Cabbirka caadiga ah:
Waxaan ku bixinnaa alaab qaab silig ah, silig fidsan, iyo xarig. Waxaan sidoo kale samayn karnaa agab loo habeeyey iyadoo loo eegayo codsiyada isticmaaleyaasha.
Silig dhalaalaya, la duubay, jilicsan–0.025mm~5mm
Silig cad oo lagu qaso aashitada: 1.8mm ~ 10mm
Silig Oxidized: 0.6mm ~ 10mm
Silig fidsan: dhumucdiisuna waa 0.05mm ~ 1.0mm, ballackeeduna waa 0.5mm ~ 5.0mm
Geedi socodka:
Silig: Diyaarinta walxaha → dhalaalid → dib-u-dhalaalid → foori → duubid kulul → daawaynta kulaylka → daawaynta dusha sare → sawir (rogid) → dhammaystir daawaynta kulaylka → kormeer → xirmo → bakhaar
Astaamaha alaabta:
1) Xoog aad u fiican oo ka hortagga oksaydhka iyo farsamada heerkulka sare;
2) Iska caabin sare iyo isku-darka heerkulka hooseeya ee iska caabinta;
3) Dib-u-habeyn heer sare ah iyo waxqabad sameynta;
4) Waxqabadka alxanka oo aad u fiican
