Catering to sectors like marine engineering, chemical processing, oil and gas, and industrial machinery, the company is committed to delivering dependable copper-nickel solutions across Central Africa. Their unwavering dedication to quality, timely delivery, and technical support makes them a go-to supplier for high-performance Copper-Nickel Bright Bars.
Copper-Nickel Bright Bars are generally made up of 60% copper and 40% nickel (CuNi 60/40), with small amounts of iron and manganese added to boost corrosion resistance. This alloy is known for its outstanding resistance to seawater and chemical corrosion, along with impressive strength and toughness. Mechanical properties include a tensile strength ranging from 380 to 550 MPa, yield strength between 100 and 300 MPa, and elongation of 30 to 50%, depending on the temper. The bars are bright, smooth, and highly formable, making them ideal for machining, forging, and fabricating critical components for marine, industrial, and chemical applications.
