ABOUT PRODUCT Specification: Diameter(mm): 30-50min,450-550max, Wall thickness(mm): 8-10min, 15-30max. Length(mm): <1200mmTungsten 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 PLANT Refractory metal and ceramics plant has been developing from Refractory Alloy Research Department of CISR (Central Iron & Steel Research Institute) founded in 1958. As one of the earliest unit engaged in refractory metal research and production in China,over the past 50years, more than 250 research projects have been done and 58 great achievements have been made including 9 national inventions,40 metallurgy ministry awards and 21 national patents. Now we are at the top-level in refractory metal and ceramic material researching and producing within more than 300 sets of advanced production equipments and 20 sets of testing facilities. AT&M Refractory Plant is ISO9001:2000 certified.ABOUT EQUIPMENTS The main equipments include: Φ1250×2300mm cold and hot isostatic pressing achine; Tmax=2,400 high temperature sintering furnaces;large-scale vacuum sinteringfurnaces;Large infiltration furnaces for metal and metal ceramic composites;Tmax=2000 high temperature tensile strength tester;Ultrasonic crack detector; Laser thermal conductivity tester; laser powder particle size tester.ANNUAL CAPACITY The annual production capacity is more than 600 tons of tungsten and molybdenum products.
