He mea hanga ā mātou taputapu tapahi pākahiko ki te maitai tungsten tino pakeke, ā, he mea hanga motuhake mō te tapahi tika i ngā wahi pou me ngā wehewehe pākahiko lithium. Ka puta he tapahi maeneene, kāore he kohao i roto i ō rātou mata koi, ātete ki te pakaru, ka whakakorea ngā kohao me te puehu, ka whakarite kia pumau te mahi pākahiko. Ka taea te whakamahi i te taputapu tapahi whakawhiti me tētahi pupuri taputapu e ōrite ana mō te ngāwari o te tāutanga me te mahi pumau, e whai hua whānuitia ana mō ngā tukanga tapahi me te hanga i roto i te hanga pākahiko lithium.
