LA43MʻO ia ka mea hana kiʻekiʻe ultra-light magnesium-lithium (Mg-Li) alloy i hoʻomohala kūʻokoʻa e nā mea hana hale, hoʻohui i nā pono o ke kaumaha ultra-light, ikaika kiʻekiʻe, pale ʻana i ka corrosion, a me ka hana maikaʻi loa. Ma ke ʻano he mea hoʻoheheʻe māmā māmā, ua haki ʻo ia i nā bottlenecks hana o nā huila magnesium kuʻuna a me nā alumini alumini, a ʻike nui ʻia i nā kula kiʻekiʻe e like me ka aerospace, 3C electronics, a me nā mea lapaʻau.​
Me ka haʻahaʻa haʻahaʻa e like me 1.64g/cm³ (30% māmā ma mua o nā alumini alumini a me 50% māmā ma mua o ke kila), loaʻa iā LA43M ke kaulike kūpono ma waena o nā "māmā" a me nā "mea hana mīkini", e hāʻawi ana i kahi hopena waiwai kūpono no nā ʻoihana e ʻimi nei i ka mālama ʻana i ka ikehu, hoʻomaikaʻi maikaʻi, a me ka miniaturization.
