Puanu kila EN45
ʻO EN45 he kila puna manganese. ʻO ia hoʻi, he kila ia me ka nui o ke kalapona kiʻekiʻe, nā ʻāpana manganese e pili ana i nā waiwai o ka metala, a hoʻohana mau ʻia ia no nā pūnāwai (e like me nā puna wai hoʻomaha ma nā kaʻa kahiko). He kūpono ia no ka hoʻopaʻa ʻana i ka ʻaila. Ke hoʻohana ʻia i loko o ka ʻaila paʻakikī a me ke ʻano wela ʻo EN45 hāʻawi i nā ʻano punawai maikaʻi loa. Hoʻohana pinepine ʻia ʻo EN45 i nā ʻoihana kaʻa no ka hana ʻana a me ka hoʻoponopono ʻana i nā puna lau.
Puanu kila EN47
He kūpono ʻo EN47 no ka hoʻopaʻa ʻana i ka ʻaila a me ka hoʻomaʻamaʻa. Ke hoʻohana ʻia i loko o ka ʻaila paʻakikī a me ke ʻano wela EN47 pūnāwai kila e hui pū i nā hiʻohiʻona puna me ka ʻaʻahu maikaʻi a me ke kūpaʻa abrasion. Ke hāʻawi aku nei ʻo EN47 i ka paʻakikī a me ke kūpaʻa haʻalulu maikaʻi e lilo ia i mea kila puna wai kūpono no nā ʻāpana i ʻike ʻia i ke koʻikoʻi, ka haʻalulu, a me ka haʻalulu. He kūpono no nā noi e koi ana i ka ikaika tensile kiʻekiʻe a me ka paʻakikī. ʻO nā mea hoʻohana maʻamau, ʻo ia nā crankshafts, nā puʻupuʻu hoʻokele, nā gears, spindles, a me nā pamu.
Hoʻohālikelike ʻia nā papa a pau o ka lāʻau hao puna
