Njengoko sisazi ukuba ubushushu obunyibilikayo be-aluminiyam scrap bungaphantsi kakhulu kunobhedu, ngokunjalo nobushushu bokuphosa, ubhedu ludinga ubushushu obuphezulu ngokuphosa ukufa.
Ke ngoko sisebenzisa imathiriyeli eyahlukileyo ukwenza imifuziselo yokuphosa ukufa. Umngundo wokwenza i-ingot yobhedu unesakhono esihle sokukhusela ukushisa.
Umatshini oqhubekayo wokuphosa ingot unesantya esingena nyathelo sokulawula imotor, emva koko sinokuhlengahlengisa isantya sokuvelisa ingot ngokulula.
