Wet Blasting Abrasive Aluminum Oxide Al2O3 98.1% 36# Tougher Roller Crushed
Tougher Roller Crushed Pink Fused Aluminum Oxide 36# for Wet Blasting Abrasive
1. Pink Fused Alumina Introduction
There is one kind of abrasive grain in alumina oxide family, which has a rose red color, is called pink fused alumina. This beautiful appearance comes from the add of chrome oxide (<0.5% Cr2O3) in the smelting process. When more chrome oxide is added (<2% Cr2O3), the materials show a deep pink color, then we get ruby fused alumina. The chrome oxide component produces an increase in toughness compared with white fused alumina, and also enhances its grinding capacity.

3. Pink Fused Alumina General advantages
1. Sharp edges, High hardness;
2. Outstanding durability;
3. High toughness;
4. Sharper and stronger than brown aluminum oxide;
5. Practically zero iron content;
6. High melting point.
4. Pink Fused Alumina Characteristics
1. High toughness, high hardness;
2. Good self-sharpening;
3. Environmental protection;
4. Strong grinding ability and Low heat generation.
5. Pink Fused Alumina Applications
Due to the feature of good toughness, high hardness and strong grinding efficiency, pink fused alumina has a higher processing efficiency than that of white fused alumina when used for processing tough materials. Pink fused alumina is suitable for manufacturing vitrified abrasives for working hardened steels and alloys with tensile strengths of over 50 kg/mm². It is also used in tool grinding, saw and knife-sharpening applications, precision grinding, profile grinding, flute grinding, tooth grinding, dry grinding of blade segments and mounted points/ wheels.
