Monel Buttweld Fittings are primarily made up of Nickel (63–70%) and Copper (28–34%), along with small amounts of Iron, Manganese, Silicon, and Carbon. This unique alloy offers exceptional resistance to seawater, acids, and alkalis. The typical tensile strength falls between 550 to 620 MPa, with a yield strength around 240 MPa and an elongation of about 30–35%. They also have a Brinell hardness ranging from 70 to 100 HB. These impressive mechanical properties make Monel Buttweld Fittings incredibly durable, pressure-resistant, and well-suited for demanding industrial applications that involve fluctuating thermal and chemical conditions.
