求各位大佬看看这是啥材料
图一图二是在轴上的情况,图三是敲破之后内部结构,各位大佬看一看这是啥类型的材料 目前可以确定的:1.不能与磁铁产生吸附2.拿到砂轮上面去打磨有细小火花,并且伴随一股类似塑料燃烧的焦臭味,打磨很轻松。http://tiebapic.baidu.com/forum/w%3D580/sign=385f40b196a20cf44690fed746084b0c/ec79ddc451da81cb580644fb1466d0160924313f.jpg?tbpicau=2024-03-01-05_c90d10aa6c802c809b07aeffced2ba32http://tiebapic.baidu.com/forum/w%3D580/sign=b88dc72c805c1038247ececa8210931c/339c4710b912c8fc921331fbba039245d688213f.jpg?tbpicau=2024-03-01-05_5163d3b67877cf8bf8c707e02916ec38http://tiebapic.baidu.com/forum/w%3D580/sign=3ee5fed1d72397ddd679980c6983b216/c683a4c27d1ed21b5529e9d3eb6eddc451da3f3f.jpg?tbpicau=2024-03-01-05_1498ffe9d7bb65ca130fbcf19fed45a3
