ʻO nā mea o nā paipu keleawe keleawe ka mea me ka ikaika tensile maikaʻi, ka ikaika luhi, ka paʻakikī kūpono, ka elongation haʻahaʻa a me ka coefficient conductivity wela. ʻO ka hopena, ʻae ʻia nā mea e like me ka phosphorous deoxidize copper （DHP）,CUAG，CR-ZR-CU e nā mea hoʻohana o nā ʻāina āpau. Nā uhi: He haʻahaʻa ka paʻakikī o ke keleawe e alakaʻi i ka waiwai anti-abrasive haʻahaʻa. No laila, ʻo ka ʻāpana ma ka ʻaoʻao haʻahaʻa o nā poni, kahi e piʻi nui ai ke koʻikoʻi ma muli o nā pūpū, e ʻoi aku ka paʻakikī. No ka hoʻonui ʻana i ka manawa ola o nā poʻi keleawe, pono ʻia ka Uniform mold interior surface plating me ka paʻakikī kūpono. ʻAʻole hoʻohana ʻia ka hapa nui o nā paipu keleawe keleawe no ka hoʻolei ʻana i ka billet liʻiliʻi i kekahi ʻōnaehana hoʻolei ʻana i kahi kākoʻo kahawai hoʻolei paʻa, no laila ua maʻalahi lākou e ʻaʻahu. Hoʻohana mākou i ka chrome plating paʻakikī e hoʻonui i ke ola o nā paipu mold. E hoʻomaluʻia ka mānoanoa plating i ka laulā maikaʻi loa. E pili ana i ka uhi ʻana o nā pā keleawe keleawe, e pili ana i kā mākou mau makahiki o ka ʻike, hiki iā mākou ke hāʻawi i ka uhi Cr, Ni-Cr coating, Ni-Fe coating e hoʻokō i ka makemake o nā mea kūʻai aku ma ka home a ma waho.
