Zoo toughness, ntsia thawv tsis kam thiab sab nraud cuam tshuam.Nws tuaj yeem txiav arbitrarily raws li qhov sib txawv engineering tsim thiab cov txheej txheem yuav tsum tau, khoov thiab hloov cov duab, yuav tsis nkig, tsis yooj yim rau khawb, thiab resistant Acid-base corrosion thiab dej vapor corrosion, thermal conductivity, nws tus kheej-extinguishing nplaim retardant. B1 qib tus qauv, tuaj yeem ncua kev sib kis ntawm hluav taws.
