Melemo le Mathata a Bohlokoa
Matla a 6061:
- Ho tjheseletsa ho babatsehang – ho bonolo ho MIG/TIG mme ho na le kotsi e fokolang ya ho petsoha
- Ho hanyetsa mafome hantle haholo – ho loketse ho pepesehela kantle kapa metsing
- Ho sebetsa hantle le ho bopeha ha tsona ka mokhoa o phahameng - ho bonolo ho ntša, ho koba le ho omisa bakeng sa ho qeta
- Ho hanyetsa mokhathala hantle le matla a itekanetseng ka theko e tlase
- E fumaneha haholo ka mefuta e fapaneng: li-extrusion, lakane, poleiti, tube, bareng
Mefokolo ea 6061:
- Matla a tlase a ho qetela - ha a loketse lits'ebetso tse jarang mojaro o feteletseng
- E nolofatsa ka holimo ho ~200°C, e fokotsa tšebeliso ea mocheso o phahameng
- Ho thatafala ho fokolang ha ho robeha ho feta bahlolisani ba bang ba likarolong tse teteaneng
Matla a 7075:
- Karolelano e ikhethang ea matla ho ea boima - e hlōlisana le litšepe tse ling ha e ntse e le bobebe
- Ho thatafala ho hoholo le ho hanyetsa ho tsofala - ho loketse bakeng sa ho jara ka potoloho e phahameng ea khatello
- Ho sebetsa hantle haholo ka mocheso oa T6
- E boloka thepa mochesong o ka tlase ho lefela (e sebelisoa lits'ebetsong tsa cryogenic)
Mefokolo ea 7075:
- Ho se khone ho tjheseletsa hantle – ho ka petsoha habonolo; meralo hangata e itshetlehile ka ho tjheseletsa kapa ho tlamahana
- Ho ba kotsing e kholo ea ho petsoha ha khatello ea maikutlo le mafome ntle le kalafo e nepahetseng ea mocheso kapa ho koaheloa
- Thepa e tala e turang le ts'ebetso e theko e boima haholo

Ho eketseha ha dikahare tse sebediswang hape (hona jwale ho feta 40% difekthering tse ngata) ho fokotsa sekgeo sa ditheko, ha diphetoho tse ntjha tsa kalafo ya mocheso di ntse di ntlafatsa ho hanyetsa mafome ha 7075 (batla dithempereichara tse ntseng di hlaha tsa T73/T77). Ho sa le jwalo, mefuta ya 6061 e nang le scandium e ekeditsweng e eketsa matla bakeng sa ditshebediso tsa EV.
