Brown Aluminium Oxide
Kort beskrywing:
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...
KENMERKE
Brown aluminiumoksied word saamgesmelt en gekristalliseer onder hoë temperatuur van 'n mengsel van bauxiet en ander en ander grondstowwe. Dit word gekenmerk deur sy hoë hardheid, goeie taaiheid en vorm in grootte. Skuur gereedskap gemaak van dit is geskik vir die maal metale van 'n hoë-treksterkte soos: koolstof staal, algemene doel aluminium staal, uitgegloei smeebaar yster en hard broze, etc.It kan ook gebruik word as 'n vuurvaste materiaal.
K grootte: 12 # -220 #;
Micropowder: 240#-1200#.
