Tungsten eriwo mu ngeri bbiri: ne . Mu mbeera eza bulijjo, kwe kugamba, ebbugumu n’okunyigirizibwa mu kisenge, -ekika kya tungsten kyoleka omubiri omunywevu-ensengekera ya kiyubiki wakati. -ekika kya tungsten, ku ludda olulala, esobola okubaawo mu mbeera ya okisigyeni yokka, era ekifo kyayo ekinywevu kikoma wansi wa diguli 630 . Waggulu w’ebbugumu lino, kijja kukyuka mu ngeri etakyukakyuka mu kika kya -.
Okugatta ku ekyo, tungsten erina ebipimo by’omubiri ebirungi ennyo, omuli density enkulu (35g/cm3), ekifo ekisaanuuka ekinene (3422℃) n’ekifo ky’okufumba (5927℃). Obukaluba bwayo nabwo buwuniikiriza nnyo, butuuka ku 5, era erina omugerageranyo gwa Poisson omutono (28). Mu kugezesebwa kw’obugumu, tungsten eraga obugumu bwa Vickers obwa 3430MPa n’obukaluba bwa Brinell obwa 2570MPa. Okugatta ku ekyo, eby’ebbugumu ebya tungsten tebiyinza kubuusibwa maaso. Ebbugumu lyayo ery’okuyungibwa liri 3kJ/mol ate ebbugumu lyayo ery’okufuumuuka liri waggulu nga 807kJ/mol.
