Santner Nickel Alloys, based in Hamilton, New Zealand, is a reliable manufacturer and supplier of Copper Nickel Stud Bolts, providing top-notch fastening solutions for marine, industrial, and chemical applications. These stud bolts are designed to offer outstanding corrosion resistance, impressive tensile strength, and long-lasting durability, ensuring they perform reliably even in tough environments. Santner Nickel Alloys adheres to strict quality standards to deliver consistent and precise products. Copper Nickel Stud Bolts find their place in seawater piping, offshore structures, desalination plants, and chemical processing equipment, creating secure and durable joints that can handle aggressive media, mechanical stress, and constant exposure to salty and corrosive conditions.
Copper Nickel Stud Bolts are mainly made up of 90% copper and 10% nickel (CuNi 90/10) or 70% copper and 30% nickel (CuNi 70/30), with trace amounts of iron and manganese. This alloy is known for its excellent resistance to seawater corrosion, pitting, and biofouling, while also providing high tensile strength, toughness, and ductility. The bolts demonstrate remarkable fatigue resistance, thermal conductivity, and dimensional stability. The blend of mechanical strength and corrosion resistance guarantees dependable performance in marine, offshore, and industrial settings where high stress and harsh conditions are common.
