Brown Aluminium Oksyde
Koarte beskriuwing:
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...
FEATURES
Brún aluminium okside wurdt fergroeid en útkristallisearre ûnder hege temperatuer út in mingsel fan derby en oare en oare grûnstoffen. It wurdt karakterisearre troch syn hege hurdens, goede hurdens en foarm yn grutte. Abrasives ark makken dêrfan binne geskikt foar it meallen metalen fan de hege-tensile krêft lykas: koalstof stiel, algemien-doel alloy stielen, annealed malleable izer en hurde broze, etc.It ek kin brûkt wurde as stege materialen.
Grit size: 12 # -220 #;
Micropowder: 240#-1200#.
