Nimonic
Aluia maualuga le vevela
◆ Nimonic90 o loʻo i ai le malosi maualuga ma le fetolofi, lelei le faʻamaʻiina o le faʻamaʻiina ma le corrosion, ma e fetaui lelei mo tisiki turbine, lau ma faʻamau maualuga o afi afi.
◆ Nimonic91 e maualuga le malosi ma le anti-oxidation faʻatinoga i le maualuga o le vevela o le 650-1000 ° C, ma e fetaui lelei mo vaega maualuga-vevela e pei ole aero-engine blades, rocket engines, ma le malosi faaniukilia.
