With a commitment to quality and precision, Rupal Metals delivers Copper Nickel bars that adhere to international standards, making them perfect for marine, chemical, and power generation sectors. Their rectangular bars are built to withstand the harshness of seawater and corrosive environments, thanks to a carefully balanced composition. Rupal Metals prioritizes dependable delivery and customer-centric solutions, establishing themselves as a go-to source for Copper Nickel rectangular bars in demanding applications.
Copper Nickel Rectangular Bars are generally made up of 90% copper and 10% nickel (the 90/10 grade) or 70% copper and 30% nickel (the 70/30 grade), with small amounts of iron and manganese added to boost strength and corrosion resistance. These bars excel in resisting biofouling, erosion, and corrosion from seawater. Their mechanical properties include tensile strength ranging from 275 to 500 MPa, yield strength from 105 to 250 MPa, and an elongation of up to 30%. They also maintain good ductility, thermal stability, and weldability, making them a dependable choice for tough industrial and marine settings.
