Monel belongs to the group of alloys based on nickel. The composition of Monel consists of nickel and copper with smaller amounts of carbon and silicon. These alloys are fabricated using hot-cold-working, machining, and welding, as well. Monel is also known for its resistance to many corrosive agents, which includes rapidly flowing seawater.
Monel is a costly alloy and is used only for limited applications. Monel is also difficult to machine and work hardens quickly making it difficult to use. K-500 Monel is a type of Monel alloy with aluminum and titanium additions, which give it greater strength. Whereas, Monel 400 alloy executes amazing mechanical properties at sub-zero temperatures. Monel is used in the aerospace industry for aircraft construction as it can resist the heat generated due to friction during extremely high-speed flights. Monel alloy also has good resistance to hydrofluoric acid. It is used in many chemical industries to contain concentrated amounts of hydrofluoric acid. The alloy is also resistant to sulphuric acid and hydrochloric acids in many forms under reducing conditions.
Monel Industrial Metals have a Harmonized Tariff Schedule (HTS) code of 74090200.
Monel Industrial Metals can be welded using a combination of manual and automatic welding techniques, such as oxy-acetylene welding, shielded metal arc welding and Gas Tungsten Arc Welding (GTAW).
Monel Industrial Metals are not magnetic but exhibit weak magnetism when placed in a strong magnetic field.
Monel has a melting point range of 1300-1390°C (2372-2534°F). At its lowest, the metal remains solid but highly malleable and at its highest, it is fully molten.
Monel exhibits high thermal conductivity, typically ranging between 65–108 W/mK. This is because it mainly consists of copper and nickel, which are both excellent heat transfer materials. Additionally, the alloy has a low electrical resistivity which helps enhance its overall thermal properties.
