Pengkumta Fasteners is an expert in producing and delivering premium quality Copper Nickel Stud Bolts to resist harsh environments where corrosion resistance is needed. Constructed from a combination of nickel and copper alloys, Pengkumta’s Copper Nickel Stud Bolts are very resistant to corrosion in seawater and other aggressive chemical environments. They are extensively applied in the marine, offshore, and industrial industries where enhanced performance under heavy stress is crucial. Pengkumta’s Copper Nickel Stud Bolts offer superior tensile strength, enduring durability, and dependable performance, making them the first choice for industries that demand strong and corrosion-resistant fasteners.
The Copper Nickel Stud Bolts consist of a copper-nickel alloy with 70% copper and 30% nickel. The alloy provides superior corrosion resistance, especially in seawater and severe chemical environments. The stud bolts possess excellent tensile strength (up to 600 MPa) and outstanding stress corrosion cracking resistance, which is perfect for demanding applications. Being hard up to 250 HB, they also exhibit superior resistance to wear. The copper-nickel alloy guarantees the reliability of these bolts in high-temperature and high-pressure conditions in marine and offshore industries.
