Cupro Nickel Density & Price per KG in India

With reference to Cupro Nickel Density & Price per KG in India, the Density of Copper-Nickel is 0.323 lb/in³ (8.94 g/cc). Cupro Nickel price per kg in India is Rs 560. That means that the price of Cupro Nickel per kg would be roughly around 6.30 Pounds. Of course, this would not mean that Cupro Nickel would be available at this very same price in other parts of the globe such as USA, Singapore, China, Japan, Europe, UK, etc. For instance, the price of Cupro Nickel is roughly 5% higher in India, than it is in China. Yet, you could buy Cupro Nickel in India, for 35% lesser than you could buy it in America. Also, the price of Cupro Nickel is always fluctuating.

Why copper-nickel is required in Navy?

The reason why copper-nickel is required in Navy is because it shows excellent corrosion resistance to sea water, it has low macrofouling rates and it also has superb fabricability. As copper-nickel is resistant to sea water, it is used in hulls, propellers and crankshafts of fishing boats, tugboats, working boats and other types of boats. Copper-nickel is also used in marine hardware and in seawater system condensers.

Where are copper-nickel scrap buyers & why?

The answer to where are copper-nickel scrap buyers & why, is that there are scrap buyers of copper-nickel located all over the globe. The reason for this is because there is a huge demand for copper-nickel all over the world, as it is used in many applications and industries. Copper nickel scrap plays a very important role in many different kinds of industries, all over the globe. Also, there is a lot of money to be made from selling and trading in copper nickel scrap. This is why there are so many sellers and traders of copper nickel scrap today, selling this kind of scrap, in all parts of the globe.
