Nickel-Copper Alloy
Monel400 is an alloy material with nickel and copper as the main
components. It has excellent corrosion resistance and mechanical
properties and is widely used in many industrial fields. The
following is a detailed description of Monel400:
1. Chemical composition
Monel400 is mainly composed of about 65% nickel (Ni) and 30% copper (Cu), and contains a small amount of iron (Fe), usually between 1% and 2%. Nickel and copper can be mutually dissolved in any proportion, so there is generally no intermetallic phase precipitation.
2. Corrosion resistance
Monel400 performs well in a variety of corrosive media, including:
Acidic media: such as sulfuric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid and organic acids.
Alkaline media: such as sodium hydroxide solution.
Salt solutions: such as seawater and molten salt.
Other media: such as ammonia, sulfur, chlorine and hydrogen
chloride.
3. Mechanical properties
Monel400 has high tensile strength (σb ≥ 450Mpa) and yield strength
(σb ≥ 170Mpa), and elongation (δ ≥ 30%), which enables it to adapt
to various complex working conditions.
4. Physical properties
Density: about 8.8g/cm³.
Melting point: between 1450°C and 1560°C.
Coefficient of thermal expansion: about 13.9×10^-6/°C between
room temperature and 300°C.
5. Application areas
Monel400 is widely used in the following fields due to its
excellent performance:
Chemical processing: used to manufacture corrosion-resistant
equipment and pipelines.
Marine engineering: used for seawater desalination equipment and
ship components.
Aerospace: used to manufacture key components.
Oil and gas: used for drilling equipment and pipeline systems.
6. Other properties
High temperature resistance: Monel400 can maintain its structural
stability and mechanical properties at high temperatures.
Wear resistance: It can withstand friction and wear, and is
suitable for the manufacture of parts that require high wear
resistance.
Electrical conductivity: It has good electrical and thermal
conductivity, and is suitable for electronic devices and
heat-conducting equipment.
In summary, Monel400 is a nickel-copper alloy with excellent
performance, which plays an important role in many industrial
fields.
