Copper busbar-a hardness (HV 70-90 vel) leh yield strength (200-300 mpa) te hi aluminum busbar thianghlim (HV 20-30 vel, yield strength 50-70 mpa) aiin a sang zawk a ni. Vibration nasa tak emaw mechanical stress (rail transit ang chi) awmna hmunah chuan copper busbar te hian deformation laka an resistance tha zawk a ni. Mahse, aluminum bar chakna chu alloying (magnesium emaw silicon emaw dah tel ang chi) hmangin nasa takin a tipung thei a ni. 6063 aluminum alloy yield strength hian 240MPa a thleng thei a, copper bar level a hnaih thei a, chutih rualin a rit lo hle bawk.
