Birta birta ah ee birta ah ee birta ah waa walxaha jilicsan ee steels-ka. Waxaa loo adeegsan karaa in lagu beddelo macdanta kala duwan ee macdanta iyo kuwa aan caadiga ahayn, sida alumina, silicon Carbide, rooti Quartz, Clars Glock, iwm.
Birta birta ah ee birta ah ayaa inta badan loo isticmaalaa nadiifinta dusha sare, rinjiga ka saarida iyo daminta biraha aan furfuran iyo alaabada birta aan la isku qurxin, oo ay si gaar ah ugu habboon tahay is-xakameynta dusha sare ka hor daboolka. Marka la barbardhigo nabaad-guurka aan caadiga ahayn ee birta ah, birta bir-qaadka birta ah ee birta lagu yareeyo si loo yareeyo kharashaadka iyo qiiqa hawada iyo hagaajinta jawiga shaqada.
Birta birta ah ee birta ah ayaa leh nolol dheer iyo wax qabad aad u sareysa, fududeynta geedi socodka qarxinta, oo lagu badbaadinayo tayada qaraxyada, oo lagu guuleysto tayo-uruurinta iyo muuqaalka.
