Copper Nickel Wire CuNi Alloy CuNi8/NC012/C71500 Senphus Flexibile Industrial Heating Solutionsfor Precise Temperature Control in Diverse Heating Applications
CuNi8 is a copper-nickel alloy containing approximately 92% copper and 8% nickel, with small amounts of iron and manganese to enhance its strength and corrosion resistance. This alloy is known for its exceptional performance in marine and industrial environments due to its resistance to seawater corrosion, biofouling, and erosion. CuNi8 also offers good mechanical strength and ductility, making it suitable for applications requiring durability and ease of fabrication.
CuNi8’s balance of strength, corrosion resistance, and thermal properties makes it ideal for demanding environments such as marine, industrial, and electrical applications.
