary processing, high processing yield.
High Structural Stability: After precise annealing treatment, the plate has low internal stress, good flatness and high temperature resistance, suitable for long-term outdoor and high-temperature working conditions.
Premium Surface Quality: Smooth and burr-free surface, no oxidation spots, easy for subsequent painting and bonding processing.
5. Packaging, Delivery & After-sales Service
We adopt standard export packaging with waterproof paper, plastic film and wooden box reinforcement to avoid scratch, oxidation and deformation during long-distance transportation. Flexible payment terms and fast global delivery are available, with in-stock supply for conventional sizes and customized processing for special specifications. All products are fully inspected with complete quality certification reports. We provide professional processing guidance and support sample orders and bulk purchases. Complete after-sales service covers product return and exchange for quality issues. Contact us now to get the latest factory wholesale price and free technical support!
