Loaʻa i ka alumini alumini nā mea maikaʻi o ke kaumaha māmā, ke kūpaʻa ʻana i ka corrosion, ka palahalaha maikaʻi, ka maʻalahi o ka hana ʻana i ka ʻili curved paʻakikī a me ka ikaika kiʻekiʻe, ka mea i huki i ka manaʻo o ka ʻoihana kaʻa kaʻa a puni ka honua.I nā kaʻa kaʻaahi, hoʻohana nui ʻia ke alumini alumini e like me ke ʻano o ke kino o ke kaʻa, a ʻo ka moʻolelo ka helu ma kahi o 70% o ka nui o ke kaumaha.Ua hoʻohana nui ʻia nā ʻāpana hana alumini alumini i nā kaʻa metro.
ʻO nā mea alumini i hāʻawiʻia e Xiangxin e hoʻohana nuiʻia no ke kino kaʻa o waho o ke kaʻa, ka pā hale, ka papahele, ka papa hoʻonani o loko, a me nā puka a me nā puka makani, nā noho a me nā paipu likeʻole i loko o ke kino kaʻa.Ke hoʻomaikaʻi mau nei mākou i ke kaʻina hana, hoʻomohala a hoʻohana i ka alloy hou, paʻakikī paʻakikī paʻakikī paʻakikī a me nā mea alumini kaʻa kaʻa.
