Brown Alumiiniumoksiid
Lühike kirjeldus:
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...
OMADUSED
Brown alumiiniumoksiidi on kondenseerunud ja kristalliseerunud kõrgetel temperatuuridel segust boksiidi ja muud ja muud toorainet. Seda iseloomustab selle suure kõvaduse, hea sitkus ja kuju suurusega. Abrasiivid tööriistu valmistatud see sobivad lihvimine metall suure tõmbetugevusega näiteks: süsinikterasest, üldotstarbeline legeerterasest, lõõmutatud Sepised ja kõvade Broze, etc.It ka saab kasutada tulekindlate materjalidega.
Grit suurus: 12 # -220 #;
Micropowder: 240#-1200#.
