ʻO ka Uea Oven Uila ke ʻano o ka uea uila kūʻē kiʻekiʻe. Kū'ē ka uea i ke kahe o ka uila, a hoʻololi i ka ikehu uila i ka wela.
ʻO ka noi no ka uea kū'ē e pili ana i nā mea pale, nā mea hoʻomehana, nā mea hoʻomehana uila, nā umu uila, nā mea hoʻoheheʻe, a me nā mea hou aku.
ʻO Nichrome, kahi huila non-magnetic o ka nickel a me ka chromium, hoʻohana mau ʻia e hana i ka uea kūʻē no ka mea he kiʻekiʻe ke kūpaʻa a me ke kūpaʻa ʻana i ka oxidation ma nā wela kiʻekiʻe. Ke hoʻohana ʻia ma ke ʻano he mea hoʻomehana, ʻeha maʻamau ka uea kūʻē i nā coils. ʻO kekahi pilikia i ka hoʻohana ʻana i ka Uea Uila Uila, ʻaʻole e paʻa ka solder uila maʻamau iā ia, no laila pono e hana ʻia nā pilina i ka mana uila me nā ala ʻē aʻe e like me nā mea hoʻopili crimp a i ʻole nā hopena wili.
ʻO FeCrAl, kahi ʻohana o ka hao-chromium-aluminum alloys i hoʻohana ʻia i kahi ākea ākea a me nā noi wela kiʻekiʻe e hoʻohana ʻia ma ke ʻano o nā uea kūʻē.
