ʻOi aku ka paʻakikī (HV ma kahi o 70-90) a me ka ikaika hoʻohua (200-300 mpa) o nā pahu keleawe ma mua o nā pahu pahu alumini maʻemaʻe (HV ma kahi o 20-30, 50-70 mpa ka ikaika). I nā kaiapuni me ka haʻalulu nui a i ʻole ke koʻikoʻi mechanical (e like me ke kaʻa kaʻaahi), ʻoi aku ka maikaʻi o ka pale ʻana o nā busbar keleawe i ka deformation. Eia naʻe, hiki ke hoʻonui nui ʻia ka ikaika o nā pahu alumini ma o ka hoʻohui ʻana (e like me ka hoʻohui ʻana i ka magnesium a i ʻole ke silika). ʻO ka ikaika o ka 6063 alumini alumini hiki ke hiki i ka 240MPa, e hoʻokokoke ana i ke kiʻekiʻe o nā pahu keleawe, me ka mālama ʻana i kahi kaumaha māmā.
Ma ke ʻano o ka hana ʻana, ʻo ka ductility o nā pahu keleawe (elongation rate 45% -50%) e maʻalahi iā lākou e kulou a kuʻi, akā i ka wā e hana ai i nā pahu alumini i nā ʻano paʻakikī, pono e noʻonoʻo ʻia ka pilikia o ka springback. Ma ke ʻano he mea hoʻokele maʻalahi, ʻaʻole hiki ke hoʻololi ʻia nā kaula i nā hiʻohiʻona kahi i kaupalena ʻia ai ka wahi a i ʻole nā pili ikaika e pono ai, e like me nā hui robot. Eia nō naʻe, ʻoi aku ka nāwaliwali o kā lākou hoʻopili ʻana a me ka hiki ke hoʻoheheʻe wela ma mua o nā mea hoʻokele paʻa.
