Brown Aluminium Oxide
Deskripsi Singkat:
FEATURES Brown aluminium oxide is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials. Grit size :12#-220#; Micropowder: 240#-1200#. Character 1...
FITUR
Brown aluminium oksida menyatu dan mengkristal di bawah suhu tinggi dari campuran bauksit dan bahan baku lainnya dan lainnya. Hal ini ditandai dengan kekerasan tinggi, ketangguhan yang baik dan bentuk dalam ukuran. Abrasive alat terbuat dari itu cocok untuk menggiling logam kekuatan tarik tinggi seperti: baja karbon, baja paduan tujuan umum, besi ditempa anil dan broze keras, etc.It juga dapat digunakan sebagai bahan tahan api.
Ukuran Grit: 12 # -220 #;
Micropowder: 240#-1200#.
