Fajar Metals, a top-notch manufacturer and supplier located in Jakarta, Indonesia, specializes in high-quality Copper Nickel 70/30 Forged Fittings that are built to perform exceptionally in marine, chemical, and industrial settings. Made up of 70% copper and 30% nickel, these fittings boast impressive corrosion resistance, especially in seawater and brine conditions. Fajar Metals offers a diverse selection of forged fittings, including elbows, tees, couplings, unions, and reducers, all crafted to meet international standards like ASTM B151, B467, and ASME B16.11. Renowned for their strength, durability, and thermal stability, Cu-Ni 70/30 forged fittings guarantee secure, leak-proof connections in demanding systems.
Copper Nickel 70/30 Forged Fittings consist of 70% Copper (Cu) and 30% Nickel (Ni), with small amounts of Iron (Fe) and Manganese (Mn) added to boost mechanical strength and corrosion resistance. These fittings showcase a tensile strength between 320–420 MPa and a yield strength of 120–180 MPa, making them perfect for high-pressure situations. They effectively resist stress corrosion cracking, pitting, and biofouling, particularly in salt-rich and high-flow environments. Cu-Ni 70/30 also maintains excellent thermal conductivity, weldability, and fabrication characteristics, ensuring a long service life in systems that encounter marine or chemically aggressive fluids.
