Tsawg resistivity ntawm tooj liab tub ntxhais: lub resistivity ntawm txhuas core yog hais txog 1.68 lub sij hawm siab tshaj ntawm cov tub ntxhais tooj liab;
Cov tub ntxhais tooj liab muaj ductility zoo;
High strength of copper core: allowable stress at room temperature, copper can reach 20, aluminum is 15.6kgt/mm2;
Copper core qaug zog tiv thaiv: aluminium yog ib qho yooj yim rau tawg tom qab rov khoov, tab sis tooj liab tsis yooj yim;
Cov tub ntxhais tooj liab muaj kev ruaj ntseg zoo thiab kev tiv thaiv corrosion: cov tub ntxhais tooj liab yog resistant rau oxidation thiab corrosion, thaum lub txhuas core yog susceptible oxidation thiab corrosion.
