Tungsten mesh woven
Supplier — AvekGlob Company — offers tungsten woven mesh at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Tungsten woven mesh is characterized by high-temperature strength. Tungsten has the largest tensile strength among the known metals and the minimum vapor pressure. To produce the mesh, tungsten is used with a chemical purity of 99.9%. According to the generally accepted production technology, tungsten is extracted from ores, crushed to the powder stage, and then formed and stretched into the wire, which is the basis of the woven mesh. to create a wire mesh.
Features — high fire resistance (more than 1650 ° C), extremely high heat of vaporization, good electrical and thermal conductivity, high density under mechanical loads, not changing with temperature increase, low coefficient of thermal expansion.
Urgency of application
Tungsten woven mesh is used in applications where corrosion resistance, resistance to chemically aggressive media, fire resistance, high mechanical pressures and high temperature strength are important. The most such grid is in demand in the chemical industry, in the production of ferric acids and alkalis, in mining, in the production of powerful batteries and hydrogen.
Chemical composition of mesh material
