Fajar Metals, a well-respected manufacturer and supplier located in Jakarta, Indonesia, specializes in high-quality Copper Nickel Screws that are built to perform exceptionally well in corrosive and marine environments. Crafted from robust Cu-Ni 90/10 and 70/30 alloys, these screws are perfect for applications in shipbuilding, desalination, offshore projects, and various industrial systems. Fajar Metals offers a diverse range of screw types—including machine screws, self-tapping screws, and socket head screws—that comply with international standards like ASTM B151, B467, and DIN/ISO specifications. Renowned for their outstanding corrosion resistance, strength, and longevity, these screws ensure secure fastening even in challenging, moisture-laden conditions.
Copper Nickel Screws are mainly made up of 90% Copper and 10% Nickel (Cu-Ni 90/10) or 70% Copper and 30% Nickel (Cu-Ni 70/30), with small amounts of Iron (Fe) and Manganese (Mn) added to boost their strength and resistance to corrosion. These screws provide impressive tensile strength ranging from 275 to 420 MPa and yield strength between 105 and 180 MPa, along with remarkable ductility and thermal stability. They are highly resistant to chloride-induced corrosion, biofouling, and pitting, making them ideal for submerged applications and harsh chemical environments, ensuring reliable performance in both structural and precision fastening tasks.
