Ibyuma byinshi ni ubwoko bushya bwibikoresho. Nubwo yakoreshejwe cyane mu nganda za gisirikare na batiri, ikoreshwa ryayo mu zindi nganda ryatangiye, kandi abantu ntibarabyumva neza. Dore muri make incamake yibanze yibiranga ibyuma:

Bitewe nimiterere yihariye yicyuma, ifite ibintu byinshi byiza bitandukanye nibikoresho gakondo, nka:

1. Byinshih porosity: hafi yimiterere yuzuye hamwe no kunyura hejuru ya 98%. Nibikoresho byo kuyungurura, ifite umuvuduko muke nigabanuka ryinshi;
2. Ubuso bunini bwihariye: munsi yikigereranyo kimwe, gifite ubuso bunini bwihariye ugereranije nibindi bikoresho;
3. Umubyimba mwinshi hamwe nuburyo bumwe bwa pore: ububobere bugera hejuru ya 95%, aribwo buryo butatu buringaniye kandi bubonerana, kandi bufite imbaraga zicyuma, ubunini bumwe, uburemere bwibintu byoroshye, icumbi ryinshi, hamwe no kwinjiza amajwi meza, ingufu kwinjiza no gukingira amashanyarazi;
4. Ibyuma: ibyuma bifuro ifuro irashobora gukorwa muri nikel, umuringa, icyuma cyangwa ibikoresho bivanze. Substrates zitandukanye zifite ibyuma bitandukanye, nko kurinda umuriro, kutagira uburozi, nta bisigara bitonyanga, kongera gukoreshwa, gutwara ubushyuhe, nibindi, kandi bifite aho bigarukira.
5. Irashobora gusudira, gukata, kunanuka, kuzunguruka no gutunganya ubundi buryo. Muri icyo gihe, ibikoresho by'ibyuma birashobora kongera gukoreshwa, bifasha mu kurengera ibidukikije no kuzigama amafaranga.
