Al Vishwas Nickel Alloys, headquartered in Dubai, UAE, is a trusted manufacturer and supplier of Copper Nickel Stud Bolts, delivering high-quality fastening solutions for marine, industrial, and chemical uses. These stud bolts are engineered to provide exceptional corrosion resistance, remarkable tensile strength, and enduring durability, guaranteeing dependable performance even in demanding conditions. Al Vishwas Nickel Alloys follows rigorous quality standards to supply consistent and accurate products. Copper Nickel Stud Bolts are used in seawater piping, offshore structures, desalination plants, and chemical processing equipment, forming secure and long-lasting joints capable of withstanding aggressive media, mechanical stress, and continuous exposure to salty and corrosive environments.
Copper Nickel Stud Bolts are primarily composed of 90% copper and 10% nickel (CuNi 90/10) or 70% copper and 30% nickel (CuNi 70/30), along with small quantities of iron and manganese. This alloy is recognized for its outstanding resistance to seawater corrosion, pitting, and biofouling, while also delivering high tensile strength, toughness, and ductility. The bolts show impressive fatigue resistance, thermal conductivity, and dimensional stability. The combination of mechanical strength and corrosion resistance ensures reliable performance in marine, offshore, and industrial environments where high stress and severe conditions are frequent.
