“High specific specific gravity” hangata e bolela hore karo-karolelano ya boima ba ntho le bophahamo ba yona e kgolo, ke hore, density e hodimo. Likarolong tse fapaneng, "tekanyo e phahameng" e ka ba le meelelo le ts'ebeliso e fapaneng. Mona ke lintho tse ling tse ka amanang le "boima bo phahameng":

- Alloy e phahameng ea matla a khoheli a tungsten: Ke motsoako o thehiloeng ho tungsten o nang le palo e nyane ea Ni, Co, Mo le likarolo tse ling. E boetse e bitsoa "high-density alloy". E na le litšobotsi tse babatsehang tse kang matla a khoheli a khethehileng, matla a phahameng, matla a matla a ho monya mahlaseli a kotsi, coefficient e kholo ea mocheso oa mocheso, coefficient e nyenyane ea ho atolosa mocheso, motlakase o motle oa motlakase, ho chesehela hantle le ho sebetsa hantle. E sebelisoa haholo sebakeng sa lifofane, lifofane, sesole, ho cheka oli, lisebelisoa tsa motlakase, meriana le masimo a mang a indasteri.

- Ts'ebeliso ea li-alloys tse phahameng tsa matla a khoheli: Li-alloys tse phahameng tsa matla a khoheli li sebelisoa hangata sebakeng sa sefofane ho etsa likarolo tsa sefofane, likarolo tsa metsu le meaho ea sepakapaka; indastering ea likoloi, li ka sebelisoa ho etsa likarolo tsa enjene ea likoloi, litsamaiso tsa mariki le boima ba ho leka-lekana; ka lisebelisoa tsa bongaka Tšimo e sebelisoa haholo-holo ho radiotherapy le thepa ea meriana ea nyutlelie.

- Melemo ea li-alloys tse phahameng tsa matla a khoheli: letsoalo le phahameng, thepa e ntle ea mochini le ho hanyetsa kutu. Ka nts'etsopele ea masimo a amanang, li-alloys tse phahameng tse khethehileng tsa khoheli li lebelletsoe ho bapala karolo ea bohlokoa mafapheng a mangata.

Haeba u ka rata ho tseba haholoanyane ka Boima bo Holimo, u ka fana ka semelo kapa sebaka se ikhethileng e le hore nka araba potso ea hau hantle.
