Tube bir ah oo aan kala go 'lahayn

Tuubbada Alloy waa nooc ka mid ah tuubooyinka birta ah ee aan sinnayn, wax qabadkeedu aad ayuu uga sarreeyaa kan birta guud ee birta, sababtoo ah nooca tuubada birta ah waxay ka kooban tahay Cr badan, caabbinta heerkulkeeda sare, iska caabinta heerkulka hooseeya, waxqabadka iska caabinta daxalka ayaa aad uga fiican   kuwa kale Dhuumaha birta , sidaas darteed tuubada daawaha waxaa si weyn loogu isticmaalaa batroolka, hawada hawada, kiimikada, korontada, kuleyliyaha, militariga iyo warshadaha kale.

Codsiga:  gudaha Batroolka, Hawada sare, Kiimikada, Korontada, Kuleyliyeyaasha, Warshadaha Milatariga

Dhamaadka: Dhammaadka Cad, Dhammaadka Gariirsan, Dhammaadka dunta
