Incamake y'imiyoboro y'icyuma ya Ductile
Hashize imyaka irenga 70 kuva aho umuyoboro w’icyuma gikozwe mu buryo bwa ductile uvumbuwe mu myaka ya 1940. Kubera imbaraga zawo nyinshi, uburebure bwawo bwinshi, kurwanya ingese, kurwanya impanuka, kubaka byoroshye n’ibindi bintu byinshi byiza, umuyoboro w’icyuma gikozwe mu buryo bwa ductile ni wo mahitamo meza mu isi ya none yo gutwara amazi na gaze mu mutekano. Icyuma gikozwe mu buryo bwa ductile, cyitwa kandi icyuma gifite utudomo cyangwa icyuma cya graphite, kirangwa no kuba hari graphite ya spheroidal mu byuma bivamo.

Ibiranga imiyoboro y'icyuma ya Ductile
Imiyoboro y'icyuma ikoreshwa mu gukaraba iboneka mu burebure kuva kuri mm 80 kugeza kuri mm 2000 kandi ikwiriye gukoreshwa mu kohereza no gukwirakwiza amazi meza (hakurikijwe BS EN 545) ndetse no mu miyoboro y'amazi mabi (hakurikijwe BS EN 598). Imiyoboro y'icyuma ikoreshwa mu gukaraba ikoreshwa mu gukaraba ikoreshwa mu gukaraba ikoreshwa mu buryo bworoshye, ishobora gushyirwa mu bihe byose by'ikirere kandi akenshi idakeneye kongerwamo amazi. Umutekano wayo mwinshi n'ubushobozi bwo kwakira imiyoboro y'ubutaka bituma iba igikoresho cyiza cyo gukoresha mu buryo butandukanye.
Ingano z'imiyoboro y'icyuma ya Ductile dushobora gutanga
Imbonerahamwe ikurikira igaragaza imiterere yose y'ibikoresho by'icyuma bikozwe muri ductile kuri buri gihugu.INiba uri Umunyamerika, ushobora guhitamo 60-40-18, 65-45-12, 70-50-05 n'ibindi, niba ukomoka muri Ositaraliya, ushobora guhitamo 400-12, 500-7, 600-3 n'ibindi.

Gukoresha icyuma gikozwe mu cyuma ...
Ibyuma bito bito bifite imbaraga n'ubushobozi bworoshye kurusha icyuma cy'umukara. Ibyo bituma gikoreshwa neza mu nganda zitandukanye, harimo imiyoboro, ibikoresho by'imodoka, amapine, amasanduku y'ibikoresho, amapompe, ibyuma bikoreshwa mu nganda zikoresha umuyaga, n'ibindi byinshi. Kubera ko kidacika nk'icyuma cy'umukara, icyuma gito bito nacyo ni cyiza gukoreshwa mu nganda zirinda ingaruka, nka za bollards.
