Brown Aluminium Oxide
Description:
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...
PARS
Brown, aluminium oxide, et conflata est ex vitris in caliditas mixtisque aliis atque aliis bauxite et rudis materiae. Est propria sua princeps duritiam, bonum ROBUR in figura et magnitudine. Abrasives instrumenta idoneae evadant ad actiones molere fecerunt ex eo quod talia metalla summus tensile vires: chalybe, rem communem, mixturae ferro, annealed oboediens multum et ferrum durum broze, adhiberi potest etiam cum praefractis etc.It materiae.
