Monel alloys generally consist of 63-70% nickel, 28-34% copper, and small amounts of iron, manganese, silicon, and carbon. These alloys show excellent resistance to seawater, acidic, and alkaline environments. Mechanical properties include a tensile strength of about 550-620 MPa, a yield strength of around 240-345 MPa, an elongation of about 30-40%, and hardness between 120-180 HB. Monel retains toughness across a wide range of temperatures, including cryogenic conditions. It offers great resistance to stress corrosion cracking and pitting, making it one of the most reliable nickel alloys for harsh marine and chemical processing environments.
