Nimonic
Aluia Mahana Kiekie
◆ ʻO Nimonic90 ka ikaika tensile kiʻekiʻe a me ke kuʻekuʻe ʻana, ke kūpaʻa oxidation maikaʻi a me ka pale ʻana i ka corrosion, a he kūpono ia no nā disc turbine, nā lau a me nā mea hoʻopaʻa wela kiʻekiʻe o nā mīkini turbine.
◆ ʻO Nimonic91 ka ikaika kiʻekiʻe a me ka hana anti-oxidation ma ke kiʻekiʻe o ka mahana o 650-1000 ° C, a he kūpono ia no nā mea wela kiʻekiʻe e like me nā aero-engine blades, rocket engines, a me ka mana nuklea.
