Molybdenum has high-temperature strength, good conduction, thermal conductivity, and low thermal expansion coefficient, so the molybdenum rod products are widely used in the high-temperature furnace as a heating body, structural parts, etc. Molybdenum rods are often used in rare earth smelting and glass smelting industries. In addition, molybdenum and its alloy bars are also made of various small molybdenum crucibles, molybdenum ion implantation parts, molybdenum electric light source product parts, and molybdenum mold parts.

Molybdenum based alloy is a non-ferrous alloy which is composed of other lanthanum, zirconium, titanium, niobium, and rhenium. Among them, TZM alloy effectively improves the mechanical properties of high temperature and is widely used in the manufacture of high-temperature tools, molds, and various structural parts. The molybdenum lanthanum alloy made from pure molybdenum oxide is also called high-temperature molybdenum in the industry, which effectively improves the recrystallization temperature of molybdenum. It also reduces the deformation of the product within a certain temperature range and improves the service life.

Molybdenum rod and molybdenum alloy bar products have the following kinds.

Sintering molybdenum rods

Molybdenum bars are usually forged to increase density and improve tissue structure. However, there is no forging process for the molybdenum rod or molybdenum block products with a diameter of more than 120 mm and single weight and only sintered products are provided. The surface of the sintered molybdenum rod is silvery gray.

Forging molybdenum rods

The forging of molybdenum bars is commonly referred to as the black molybdenum rod because of the presence of a layer of oxide on its surface. The forging of the molybdenum rod surface allows for a slight oxidation film and hammer marks. The density and structure of the forged molybdenum rod are directly related to the deformation of the molybdenum bar during forging.

Rotary swaging molybdenum rod

The rotary forging molybdenum rod is also called black molybdenum rod. It is usually forged to a certain diameter and is processed through a rotary forging machine.

Polished molybdenum bars

Molybdenum bars and TZM bars and high-temperature molybdenum bars are used for the implantation of ion implantation parts as well as the blanks for the manufacture of high-temperature tools, molds, and various structural parts. For the purpose of use, the production of molybdenum bars has higher requirements on the physical properties of materials such as density, homogeneity and mechanical strength. Therefore, the requirement of the forging process is beyond the requirement of ordinary die forging.

Molybdenum tubes

Molybdenum tubes are used in a high-temperature environment for air conduction or liquid conduction, and it is also used in thermocouple sleeve. Molybdenum tube is made of forged molybdenum rod by machining. For a molybdenum tube with a length of more than 100 mm, the inner diameter is usually more than 8 mm.

Molybdenum electrode rods

Molybdenum electrode is made from molybdenum rod and mainly used in glass melting and rare earth smelting industry.
