Molybdenum mesh netting

Molybdenum mesh netting

Supplier — AvekGlob company — offers molybdenum braided net at a reasonable price from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Molybdenum braided mesh is characterized by high-temperature strength and heat resistance. They are characterized by the stability of the dimensions of the cells, which do not depend on the oscillations of external temperatures and pressures, while the structure of the grid does not change. Due to these properties, the molybdenum mesh is usually used in heating elements and high temperature furnaces as a load-bearing structure, a mesh protective or filter media. However, to ensure the necessary durability, the product must be operated in a vacuum or in a reducing atmosphere. Therefore, molybdenum braided nets are often found in the equipment of the chemical industry.

Features of molybdenum mesh: high strength at high temperatures, low vapor pressure, limited thermal expansion, excellent thermal conductivity, low electrical resistance.

Urgency of application

Molybdenum braided mesh is used in applications where corrosion resistance, flue gas resistance, fire resistance, high mechanical pressures and temperature resistance are important. Such grids are used in automotive components, building parts, oil and gas pipelines, as well as chemical processing lines for materials.

In electrical engineering this material is used as shielding elements of heating resistance furnaces and supporting bodies of filaments of powerful incandescent lamps. At higher requirements for wear resistance, woven meshes of molybdenum alloys with iron and / or nickel-permalloy are used.

Chemical composition of mesh material

For the production of nets of various accuracy of domestic production, the wire from molybdenum is usually used in accordance with GOST 26266−87:

Molybdenum brand Mass fraction of molybdenum,%, not less than Mass fraction of additive,% Mass fraction of the sum of impurities,%, not more than
MCH 99.96 - 0.04
MK 99.92 Silicon 0.019… 0.04 0.04
MRN 99.92 - 0.08

Note. The amount of impurities includes elements: calcium, magnesium, silicon, nickel, iron, aluminum, if they are not additives.
