What is a C71500 copper nickel tube?
Copper-nickel alloy C71500, also known as 70/30 alloy, is composed of 70% copper and 30% nickel, with added iron and manganese, giving it excellent corrosion resistance and erosion resistance. C71500 has a higher nickel content than C70600, thus exhibiting superior corrosion resistance, making it particularly suitable for marine environments and ensuring a long and reliable service life for components under these conditions. GNEE is a leading supplier of copper-nickel alloy C71500, primarily supplying tubing conforming to ASTM B466/B111 standards, as well as various sizes and specifications of ASTM B122 C71500 sheet metal.
