Cupro Nickel 70/30 Bars are highly sought after in the manufacturing industry due to their exceptional characteristics. They are composed of copper and nickel and are popular due to their high strength and excellent corrosion resistance. These bars are available in shapes like round, hexagonal, square, and forged, making them usable in various applications.
Features of Cupro Nickel 70/30 Round Bars:
Cupro Nickel 70/30 round bars are known for their high strength, excellent flexibility, and resistance to stress corrosion cracking. These bars can be easily welded, brazed, and soldered, making them suitable for different types of fabrication. They are also resistant to erosion, corrosion, and biofouling, making them suitable for use in marine environments. Moreover, these bars also have high thermal conductivity and low thermal expansion, making them ideal for heat exchangers and condensers.

Corrosion Resistance of Cupro Nickel 70/30 Hex Bars:
Cupro Nickel 70/30 hex bars have exceptional resistance to seawater, brackish water, and other corrosive solutions. Even in harsh conditions, they show no evidence of crevice corrosion or pitting. Their excellent corrosion resistance is due to natural oxidation layers on the bars' surface that protect them from corrosion. That makes them an ideal choice for manufacturers looking for corrosion-resistant materials.
Chemical Composition of Cupro Nickel 70/30 Square Bars:
Cupro Nickel 70/30 square bars have a chemical composition of 70% Copper and 30% Nickel. They also contain trace amounts of other elements, such as iron, manganese, and chromium. Along with copper and nickel, these elements provide Cupro Nickel 70/30 with unique characteristics such as excellent corrosion resistance and high strength.
Machining of Cupro Nickel 70/30 Forged Bars:
Cupro Nickel 70/30 forged bars are easily machinable and can be hot and cold worked. They can be cut, drilled, and turned easily using standard machining tools. However, it is essential to use lubricants when machining these bars to prevent chips from sticking to the tool. Additionally, carbide or high-speed steel cutting tools are recommended as they can handle the high strength of Cupro Nickel 70/30.
