Copper Nickel 90/10 Bolts


Copper Nickel 90 / 10 Bolts

Cupro Nickel 90/10 bolts are a perfect combination of copper and nickel, with the addition of Manganese and other ferrous elements such as iron to combat seawater corrosion. Cupro Nickel 90/10 fasteners are highly available in environments that contain chloride or other halogens, such as marine environments. They have good oxidation resistance upto 1600 degrees Fahrenheit and continue services upto 1700 degrees Fahrenheit.

Cupro Nickel 90/10 Stud Bolts has a high carbon content that restricts carbide precipitation during welding and applications requiring high corrosion resistance. Compared to other alloys, it also has better creep deformation characteristics and mechanical resistance to high temperatures. At elevated temperatures, these have high creep, stress to rupture, and tensile strength. They are used in chemical tankers, paper equipment, and other applications. Due to its high corrosion resistance property, it is widely used in the industry.

Cupro Nickel 90/10 meets the metallic properties of the straight grade while maintaining a low carbon content due to the controlled addition of nitrogen. These Cupro Nickel 90/10 Nuts are designed according to the national and international raw material quality standards and guidelines.

The high oxidation rate of Cupro Nickel 90/10 Screw is evident in steam and moist air. The addition of chromium, niobium, iron, or Manganese to the Cupro Nickel 90/10 bolt increases its corrosion resistance and strength. These are naturally resistant to biofouling as well as they have excellent fabricability. They even have thermal stability even at high temperatures.

DC Engineering is one of the most trusted and modest suppliers, manufacturers and stockists of Cupro Nickel 90/10 bolts. These bolts are thoroughly made of tested and certified raw materials. Our professionals rigorously test these bolts. We are known for the accuracy in dimensions, sizes and shapes of our products. We always consider international and national standards while manufacturing each product.
