Ikirangantego Ikimenyetso kinini Umutwe wa aluminium: Ugereranije na rivet isanzwe ihumye, diameter yumutwe wa aluminium ya rivet nini cyane.Iyo umurongo uzungurutswe nigice gihuza, umurongo ufite ahantu hanini ho guhurira hamwe nubuso bukomeye bushyigikirwa, bityo bikazamura imbaraga zumuriro no kwihanganira imbaraga zo gukurura radiyo.
Umutwe munini wa aluminiyumu ukurura imisumari ukwiranye ninganda: birakwiriye gufunga ibikoresho byoroshye kandi byoroshye kandi bikarenza umwobo, kongera diameter ya brim ifite uburyo bwihariye bwo kurinda ibikoresho byoroshye.
