Dai magri busbar ni a ngang kang ai (HV 70-90 daram) hte n-gun (200-300 mpa) gaw, san seng ai aluminum busbar ni hta grau kaja ai (HV 20-30 daram, n-gun 50-70 mpa). Grai kaba ai n-gun (sh) jak rung n-gun (rail transit zawn re ai) nga ai grup yin ni hta, magri busbar ni gaw n-gun n rawng ai hpe grau hkam sharang lu ai. Raitim, aluminum bar ni a n-gun hpe alloying (magnesium (sh) silicon bang ai zawn re ai) hku nna grai jat wa shangun lu ai. 6063 aluminum alloy a yield strength gaw 240MPa du hkra rai nna, magri bar ni a madang de sit sa wa lu ai, dai sha n-ga, n-gun n law ai hpe mung naw tawn da lu ai.
Hpaga lam hta, magri mang n-gang ni a ductility (elongation rate 45%-50%) a majaw, shinggrup nna gap na matu loi ai, raitim, aluminum n-gang ni hpe n-gun ja ai hkrang ni de galaw ai shaloi, springback ngu ai lam hpe myit yu ra ai. Flexible conductor ni hku nna, shara n law ai (sh) n-gun ja ai matut mahkai lam ni ra ai, robot joint zawn re ai masa ni hta cable ni hpe galai shai n mai ai. Raitim, shanhte a matut mahkai ai lam hpe ninghkap lu ai atsam hte katsi ai hpe shapraw kau lu ai atsam gaw rigid conductor ni hta grau n-gun kya ai.
