Affordably priced supplier of Cupro Nickel 90/10 Threaded Rod and Stud bolts in India

The Copper Nickel Hex Bolts are made up of an alloy which is an ideal mix of copper and nickel, with trace amounts of manganese, iron, etc. The Copper Nickel Bolts are widely used for fighting seawater corrosion. Manufacturers should always use high quality raw materials to make these, so that they are durable and can give their optimal performance. These bolts are quite popularly used across several industries.
The Cupro Nickel Bolts are generally found in different application industries like hardware, paper, oil and gas, and so on. These bolts can be easily customized in terms of their thickness and sizes, and are made according to the specifications given by the client. Customers should compare the prices of these bolts from different manufacturers before making the purchase.
The Cupro Nickel Threaded Rod is known for its properties such as high corrosion resistance and electrical conductivity. They are quite durable, malleable, and come with ease of stamping. The UNS C70600 Stud Bolt possesses antimicrobial properties and they are recyclable too. Their good formability makes it easy to bend or flare them. Even though the price of the UNS C71500 Flange Bolt is slightly higher than that of the steel alternatives, the money is totally worth it. They have a long service life and can be installed quite easily. They are very safe for a variety of usages. The Cunifer Socket Head Cap Screw comes with improved strength and shows good corrosion resistance along with high ductility.
The CuNi products are available in two variants which is due to the difference in their chemical composition. The CuNi 90/10 Nuts has 90% copper and 10% nickel, and they are high in strength and corrosion resistance. The Cupro Nickel 90/10 Screws are also ductile with improved toughness and that is why they are used in various marine, industrial and architectural applications. The CuNi 70/30 Fasteners, on the other hand, has 70% copper and 30% nickel. They show high resistance to seawater corrosion due to the presence of manganese and iron in its composition.
