Nkigice cyingenzi cyibikoresho byo kumurika hanze, urumuri rwa aluminiyumu rurakenewe kugirango umuyaga uhangane neza. Muburyo bwo gukoresha, niba uhuye nikirere kibi, nkumuyaga mwinshi, imvura nyinshi nibindi bihe bikabije, ntabwo ingaruka zumucyo zigira ingaruka gusa, ahubwo hanaterwa ibibazo byinshi byumutekano, bizabangamira ubuzima bwabantu kandi umutungo. Kubwibyo, kunoza umuyaga wumuyaga wa aluminium alloy yumucyo ningirakamaro cyane kugirango umutekano wubuzima bwabantu nibintu byabo.
