Cupro Nickel 90/10 Hex Bolts and Heavy Hex Nuts manufacturer in India, Cu-Ni 70/30 Studs can be produce as required with short lead times.

Copper Nickel Fasteners

 

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.

 

What Do You want from Your Manufacturer of Copper Nickel Fasteners?

  • No limitation of least amount; We adore to supply even a single Nut bolts in any grade of Copper Nickel
  • First supplier ought to be veritable & trusted: Siddhagiri Metals is 20 year ancient supplier and providing to most presumed oil and gas companies in Saudi Arabia, lng projects in Qatar, Africa, Russia, Europe and South America.
  • My Measure and Length: After you find Copper Nickel Fasteners the primary thing you anticipate that in case you get it in your size so you do not got to pay additional for waste material. We at Siddhagiri give cut to size so we have a huge stock of custom size cupro nickel bolts and nut. Chances are high that you simply get your size which saves a lot of cash.

 

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.
