Nyob rau hauv xov tooj uas tsis-ferrous yog ib lub npe siv co. Thaajmaum muab thiab co cov-ferrous thiab cov alloys kuj raug txhua yam, siv, electronics, aerospace, nuclear zog thiab lwm qhov chaw indispensable yam ntaub ntawv thiab tej ntaub ntawv.
Nyob rau hauv daim ntaub ntawv uas ua tau, feem ntau tsis-ferrous co yog muab faib ua 5 pawg:
Co lub teeb
Ceev yog qhov tsawg tshaj 4,500 kilograms/nyhav ' meter ' (0.53~4.5G/cm3), xws li cov calcium uas, magnesium, potassium, sodium, calcium, strontium, barium, etc.
Heavy hlau
Ceev tshaj 4,500 kilograms/nyhav ' meter ' (4.5G / cm3), xws li tooj, npib tsib xee, cobalt, txhuas, zinc, yajthem, antimony, bismuth, cadmium, muaj mercury, etc.
Zoo zoo nkauj tshooj
Nqi kim hlau zoo tib yam, uas tsis muaj crustal abundances, thiab tsis yooj yim, ruaj khov tshuaj zog, xws li kub, nyiaj thiab platinum pawg co.
