 Introduction of black fused alumina

 

Black aluminium oxide(lower aluminium oxide abrasive)is a new type abrasive material for polishing various metal.Black aluminium oxide abrasive is featured with high hardness,strong tenacity,good self-sharpening,better cohesisness,higher durability,less heat generated in grinding and giving the metal works high finish,less power weakened in grinding.It is mostly used in grindin and polishing stainless steel,metal works ,optical glass,bamboo or articles.And it is also the new grinding material of producing colophony grinding wheels,slice,and emery cloth.

 

 

Grit size: 16#,20#,24#30#,36#,46#,54#,60#,80#,100#,120#,150#,180#,220# 240#

 

Advantage

 

• high toughness
• high temperature resistance
• stable thermal property
• strong cutting ability
• durability
• high work efficiency.

 Application

• It is used for the bicycle, motorcycle, sewing machine, and clock parts.
• Light ornament, plastic and hardware polishing, and also applicable to the sand blasting.
• The production materials: manufacturing resin-cutting slice, edges and corners grinding and coated abrasives.
• The black corundum particle and micro powder are suitable for stainless steel work piece polishing and abrading and making the whetstone and polishing paste.
• Black corundum sand is the preferred material of the slip-prevented road and coal pits warehousing
