Tungsten and Molybdenum have the characters of high melting point, high strength at elevated temperature, low electrical resistivity, lower thermal expansion, low work function of electron emission and low vapor pressure. These characters make tungsten and molybdenum be used widely in high temperature field. AT&M is the leading company in Chinain supplying pure tungsten and molybdenum,tungsten and molybdenum alloy in the forms of tube, bar, plate, ingot,crucible and large customization products used as heating elements for high temperature furnace, smelting crucibles, cathodes and anodes,filament for lamp, thermal couple protectives heaths, porous and composite parts.
ABOUT PLANTRefractory metal andceramics plant has been developing from Refractory Alloy Research Department of CISR (Central Iron & Steel Research Institute) foundedin 1958. As one of the earliest unit engaged in refractory metal researchand production in China,over the past 50 years, more than 250 researchprojects have been done and 58 great achievements have been madeincluding 9 national inventions,40 metallurgy ministry awards and 21national patents. Now we are at the top-level in refractory metal andceramic material researching and producing within more than 300 sets ofadvanced production equipments and 20 sets of testing facilities.
