corrosion resistance in the acid-based solutions and liquid metals, thus
improve its wear resistance, hardenability, weldability, and heat resistance.
As an element which easy to form carbides, molybdenum can effectively avoid
oxidation during steel making process, and it can be used alone or mix with
other alloy element to achieve the best performance.
A pure molybdenum rod is a cylindrical bar made entirely of molybdenum, a chemical element with the symbol Mo and atomic number 42. Molybdenum is a refractory metal known for its high melting point, excellent thermal conductivity, and resistance to corrosion. Pure molybdenum rods are commonly used in various applications, including the manufacturing of electrodes, heating elements, and high-temperature furnaces. They are also utilized in the aerospace, defense, and medical industries due to their exceptional mechanical and thermal properties.
