Cov hlau hnyav hnyav yog cov khoom tsim los ntawm kev sib xyaw ntawm cov hlau hnyav, feem ntau suav nrog cov khoom xws li hlau, npib tsib xee, tooj liab thiab titanium. Cov alloys paub txog lawv qhov siab ceev, lub zog thiab corrosion kuj, ua rau lawv muaj txiaj ntsig zoo hauv ntau hom kev lag luam. Qee qhov piv txwv ntawm cov hlau hnyav hnyav xws li steel, stainless hlau, thiab superalloys siv hauv aerospace thiab lwm yam kev siv kub. Cov alloys no feem ntau yog siv los tsim cov tshuab, cov cuab yeej thiab cov khoom siv uas yuav tsum tau muaj zog thiab kav ntev.

Tungsten tooj liab electrodeyog cov khoom sib xyaw ua los ntawm tungsten thiab tooj liab. Cov electrodes no paub txog lawv zoo heev thermal thiab hluav taws xob conductivity, siab melting point, thiab tsis kam hnav thiab corrosion. Ntxiv tungsten rau tooj liab tsub kom nws hardness, lub zog thiab kub tsis kam, ua rau nws haum rau kev thov xws li welding kuj, hluav taws xob paug machining (EDM) thiab lwm yam hluav taws xob thiab thermally conductive daim ntaub ntawv.

Tungsten tooj liab electrodes feem ntau yog siv rau hauv kev tsim cov txheej txheem xws li qhov chaw vuam, qhov projection vuam thiab seam vuam, qhov uas lawv cov thermal conductivity thiab hnav tsis kam yog qhov tseem ceeb. Tsis tas li ntawd, lawv yog siv nyob rau hauv hluav taws xob paug machining los tsim complex duab nyob rau hauv cov ntaub ntawv nyuaj.

High-density alloy yog cov khoom siv nrog ntau dua ib chav tsev ntim. Cov alloys no feem ntau yog tsim los ntawm cov hlau hnyav xws li tungsten, tantalum, lossis uranium, uas ua rau lawv qhov ntom ntom. High-density alloys muaj nuj nqis rau lawv lub peev xwm xa qhov hnyav thiab loj hauv daim ntawv compact, tso cai rau lawv siv ntau yam kev siv. Lawv feem ntau siv hauv aerospace, tiv thaiv, kev kho mob thiab kev lag luam ib puag ncig uas lawv cov khoom tshwj xeeb muaj txiaj ntsig zoo. Piv txwv li, high-density alloys yog siv rau hluav taws xob shielding, counterweights, ballast, thiab daim ntaub ntawv uas yuav tsum tau zoo thiab compact loj.
