Frequently Asked Questions

What is NCC-40%?

NCC-40% is a standard grade of Nickel-Clad Copper with 40% IACS conductivity, manufactured using clad and weld process with metallurgical bonding. It provides excellent corrosion resistance and high-temperature performance.

What are the main applications of NCC-40%?

NCC-40% is primarily used in alkaline electrolysis systems, resistance welding electrodes, aerospace components, and other applications requiring corrosion resistance and high-temperature stability.

How does NCC-40% differ from NCC-50%?

NCC-40% has higher nickel content (35-45%) providing better corrosion resistance, while NCC-50% has higher conductivity (48-52% IACS) with lower nickel content (25-35%). The choice depends on whether corrosion resistance or conductivity is the priority.

What is the maximum operating temperature for NCC-40%?

NCC-40% can operate continuously at temperatures up to 400°C, making it suitable for high-temperature applications like welding electrodes and industrial heating systems.

Is NCC-40% suitable for alkaline environments?

Yes, NCC-40% is specifically designed for harsh alkaline environments such as KOH solutions in alkaline water electrolysis, where its nickel cladding provides excellent long-term corrosion resistance.
