Copper Nickel Busbar C71500, also known as CuNi70/30, is a high-performance copper-nickel alloy composed of approximately 70% copper and 30% nickel. This alloy stands out for its exceptional resistance to seawater corrosion, high mechanical strength, and thermal stability. It’s commonly used in marine, offshore, power distribution, and chemical processing industries where both durability and conductivity are essential.
At DZX, our C71500 busbars are precision-engineered with advanced melting and extrusion technology to ensure a uniform structure, tight tolerance, and excellent surface finish. Each piece meets international standards such as ASTM B151, EN 12163, and DIN 17664, ensuring performance consistency and compatibility with global engineering applications.
C71500 busbars are widely used in:
Marine and shipbuilding: grounding bars, switchboards, and power connectors in ships and submarines.
Offshore platforms: power distribution systems exposed to seawater and humidity.
Desalination and water treatment plants: for corrosion-proof electrical connections.
Chemical processing plants: where resistance to acids and alkalis is required.
Renewable energy systems: offshore wind, tidal power, and ocean-based installations.
Its superior corrosion and biofouling resistance make it ideal for continuous operation in aggressive marine environments.
The global trend toward offshore renewable energy and smart marine systems is rapidly increasing the demand for copper-nickel alloys in electrical components. C71500, with its high nickel content, offers even greater corrosion resistance than C70600 (CuNi90/10).
As industries aim for long-term reliability, low maintenance, and sustainable materials, Copper Nickel C71500 has become a top choice for advanced engineering projects. Its blend of mechanical robustness and electrical conductivity provides a clear advantage over standard copper or aluminum busbars.
The future of power infrastructure—especially in marine and coastal regions—is moving toward CuNi70/30-based solutions for maximum service life and cost efficiency.

When it comes to electrical systems that operate in harsh, corrosive, or high-humidity conditions, few materials can match the durability of Copper Nickel C71500. As a CuNi70/30 alloy, it combines strength, corrosion resistance, and reliability—making it a trusted solution for critical power systems at sea and on land.
At DZX, we specialize in precision-engineered copper-nickel busbars that deliver performance where it matters most. Each C71500 busbar is made using refined melting and hot-extrusion processes to ensure consistent microstructure and long-lasting mechanical integrity. Whether it’s powering an offshore platform or grounding a naval vessel, our products guarantee stable electrical performance with zero compromise on safety.
One of the biggest challenges in marine and offshore power systems is corrosion. Constant exposure to seawater and salt-laden air causes rapid degradation in standard copper or aluminum busbars. CuNi70/30 solves this issue thanks to its high nickel content, which forms a stable oxide film that protects the metal even under continuous immersion. This translates into lower maintenance costs, reduced downtime, and longer equipment life.
From an engineering standpoint, the balance of copper and nickel provides not just corrosion resistance but also excellent thermal conductivity and mechanical strength. DZX’s C71500 busbars maintain their shape and conductivity even under fluctuating temperatures and currents, ensuring consistent power delivery in mission-critical systems.
As industries move toward greener, more sustainable energy solutions, offshore and coastal installations are expanding rapidly. Power infrastructure in these environments demands materials that can withstand extreme stress. DZX’s CuNi70/30 busbars are part of this new era—supporting renewable energy projects, desalination systems, and marine transportation networks across the world.
But what really sets DZX apart is our commitment to customization and precision. We don’t just supply standard materials—we collaborate with engineers to create tailor-made solutions that perfectly fit project specifications.
