Kakaretso ea Lisebelisoa tsa ho Betla

Lisebelisoa tse sebelisoang ho betla li oela likarolong tse tharo tsa mantlha:

1. Litšepe tsa Ferrous(e nang le tšepe)

2. Litšepe tse se nang tšepe(eseng tšepe haholo-holo)

3. Li-Alloys tse Ikhethang(li-alloy tse thehiloeng ho nickel, titanium, le cobalt)

Mofuta o mong le o mong o fana ka melemo e ikhethang bakeng sa matla, ho hanyetsa mafome, katleho ea litšenyehelo, kapa ts'ebetso ea mocheso o phahameng.

Tšepe tsa Ferrous tse Sebelisoang ho Betla

1. Tšepe ea Khabone

Tšepe ea carbon ke e 'ngoe ea thepa e tloaelehileng ea ho betla ka lebaka la ho tenyetseha ha eona le ho boloka litšenyehelo hantle.
