They have good resistance to corrosion in sea water. They also have high strength and resist impingement corrosion. They also exhibit appreciable ductility and hardening is only possible through cold working. The nickel content enables them to exhibit appreciable strength at elevated temperatures. They also have a low temperature co-efficient of electrical resistance. Some alloys also resist biofouling.
They find applications in various sectors. They are used in sea water condenser systems and desalination systems, on account of good resistance to corrosion in sea water. Other marine applications like cladding for ships’ hulls, legs of oil rig platforms and sea water intake screens, also exploit this property.They are also used in making currency coins on account of good corrosion resistance. Copper nickel alloys are used in automotive applications like brake and hydraulic suspension systems and cooling systems in cars. Low temperature co-efficient of electrical resistivity makes them useful for making wires in high precision resistors. They also have other applications like cooling circuits, ammunition and condenser tubes.

This implies that we pay attention to the needs of our customers even after they have received the goods, through our after sales services. We have a special team which has been assigned the work of providing premium packaging to ensure that the products reach our clients in their best form. If, by any chance (however small it may be), the products fail to satisfy the customers, we immediately execute our product replacement scheme to ensure that they receive better. We also enjoy ISO 9001:2008, ISO 14001:2004, OHSAS 18001:2007 Certifications. All these factors have helped us gain the trust of consumers and we are continuously growing as leading producers and suppliers in the market. Today, we have distributors in more than 13 countries. We have the highest stock of steel and nickel based alloys in the country. The dispatch and replenishment go hand in hand to ensure that the stock is maintained. Thus, we prevent customers from facing the problem of unavailability of the raw material. We also never fail to provide the heat number on every product so that the consumer can trace the information about its history and applications. We maintain correct level of hardness. We are extremely accessible in terms of consultation about various sizes and grades of the alloys. We care for the environment as well. Scrap material is properly treated and converted into alloys of excellent quality. It is then incorporated in our stock. Once chosen by the customer, we leave no stone unturned to live up to our promise of making each penny paid by him count.
