Copper is well known for its high ductility, electrical and thermal conductivity, and high malleability. Hence Copper Nickel Fasteners are always in demand. They are available in 2 variety Copper Nickel 90/10 Fasteners which contain 90% Copper and 10% Nickel, and Copper Nickel 70/30 Fasteners which contain 70% Copper and 30% Nickel. Where the 70/30 version is resistant to seawater related corrosion.
Copper Nickel Bolts also resist acetic, and phosphoric acid. They also display resistance to pitting and excellent welding properties along with hydrogen embrittlement resistance and retention of mechanical properties even in cryogenic temperature. Furthermore, Cupro Nickel Bolts also provide oxidation resistance at 1600 degrees C for intermittent service and 1700 degrees F for continuous service.
Copper Nickel Nuts have an enormous amount of carbon content. This helps in applications that require maximum corrosion resistance as it restricts carbide precipitation. Nickel Copper Screws are used in the pulp and paper industry, chemical tankers, heat exchangers, and condenser tubes. It is also popular among marine, architecture, and industrial applications. These Copper Nickel Threaded Rod are amongst those who offer high creep, and stress-to-rupture resistance. To meet the mechanical property of straight grade a small portion of the nitrogen is added to Cu-ni Heavy Hex Nuts. This also helps in maintaining low carbon content.
Copper Nickel Fasteners produced at our factories are as per the national and international standards. We use the best raw material and provide these products to you at a competent price. Our team of professionals maintains and puts the product through various tests to ensure quality.
