Carbon ígwè ọkpọkọ ma ọ bụ carbon ígwè ọkpọkọ na-mere nke ígwè ingot ma ọ bụ siri ike ọkpọkọ oghere site perforation, na eme ya site na-ekpo ọkụ Rolling, oyi Rolling ma ọ bụ oyi ịbịaru. Carbon ígwè ọkpọkọ na-arụ ọrụ dị mkpa na ụlọ ọrụ ọkpọkọ nke China. The akụrụngwa nke carbon ígwè anwụrụ bụ gburugburu tube oghere.
