LA43Mhe mea hoʻohuihui magnesium-lithium (Mg-Li) hana kiʻekiʻe loa i hoʻomohala kūʻokoʻa ʻia e nā mea hana kūloko, e hoʻohui ana i nā pono o ke kaumaha māmā loa, ka ikaika kiʻekiʻe, ke kūpaʻa i ka pala, a me ka hiki ke hana maikaʻi loa. Ma ke ʻano he mea hoʻolālā māmā kipi, e uhaʻi ana ia i nā bottlenecks hana o nā mea hoʻohuihui magnesium kuʻuna a me nā mea hoʻohuihui alumini, a ua ʻike nui ʻia ma nā kahua kiʻekiʻe e like me ka aerospace, nā mea uila 3C, a me nā mea lapaʻau.
Me ka haʻahaʻa o ka nui e like me 1.64g/cm³ (30% māmā ma mua o nā mea hoʻohuihui alumini a me 50% māmā ma mua o ke kila), hoʻokō ʻo LA43M i ke kaulike kūpono ma waena o nā "waiwai māmā" a me nā "waiwai mechanical", e hāʻawi ana i kahi hopena mea kūpono no nā ʻoihana e ʻimi nei i ka mālama ʻana i ka ikehu, ka hoʻomaikaʻi ʻana i ka pono, a me ka hoʻoliʻiliʻi ʻana.
