Product Features
1.Balanced Hardness and Toughness
Abrasive grains are not easy to break during grinding, ensuring sharp cutting while reducing wear, achieving a good balance between cutting efficiency and tool life.
2.Excellent Self-Sharpening
Grains micro-fracture naturally during use, exposing new sharp cutting edges, avoiding efficiency loss caused by dulling, reducing tool changes and lowering processing costs.
3.Stable Grinding Performance
Dense crystal structure, uniform chemical composition, free of impurities. Not prone to causing cracks during grinding, ensuring flat and smooth machined surfaces with less scratching or burning.
4.Good Corrosion and Heat Resistance
High chemical stability after forming, resistant to high temperatures during grinding, not easy to oxidize or degrade. Performs well in humid and mildly corrosive environments, adaptable to various working conditions.
5.Outstanding Cost Performance
Reasonable price, lower cost than white fused alumina, better grinding effect than brown fused alumina, making it the preferred abrasive for most general grinding applications.
Applications
1.Bonded Abrasives
Mainly used for ceramic grinding wheels, resin wheels, grinding heads, oilstones, etc. Suitable for high-speed and general grinding, especially for applications requiring high toughness, such as grinding bearings, gears, shafts.
2.Coated Abrasives
Used for abrasive belts, sandpaper, emery cloth, etc. Widely applied in machinery, hardware, auto parts manufacturing for surface treatment of plates, tubes and profiles.
3.Precision Machining
Suitable for semi-finish and finish grinding of precision parts, ensuring high dimensional accuracy and surface finish to meet strict requirements, especially for metals with moderate hardness and good toughness.
4.Other Applications
Used for sandblasting and surface roughening; as an abrasive component in high-grade grinding fluids to reduce dust and improve efficiency; also used in refractories and wear-resistant materials to enhance hardness and wear resistance.

FAQ
Q: Does it have better wear resistance than white alumina?
A: Yes. The crystal structure modified by chromium oxide provides higher fracture toughness, resulting in longer service life in abrasive conditions.
Q: Can it be used for grinding stainless steel?
A: Yes. Its high toughness and resistance to heat make it ideal for grinding hard alloys like stainless steel without causing burning or deformation.
Q: How does it differ from white fused alumina?
A: While both are high-purity alumina, pink fused alumina offers superior toughness and thermal stability due to the chromium addition, making it less brittle.
Q: Do you provide customized chemical compositions?
A: Yes. We can adjust Al₂O₃ and Cr₂O₃ ratios and control impurity levels strictly according to your specific technical requirements.
