Ukoreshwa cyane mu gukora insinga, insinga, uburoso bw'amashanyarazi, n'umuringa ukoreshwa mu gutwika amashanyarazi, n'ibindi. Ni umusaruro mwiza.

Uburyo umuringa utwara amashanyarazi n'ubushyuhe ni ubwa kabiri nyuma ya feza, kandi ukoreshwa cyane mu gukora ibikoresho by'amashanyarazi n'ubushyuhe. Umuringa ufite ubushobozi bwo kurwanya ingese mu kirere, mu mazi yo mu nyanja ndetse no mu bintu bimwe na bimwe bitangiza ogisijeni (aside hidrokloriki, aside sulfuriki ivanze), alkali, umuti w'umunyu n'ibindi bintu bitandukanye bya aside organic (aside asetiki, aside citric), kandi ukoreshwa mu nganda z'imiti. Byongeye kandi, umuringa ufite ubushobozi bwo gusudira neza, kandi ushobora gutunganywa mu bicuruzwa bitandukanye byarangiye neza n'ibicuruzwa byarangiye binyuze mu gutunganya ibintu bikonje na thermoplastic. Mu myaka ya 1970, umusaruro w'umuringa utukura warenze umusaruro wose w'ibindi bikoresho byose by'umuringa.
