Unwrought Sintered Tungsten Bar for Aerospace Alloys from China
Pure tungsten bars created through sintering process, supplied unwrought for melting into high-temperature aerospace superalloys. Classified under HTS 8101.94.00.00 due to being bars obtained simply by sintering without additional processing. Essential for turbine blades and rocket nozzles requiring extreme heat resistance.
