Monel Alloy Tubes

Monel alloy tubes are made primarily of nickel and copper, offering excellent corrosion resistance, high-temperature strength, and durability. They are widely used in marine engineering, chemical equipment, aerospace, and other fields. Monel alloy tubes perform well in harsh environments, especially in seawater, acidic media, and high-temperature conditions.
