Incamake y'icyuma cy'umuringa
Ibyuma bya aluminiyumu bishobora kugabanywamo: icyuma cy’ubwubatsi, gikoreshwa mu gukora ibice bya mekanike n’imiterere y’ubuhanga; icyuma cy’ibikoresho bya aluminiyumu, gikoreshwa mu gukora ibikoresho bitandukanye; icyuma cy’imikorere yihariye, gifite imiterere yihariye ya fiziki na shimi. Dukurikije uburyo butandukanye bwo gushyira mu byiciro ibikubiye mu bintu bya aluminiyumu, gishobora kugabanywamo: icyuma cy’ubwubatsi gito, gifite ibikubiye mu bintu bya aluminiyumu biri munsi ya 5%; icyuma cy’ubwubatsi (cyo hagati), ibikubiye mu bintu bya aluminiyumu ni 5-10%; icyuma cy’ubwubatsi kinini, ibikubiye mu bintu bya aluminiyumu birenga 10%. Ibyuma bya aluminiyumu bikoreshwa cyane cyane mu bihe bisaba kudashira, kudahura n’ingese, kudahura n’ubushyuhe bwinshi, kudahura n’ubushyuhe buke no kudahuza n’imbaraga.

Ubwoko bw'ibyuma
lIbyuma bikomeye cyane byo gukurura
Ku bikoresho bisaba imbaraga nyinshi zo gukurura no gukomera kurusha ibyuma bya karuboni, hari ubwoko butandukanye bw'ibyuma bifite aloyi nkeya. Ibi bishyirwa mu byiciro by'ibyuma bifite imbaraga nyinshi zo gukurura cyangwa ibyuma by'ubwubatsi n'ibyuma bikomera. Ibyuma bifite imbaraga nyinshi zo gukurura bifite inyongera zihagije zo gukurura bituma bikomera (bikoresheje kuzimya no gushyushya) hakurikijwe inyongera zabyo zo gukurura.
lIbyuma byo gukomeretsa isanduku (carburizing)
Ibyuma bikomera mu dusanduku ni itsinda ry’ibyuma bifite karuboni nkeya aho agace k’ubuso gakomeye cyane (niyo mpamvu ijambo "case hardened") gakorerwa mu gihe cyo kuvura ubushyuhe binyuze mu kwinjiza no gukwirakwiza karuboni. Agace k’ubukomere bwinshi gashyigikiwe n’agace k’ibanze kadafite ingaruka, ari ko ubukomere buke n’ubukomere bwinshi.
Ibyuma bya karuboni bisanzwe bishobora gukoreshwa mu gukomeretsa isanduku birabujijwe. Aho ibyuma bya karuboni bisanzwe bikoreshwa, kuzimya vuba bikenewe kugira ngo habeho ubukana buhagije mu isanduku bishobora gutera guhindagurika kandi imbaraga zishobora guterwa mu gice cy'imbere ni nke cyane. Ibyuma bya karuboni bisanzwe bituma uburyo bwo kuzimya buhoro buhoro bugabanuka kugira ngo bigabanye guhindagurika kandi imbaraga nyinshi zo mu gice cy'imbere zishobora guterwa.
lIbyuma bitanga nitriding
Ibyuma bikoresha nitride bishobora kugira ubukana bwinshi bw'ubuso bitewe no kwinjiza azote, iyo bishyizwe mu kirere gikoresha nitride ku bushyuhe buri hagati ya 510-530°C, nyuma yo gukomera no gushyuha.
Ibyuma biremereye bikoreshwa mu gukurura nitride ni: 4130, 4140, 4150 na 4340.
