Frequently Asked Questions
What is a Calcined Aluminium Oxide Flap Disc?
A Calcined Aluminium Oxide Flap Disc is made from heat-treated alumina abrasive grains. The heating process enhances both hardness and toughness, giving it better durability and cutting performance than standard aluminium oxide discs.
What are the advantages of using calcined aluminium oxide?
It offers improved sharpness, cooler grinding, longer lifespan, and more consistent performance — making it ideal for users who need stable and efficient grinding results.
What materials can Calcined Aluminium Oxide Flap Discs be used on?
They are perfect for metal, mild steel, alloy steel, stainless steel, and non-ferrous metals such as aluminum or copper.
How does it compare to regular aluminium oxide flap discs?
Calcined versions last longer, stay sharper, and run cooler, offering higher efficiency and lower replacement costs over time.
When should I choose Calcined Aluminium Oxide over Zirconia or Ceramic?
If you want a cost-effective upgrade with balanced performance and price, choose calcined aluminium oxide.
For heavier-duty or high-pressure grinding, zirconia or ceramic flap discs are recommended.
