Choosing Flap Disc Material

The choice of Flap Disc material generally depends on the application and the workpiece material during the process. Here are a few common types of Flap Disc materials:

  1.CERAMIC ALUMINA

If you are looking for the best performance in your flap discs application, ceramic is a good choice. The ceramic particles microcrack as they grind, constantly exposing sharp edges and maintaining a high cut rate for the life of the disc. It is ideal for workpieces made of standard steel, tool steel, armor steel, titanium, high nickel alloys, stainless steel, and aluminum, and excels on difficult-to-grind metals.

Combined with a topcoat, ceramic alumina provides fast cutting speeds and low grinding temperatures, helping to protect valuable heat-sensitive components and prevent thermal discoloration of workpieces. The topcoat also helps prevent soft alloy loading, where pieces of workpiece material build up on the Flap Disc. Our YANDISC Ceramic options are surface-coated and stain-free, so they perform exceptionally well on stainless steel.

  2. ZIRCONIA ALUMINA

Flap Disc made of 100% zirconia alumina allow for power cutting and high-performance edge grinding. Zirconia alumina is self-sharpening and excels at high temperatures and pressures. With proper use and maintenance, it cuts fast and lasts a long time. It is ideal for workpieces made of cast iron, carbon steel, structural steel and stainless steel. If you are looking for 100% Zirconia Alumina, our YANDISC FLAP DISC is a great choice.

  3.CERAMIC ALUMINA/ZIRCONIA ALUMINA BLEND

A blend of ceramic alumina and zirconia alumina provides fast grinding, reliable performance and long disc life. This grain combination takes less effort than many others. With a non-contaminating compound, our FLAP discs are ideal for surface grinding, especially on workpieces made of structural steel, carbon steel, stainless steel and cast iron.

  4. ALUMINUM OXIDE

Discs made of aluminum oxide have hard, durable grains and a strong initial stock removal rate, and provide fast cutting and consistent performance. Alumina is ideal for workpieces made of materials such as steel and cast iron and is versatile. However, it’s not shelf sharpening — its single crystal dulls with use. Overall, it offers a combination of performance and value.
