Nws tuaj yeem ua tau zoo ua rau cov txheej txheem thiab cov khoom me me (xws li cov hniav nyiaj hniav kub (xws li cov pob-hluav taws xob) nrog cov khoom siv hluav taws xob tsawg dua, ua kom cov hlau tsis yeem, du nto thiab tsis muaj kev ua dua tshiab. Nws yog qhov tsim nyog tshwj xeeb rau cov hlau siab-tus nqi hlau.

Muaj cov muaj txiaj ntsig me ntawm Dazao: Kub, nyiaj, platinum, palladium thiab lwm yam.
Kub
Ductility siab thiab ntsuas melting point ua kom yooj yim rau nws cov khoom siv precision seem, tab sis cov khoom siv zoo tau tom qab sintering kom ruaj khov.
