MONEL Alloy 400
MONEL Alloy 400 is a high-performance nickel-copper alloy renowned for its exceptional strength, toughness, and resistance to corrosive environments. Designed for reliability across a wide temperature range, it is the trusted choice in marine, chemical, and oil & gas industries. Offers remarkable resistance to seawater, hydrofluoric acid, and other aggressive chemicals, making it ideal for marine components and chemical processing. Maintains high tensile and yield strength from subzero temperatures to elevated heat, without compromising ductility or toughness. Depending on composition, MONEL 400 by Special Metals may be magnetic or non-magnetic at room temperature. For critical non-magnetic applications, alternate MONEL grades are available.
