Electrocorundum normal 25A Properites
Electrocorundum normal 25A is an electrofused aluminum oxide with high hardness. The quality complied with GOST 3647-80 & ISO 6344 standards. Different from Electrocorundum normal 14A, 25A is a higher Al2O3 percentage more than 99% in White color.
The Properties of Electrocorundum Normal 25A:
The abrasive edge of Electrocorundum 25A is sharp with high self-sharpening. That can get aggressive grinding and abrasion.
The Fusing process is at a temperature of 2400 degrees. The thoroughly fusing process makes the most of the alumina of α-Al2O3. That is the key element to get high hardness, refractory, and grinding ability.
High thermal resistance. It can resist high temperature above 1850 degrees. As a result, it can not only wear the grinding heat but also can work as high thermal ceramics.
Uniform particle size, Both Electrocorundum Normal 25A macrogrit and microgrit particle range are seriously controlled by GOST standard. Thus, it can process a uniform polishing surface.
Neutral PH value and contaminant free.
Low oil absorption rate.
