Main features: The machining monel alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and it also has excellent corrosion resistance to hot concentrated alkali. It is also resistant to corrosion by neutral solutions, water, seawater, atmosphere, organic compounds, etc.
Monel400 alloy chemical composition is mainly composed of 30%Cu and 65%Ni plus a small amount of Fe (1%-2%). 400 is a corrosion-resistant alloy with the largest dosage, the most versatile application and excellent comprehensive performance.
Monel machining is a single-phase solid solution Ni-Cu alloy, which has good corrosion resistance in many media environments. From a mild oxidizing medium environment to a neutral environment to a suitable reducing environment, all have good corrosion resistance. This alloy has a long history of use as a corrosion-resistant material. In the early 20th century, people tried to smelt alloys with nickel ore with high content of copper. The proportion of nickel and copper in Monel400 is similar to the original ore.
