Melemo ea Tungsten High Density Alloy
Boima bo phahameng (ho fihla ho 65% botenya ho feta lead).
Lisebelisoa tse teteaneng li teng (Tungsten e hloekileng, Khauta, litšepe tsa sehlopha sa platinum) empa tšebeliso ea tsona e thibetsoe ke ho fumaneha, ho sebetsa le litšenyehelo.
Ho fana ka boima moo sebaka sa bophahamo se fokolang.
Boima bo tebileng bo bohlokoa moo ho hlokehang ho nepahala ha boima.
Ho beha boima ba 'mele maemong ao ho phalla ha moea ho nang le tšusumetso e kholo.
Thermal Properties ea Tungsten Heavy Alloys
Mocheso o phahameng o nolofatsang.
Mocheso o fokolang oa mocheso le coefficient e tlase ea ho atolosa e fana ka boitsebiso bo hanyetsanang le mokhathala o chesang.
Ho hanyetsa khoholeho e ntle ea soldering ho aluminium e qhibilihisitsoeng.E matla ka mocheso o phahameng o nang le botsitso bo phahameng ba mocheso.
Tungsten High Density Alloy Mechanical Properties
● High Young's modulus ea elasticity.Ha e qhekelle ha e na le matla a bohlokoa, ho fapana le lead.
● Ho sa tsotellehe matla a tsona, li lula li le lerootho ebile li sa khone ho petsoha.
● Mefuta e thata ea li-alloys ka tloaelo ke 20-35 Hardness HRC.
