Ubwino wa Tungsten High Density Alloy
Kuchulukirachulukira kwakukulu (mpaka 65% denser kuposa lead).
Zipangizo zolimba zilipo (Tungsten yoyera, Golide, zitsulo zamagulu a platinamu) koma kugwiritsidwa ntchito kwawo kumaletsedwa ndi kupezeka, kugwirira ntchito ndi mtengo wake.
Kupereka misa pomwe kuchuluka kwa malo kuli kochepa.
Kulemera koyikirako ndikofunikira pomwe kulondola kumafunikira pakuyika misa.
Kuyika kwa kulemera muzochitika zomwe kutuluka kwa mpweya kumakhudza kwambiri.
Zida Zotentha za Tungsten Heavy Alloys
Kutentha kwakukulu kofewa.
Low matenthedwe madutsidwe ndi otsika coefficient wa kukulitsa amapatsa zinthu kukana mkulu matenthedwe kutopa.
Kukaniza kukokoloka kwabwino kwambiri kwa aluminiyamu yosungunuka.Yamphamvu pa kutentha kwakukulu ndi kukhazikika kwa kutentha kwapamwamba.
Tungsten High Density Alloy Mechanical Properties
● High Young's modulus ya elasticity.Simakwawa mukakumana ndi mphamvu zazikulu, mosiyana ndi lead.
● Ngakhale kuti ndi amphamvu, amakhalabe odukaduka ndipo savutika kusweka.
● Kuuma kosiyanasiyana kwa ma alloys nthawi zambiri ndi 20-35 Hardness HRC.
