Ismail Flanges caters to various industries, including shipbuilding, offshore oil & gas, desalination plants, and heat exchanger systems, ensuring quick delivery, competitive pricing, and unparalleled customer support for clients in Indonesia and around the world.
The Copper Nickel 70/30 Flanges from Ismail Flanges are made from a copper-nickel alloy that consists of 70% copper and 30% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. These flanges have impressive mechanical properties, featuring a minimum tensile strength of 283 MPa, a yield strength of at least 131 MPa, and an elongation of 30%. They demonstrate excellent ductility, impact strength, and resistance to erosion in high-velocity seawater. The alloy’s thermal stability and non-magnetic characteristics make it an ideal choice for marine and industrial piping systems that face harsh environments.
