Tungsten High Density Alloy Advantages
High ceev (txog 65% denser dua Lead).
Cov ntaub ntawv denser muaj nyob (ntshiab Tungsten, Kub, platinum pab pawg hlau) tab sis lawv siv yog txwv los ntawm kev muaj, ua haujlwm thiab nqi.
Muab huab hwm coj qhov chaw ntim tsawg.
Concentrated hnyav qhov tseem ceeb qhov tseeb yog yuav tsum tau nyob rau hauv qhov chaw ntawm loj.
Qhov chaw ntawm qhov hnyav nyob rau hauv cov xwm txheej uas airflow muaj kev cuam tshuam loj heev.
Thermal Properties ntawm Tungsten Heavy Alloys
Siab softening kub.
Tsawg thermal conductivity thiab tsis tshua muaj coefficient ntawm expansion muab cov khoom muaj zog tiv thaiv thermal qaug zog.
Zoo heev soldering yaig tsis kam rau molten aluminium.Muaj zog ntawm qhov kub thiab txias nrog siab thermal stability.
Tungsten High Density Alloy Mechanical Properties
● High Young lub modulus ntawm elasticity.Tsis nkag siab thaum ntsib cov rog tseem ceeb, tsis zoo li Lead.
● Txawm tias lawv lub zog, lawv nyob twj ywm thiab tiv taus tawg.
● Lub hardness ntau ntawm cov alloys feem ntau yog 20-35 Hardness HRC.
