Neil Metals, located in Kolkata, India, has built a solid reputation as a manufacturer and supplier of top-notch Copper Nickel Bright Bars. These bars are celebrated for their outstanding corrosion resistance, durability, and smooth surface finish. With a strong focus on quality and precision, Neil Metals offers these bars in various grades, including 70/30 and 90/10, to meet the needs of industries that demand high performance. Manufactured to comply with international standards, these bright bars can be customized in size and finish. Neil Metals proudly serves key sectors such as marine, offshore, chemical processing, and power generation, providing reliable solutions along with timely delivery and exceptional customer service.
Copper Nickel Bright Bars are primarily made up of copper (60–90%) and nickel (10–30%), often with added iron and manganese to boost their strength and corrosion resistance. They excel in resisting seawater and biofouling. In terms of mechanical properties, these bars offer tensile strength between 400–600 MPa, yield strength around 150–250 MPa, and elongation of up to 35%. They also maintain good thermal conductivity, workability, and strength even under pressure and high temperatures, making them perfect for tough and corrosive environments in both marine and industrial applications.
