Frequently Asked Questions
What is copper-nickel 90/10 price?
The price of Copper-Nickel 90/10 varies based on quantity, form, and market rates. For the latest pricing, please contact Lakshya Steel directly to get an accurate and updated quote.
What is the difference between 90/10 and 70/30 copper-nickel?
CuNi 90/10 is more economical and offers good corrosion resistance and thermal conductivity, ideal for standard marine piping and heat exchangers. CuNi 70/30 provides higher strength and better performance in aggressive or high-velocity seawater, commonly used in offshore and desalination systems.
What type of anti-seize is best?
Nickel Grade Anti-Seize is widely recommended as it protects metal components from corrosion, galling, and seizure. Made with nickel and graphite, it performs reliably at temperatures up to 2600°F and offers excellent chemical and oxidation resistance.
What is the equivalent of 90/10 copper-nickel?
The equivalent of copper-nickel 90/10 is commonly referred to as CuNi10 under EN standards and UNS C70600, both representing the same alloy composition and properties.
