Oxid de aluminiu maro

Scurta descriere:

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...

    CARACTERISTICI

    oxid de aluminiu Brown este topit și se cristalizează sub temperatură ridicată dintr-un amestec de bauxită și alte și alte materii prime. Acesta este caracterizat prin duritate ridicată, tenacitate bună și forma în dimensiune. Abrazive instrumente din ea sunt potrivite pentru măcinarea metalelor cu rezistență mare la tracțiune, cum ar fi: oțel carbon, oțel aliat cu scop general, fier maleabil recoaptă și BROZE greu, etc.It pot fi utilizate ca materiale refractare.

    Granulatie: 12 # # -220;
    Micropowder: 240#-1200#.
