Fajar Metals, a leading manufacturer and supplier located in Jakarta, Indonesia, specializes in top-quality Copper Nickel Bolts that are known for their durability and resistance to corrosion, making them perfect for both marine and industrial uses. Available in Copper Nickel 90/10 and 70/30 grades, these bolts are engineered to endure tough conditions, including exposure to saltwater and high-pressure environments. Fajar Metals offers a diverse selection of bolt types, such as hex bolts, anchor bolts, stud bolts, and machine bolts, all meeting international standards like ASTM, DIN, and ISO. These bolts deliver exceptional performance and reliability for long-term use in critical applications.
Copper Nickel Bolts are made from either 90% Copper (Cu) with 10% Nickel (Ni) or 70% Copper (Cu) with 30% Nickel (Ni), along with small amounts of Iron (Fe) and Manganese (Mn) to boost their mechanical strength and resistance to corrosion. They showcase a tensile strength ranging from 350 to 450 MPa, a yield strength of 150 to 200 MPa, and impressive elongation and toughness. These bolts remain stable in challenging conditions characterized by high chloride levels, rapid flow, and fluctuating temperatures, making them ideal for crucial fastening tasks in demanding marine and chemical processing settings.
