Steve Flanges, a well-respected manufacturer and supplier located in Canberra, Australia, is renowned for providing top-notch Copper Nickel Blind Flanges that adhere to global standards for durability, corrosion resistance, and performance. These flanges are meticulously crafted from high-quality copper-nickel alloys, ensuring exceptional strength and reliability, particularly in marine and offshore settings. With cutting-edge manufacturing techniques and rigorous quality control, Steve Flanges produces flanges that boast impressive dimensional accuracy and leak-proof sealing capabilities. Their Copper Nickel Blind Flanges are perfect for applications that demand long-lasting, maintenance-free solutions, even in harsh environmental and pressure conditions.
Copper Nickel Blind Flanges are mainly made up of copper and nickel, with small amounts of iron and manganese added to boost mechanical strength and corrosion resistance. The most common grades are Cu-Ni 70/30 (70% copper, 30% nickel) and Cu-Ni 90/10 (90% copper, 10% nickel). These flanges excel in resisting seawater, brine, and various corrosive chemicals. They offer good tensile strength, ductility, and toughness, maintaining stability even under high temperatures and pressures. Their non-magnetic and anti-biofouling characteristics make them especially suitable for marine and industrial applications.
