(Ikibazo cya gatatu: 2A01 aluminiyumu)

Mu nganda zindege, imirongo nikintu cyingenzi gikoreshwa muguhuza ibice bitandukanye byindege. Bakeneye kugira urwego runaka rwimbaraga kugirango indege ihagaze neza kandi bashobore guhangana nibidukikije bitandukanye byindege.

2A01 ya aluminiyumu, kubera imiterere yayo, irakwiriye gukora indege zubatse indege zuburebure buringaniye hamwe nubushyuhe bwo gukora butarenze dogere 100. Ikoreshwa nyuma yo kuvura igisubizo no gusaza bisanzwe, bitagabanijwe nigihe cyo guhagarara. Diameter y'insinga yatanzwe muri rusange iri hagati ya 1,6-10mm, ikaba ari umusemburo wa kera wagaragaye muri 1920. Kugeza ubu, hari porogaramu nkeya muburyo bushya, ariko ziracyakoreshwa mubyogajuru bito bya gisivili.
