ʻO nā ʻokoʻa ma waena o ka puna lāʻau a me ka puna hao
Mea Hana
Hana ʻia nā puna lāʻau i ka lāʻau, ʻoiai ʻo nā puna metala i hana pinepine ʻia i ke kila kila, ka hui alumini a i ʻole ke kālā sterling. He ʻokoʻa loa nā mea ʻelua i ko lākou mau waiwai kino a me ke kemika. No ka laʻana, he maikaʻi ka metalaka ductility, alakaʻi uilaa me ka conductivity thermal, ʻoiai ʻoi aku ka launa maikaʻi o ka lāʻau i ke kaiapuni a olakino hoʻi, a ʻaʻole hoʻi e hua maihaumia palakika.

Kīʻaha pepa ʻaikalima me ka puna lāʻauhoʻohana nui ʻia no ka paʻa ʻana a me ka hoʻāʻo ʻana i ka hau kalima, a ʻo kona hoʻolālā e kūlike me nā ʻano ʻai o ka hau kalima. Ma waho aʻe o ka hau kalima, hoʻohana nui ʻia nā puna metala i nā hanana lawelawe meaʻai like ʻole, e like me nā sopa, nā mea ʻono a pēlā aku.
E hoʻohana i ka ʻike
ʻO kaʻano a me ke ʻanoʻOi aku ka maikaʻi o ka puna lāʻau, ʻoi aku ka like me ka ʻike o ka hui ʻana i ka hau kalima. ʻO ka puna metala, ma muli o kona conductivity thermal, hiki ke wela iki inā hoʻohana ʻia i ka wā wela. Eia kekahi, ʻaʻole e hana kemika ka puna lāʻau me ka hau kalima, ʻaʻole e hoʻopilikia i kaʻono a me ka maikaʻio ka ʻaikalima, a i ke kāwili ʻana i ka ʻaikalima, ʻaʻole ia e hoʻoili i ka wela e like me ka wikiwiki o ka puna metala, no laila e heheʻe koke ka ʻaikalima.
