ʻO ka XBD-2431 ka motika metala makamae he kaʻa i hana ʻia me nā mea metala makamae, e pili ana i nā motika e hoʻohana ana i nā mea metala makamae e like me ke kālā, platinum, a me ke gula e hana i nā pulupulu a i ʻole nā mea nui ʻē aʻe. ʻO kēia mau mea metala makamae he conductivity uila maikaʻi, ke kūpaʻa a me ka pale ʻana i ka corrosion, no laila hoʻohana nui ʻia lākou i ka hana kaʻa.
He waiwai hoʻohana koʻikoʻi kā mākou mau mīkini metala makamae Sinbad i kekahi mau kahua kūikawā. Ma muli o ka maikaʻi o ka conductivity uila a me ke kūpaʻa ʻana o nā mea metala makamae, ua hoʻohana nui ʻia nā mīkini metala makamae i nā kula e koi ana i ka hana kaʻa kiʻekiʻe, e like me ka aerospace, ka pale aupuni a me nā ʻoihana koa. Loaʻa i kēia mau māla nā koi kiʻekiʻe e pili ana i ka hilinaʻi, kūpaʻa a me ka lōʻihi o nā kaʻa, a hiki i nā mea metala makamae ke hoʻokō i kēia mau koi.
