Thaum lub sij hawm kub khiav pwm txheej txheem, cov yas yaj kub yog tswj kom raug nyob rau hauv qhov kev khiav hauj lwm. Cov yas tuaj yeem ntws mus rau hauv cov kab noj hniav hauv lub xeev zoo dua, ua rau muaj qhov zoo sib xws. Cov kub khiav molding qhov chaw muaj qhov rooj zoo zoo, tsis tshua muaj kev ntxhov siab tom qab demolishing, thiab me me deformation ntawm qhov chaw. Yog li ntau cov khoom zoo ntawm kev ua lag luam yog tsim los ntawm kub khiav pwm.

Txij li thaum tungsten-molybdenum thiab nws cov ntaub ntawv alloy muaj cov thermal conductivity siab, siab kub lub zog, creep tsis kam, hnav tsis kam, thiab siab corrosion kuj, lawv yog cov khoom tsim nyog rau kev ua kub khiav nozzles hauv kev txhaj tshuaj molding khoom xws li txhaj tshuaj molding tshuab.
