Umwirondoro wa Aluminium wabonye ibyuma bidasanzwe byo gukata ibiti bya aluminiyumu. Aluminium irakomeye kuruta ibiti, ariko ibiti nabyo bifite ibintu byihariye, ni ukuvuga ko bifite fibre nyinshi zinkwi hamwe nubukomere bukomeye, bityo rero birakenewe guca ubu bwoko bubiri bwibikoresho, neza cyane.igishushanyo cyicyuma kibonye cyuzuye bitandukanye. Umwirondoro wa aluminium wabonye icyuma ni ubwoko bwa menyo ya trapezoidal, impande ya rake ni dogere 6-10, naho impande zifata ni dogere 0; mugukata ibikoresho bya aluminiyumu, imiterere yinyo nuburyo bwo gushushanya burahuye cyane nibiranga aluminium nkibikoresho; na Saw blade yo gutema ibiti muri rusange ibumoso n amenyo yi buryo, hamwe nu mfuruka yimbere ya dogere zirenga 15, inguni ihindagurika ya dogere 5-10, hamwe nini nini yinyuma nini cyane. Gusa igishushanyo nk'iki kirashobora kwemeza ko icyuma kibonye gifite ubukana buhagije mugihe cya fibre.
