Molybdenum Mesh

Molybdenum Mesh is made of high-purity molybdenum or molybdenum alloy wire, possessing similar properties to tungsten in many conditions. It has a series of excellent properties such as great strength at high temperatures, small vapor pressure, limited thermal expansion, outstanding heat conductivity, and low electric resistivity. It is commonly used in heating elements and high-temperature furnaces as structure support, mesh protectors, or filter media. HM can supply customized solutions according to specific requirements at competitive prices.

Molybdenum Mesh Applications

High-Temperature Environment: Molybdenum mesh is commonly used in high-temperature furnaces and other high-temperature equipment.
Petroleum and Chemical: Due to its acid- alkali-resistant and corrosion-resistant properties, molybdenum mesh is often used for filtration and screening in the petrochemical industry.
Mechanical Manufacturing: Molybdenum mesh is used to manufacture certain specialized components due to its high strength and wear resistance.
Food and Medicine: Due to its non-toxic and corrosion-resistant properties, molybdenum mesh is also used in the food and pharmaceutical industries.
Aerospace: Molybdenum mesh is used as a key component in producing large deployable mesh parabolic antennas due to its high strength and electrical conductivity.

Molybdenum Mesh Packaging

The Molybdenum Mesh is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
