Ol Mekanikal Properti Bilong Ol Kopa Bar

Hatnes (HV klostu 70-90) na strong bilong ol kopa basbar (200-300 mpa) i winim ol basbar bilong aluminium (HV klostu 20-30, strong bilong 50-70 mpa). Long ol ples we i gat bikpela guria o hevi bilong masin (olsem tren transit), ol kopa basbar i gat gutpela strong bilong sakim senis. Tasol, strong bilong ol 'aluminum bar' inap long kamap gutpela moa sapos ol i putim 'alloy' (olsem putim 'magnesium' o 'silicon'). Strong bilong 6063 aluminium aloi inap long kamap 240MPa, klostu long mak bilong ol kopa bar, tasol em i no hevi tumas.
Long sait bilong prosesim, 'ductility' bilong ol kopa bar (elongesen reit 45%-50%) i mekim ol i isi long bendim na sutim, tasol taim ol i prosesim ol aluminium bar i go long ol kompleks seip, ol i mas tingim hevi bilong springbek. Olsem ol fleksibel kondukta, ol kebol i no inap senis long ol taim we spes i sot o ol i nidim ol dainamik koneksen, olsem ol robot join. Tasol, 'contact resistance' na 'heat dissipation capacity' bilong ol i no strong tumas winim ol 'rigid conductors'
