1. Biraha birta ah waxay tilmaamayaan birta iyo birta.Sida birta, birta doofaarka, ferroalloy, birta shubka, iwm. Birta iyo birta doofaarkuba waa alloys ku salaysan birta iyo kaarboonka oo ah curiyaha ugu muhiimsan ee lagu daray, oo si wada jir ah loogu tilmaamo birta-carbon alloys.
Birta Doofaarka waxaa loola jeedaa badeecad lagu dhalaalay macdanta birta ee foornada qaraxa, taas oo inta badan loo isticmaalo birta samaynta iyo shubista.
Qabsoon biyyaa fi lubbuu isaanii ni yaadatama, yammuu ta’u, kanneen birtaa (dareeffama) ta’uu danda’a jedhameera.
Ferroalloy waa daawaha ka kooban birta iyo Silicon, manganese, chromium, titanium iyo walxo kale.Ferroalloy waa mid ka mid ah alaabta ceeriin ee birta samaynta.Waxa loo isticmaalaa sida deoxidizer iyo walxo lagu daro birta inta lagu jiro samaynta birta.
2. Ku rid birta doofaarka ee birta-samaynta foornada birta-samaynta oo ku dhalaali si waafaqsan hab gaar ah si aad u hesho birta.Alaabooyinka birta ah waxaa ka mid ah birta wax lagu shubo, shubista joogtada ah iyo tuurista tooska ah ee shubka birta ee kala duwan.Guud ahaan, birta guud ahaan waxa loola jeedaa birta lagu rogo noocyada kala duwan ee birta.Birtu waa bir bir ah laakiin birta si sax ah uma dhigna birta birta ah.
3. Biraha aan birta ahayn, sidoo kale loo yaqaan biraha aan birta ahayn, waxay tixraacaan biraha iyo biraha aan ahayn biraha birta ah, sida copper, tin, lead, zinc, aluminium, iyo sidoo kale naxaasta, bronze, aluminium alloys iyo alwaaxyada xajinta.Intaa waxaa dheer, chromium, nickel, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, iwm ayaa sidoo kale loo isticmaalaa warshadaha.Birahaan waxaa inta badan loo isticmaalaa sida kuwa lagu daro daawaha si loo hagaajiyo sifooyinka biraha.Waxaa ka mid ah, tungsten, titanium, molybdenum, iwm. ayaa inta badan loo isticmaalaa in lagu soo saaro mindiyo.Carbide la isticmaalo.
Biraha kor ku xusan ee aan biraha ahayn waxaa loo yaqaannaa biraha warshadaha, marka lagu daro biraha qaaliga ah: platinum, gold, silver, iwm iyo biraha dhifka ah, oo ay ku jiraan uranium radioactive, radium, iwm.
