Molybdenum rod: A rod made from molybdenum powder by melting, forging and pressing. The production methods are electric furnace method, reflection furnace method and continuous ingot casting method.
Molybdenum electrode rod: A slender rod made of molybdenum as the main raw material through the process of melting, forging and electrode extrusion, mainly used as anode in electrolysis and electroplating industries.
Molybdenum wire: Molybdenum wire is drawn into the wire. It is divided into lead and zinc fiber wire, glossy wire, polished wire and fried wire. It is mainly used as a manufacturing material for electrical switches, circuit breakers and other products.
Mechanical properties of forged molybdenum rods:
Tensile strength: The tensile strength of forged molybdenum rods is about 1200-1500 MPa.
Bending strength: The bending strength of forged molybdenum rods is about 800 to 1000 MPa.
Fracture toughness: the fracture toughness of forged molybdenum bar is about 4~5 J/cm2.
Thermal conductivity: the thermal conductivity of forged molybdenum rods is 150～1600 W/(m-K).
Corrosion resistance: Molybdenum is very stable in air and stable in oxidizing and reducing atmospheres. Therefore, it is commonly used to make high-temperature and high-corrosion resistant devices such as hydrogenation reactors, heating furnace tubes, high-temperature incinerators and dryers in the petrochemical industry.
Molybdenum has no effect on the weldability of steel, can be welded with various steel welding rods, and does not require special protection measures after welding.
Molybdenum is difficult to machine and is prone to sticky tools during machining, so it is often processed using ceramic fixtures, special grinders, etc.
Because molybdenum is susceptible to corrosion in an oxidizing atmosphere, transformers must be coated with protective coatings.
