Uas muaj zog, tooj liab dig muag rivet los yog tooj dag dig muag rivet?
Ntshiab tooj liab, tseem hu ua liab tooj liab, muaj qhov ntom ntawm (7.83g / cm3) thiab melting point ntawm 1083 degrees. Nws yog non-magnetic. Nws muaj zoo conductivity, thermal conductivity, corrosion kuj thiab toughness.
Qhov ntom ntawm tooj dag (8.93g / cm3) yog siv rau hauv ob sab phlu nrog cov neeg kho tshuab bearing hav txwv yeem, uas yog hnav-resistant.
Qhov ntom ntawm "tooj dag" yog siab dua li ntawm tooj liab liab, thiab "tooj dag" yog tawv nrog zoo rigidity.
