Fajar Metals, based in Jakarta, Indonesia, stands out as a top manufacturer and supplier of high-performance Copper Nickel 70/30 Sheets and Plates, perfect for marine, offshore, and industrial uses. This alloy, made up of 70% copper and 30% nickel, boasts impressive strength, corrosion resistance, and durability, especially in tough seawater conditions. Fajar Metals offers these Cu-Ni 70/30 sheets and plates in a variety of thicknesses, sizes, and tempers, all adhering to international standards like ASTM B122, B171, and MIL-C-15726. They’re ideal for crafting components that require exceptional corrosion resistance, structural integrity, and long-lasting performance in marine and heat-exchange systems.
Copper Nickel 70/30 Sheets and Plates are composed of 70% Copper (Cu) and 30% Nickel (Ni), with carefully controlled amounts of Iron (Fe) and Manganese (Mn) to boost strength and corrosion resistance. These materials provide a tensile strength ranging from 320 to 420 MPa, a yield strength of 120 to 180 MPa, and showcase excellent formability and toughness. Their ability to resist pitting, stress corrosion cracking, and biofouling in saltwater makes them perfect for demanding marine environments. Additionally, Cu-Ni 70/30 offers outstanding thermal conductivity, weldability, and oxidation resistance, making it a great choice for pressure-retaining and high-heat applications.
