Adrian Nickel Alloys, based in Pulau Ujong, Singapore, stands out as a top-notch manufacturer and supplier of Copper Nickel 70/30 bolts. These high-quality fasteners are crafted for exceptional durability, making them perfect for tough marine and industrial settings. Adhering to international standards, our bolts boast impressive resistance to corrosion, biofouling, and high-pressure situations. We proudly serve a variety of industries, including shipbuilding, desalination, offshore structures, and power generation, providing reliable and high-performance copper-nickel fasteners.
Our Copper Nickel 70/30 bolts are made up of about 70% copper and 30% nickel, with a touch of iron and manganese to boost their mechanical strength and corrosion resistance. This alloy is known for its outstanding resistance to seawater corrosion, erosion, and stress corrosion cracking, even in rough or fast-moving marine environments. We manufacture these bolts in line with standards like ASTM B151, ASME SB151, and DIN 2.0882, with tensile strength varying from 310 to 480 MPa based on their condition and size.
