Incamake yimiyoboro yicyuma
Haraheze imyaka irenga 70 kuva havumbuwe umuyoboro w'icyuma uhindagurika muri 1940. Nimbaraga zayo nyinshi, kuramba cyane, kurwanya ruswa, kurwanya ihungabana, kubaka byoroshye nibindi bintu byinshi byiza, umuyoboro wicyuma uhindagurika nicyiza cyiza kwisi ya none yo kugeza amazi na gaze mumutekano. Icyuma cyitwa Ductile, nanone cyitwa nodular iron cyangwa spheroidal grafite icyuma, kirangwa no kuba hariho spiteroidal grafite mubisubizo byatanzwe.

Ibiranga imiyoboro y'icyuma
Imiyoboro yicyuma iraboneka murwego rwa diametre kuva kuri mm 80 kugeza kuri mm 2000 kandi ikwiranye nogukwirakwiza amazi meza no gukwirakwiza (ukurikije BS EN 545) hamwe n umwanda (ukurikije BS EN 598). Imiyoboro yicyuma yoroheje iroroshye guhuza, irashobora gushyirwaho mubihe byose byikirere kandi akenshi bidakenewe gusubira inyuma. Umutekano wacyo mwinshi hamwe nubushobozi bwo kwakira ingendo zubutaka bituma biba ibikoresho byiza byumuyoboro mugari wa porogaramu.
Impamyabumenyi yumuyoboro wicyuma dushobora gutanga
Imbonerahamwe ikurikira irerekana amanota yose yibikoresho bya buri gihugu.If uri umunyamerika, noneho ushobora guhitamo 60-40-18, 65-45-12, 70-50-05 nibindi, niba ukomoka muri Ositaraliya, noneho ushobora guhitamo 400-12, 500-7, 600-3 n'ibindi

Amashanyarazi
Icyuma cyimyanda gifite imbaraga nubudahangarwa kuruta icyuma. Iyo mitungo yemerera gukoreshwa neza mubikorwa bitandukanye byinganda zikoreshwa mu nganda, zirimo imiyoboro, ibinyabiziga bitwara ibinyabiziga, ibiziga, agasanduku k'ibikoresho, amazu ya pompe, imashini zikoreshwa mu nganda zikoresha umuyaga, n'ibindi byinshi. Kuberako itavunika nkicyuma cyumuhondo, icyuma cyimyanda nacyo gifite umutekano cyo gukoresha mugukingira ingaruka, nka bollard.
