Abrasive classification
The flap disc's abrasive classification refers to the type of abrasive used in the disc's manufacturing. There are four main types of abrasives used in flap discs: ceramic, zirconia alumina, aluminum oxide, and silicon carbide.
Ceramic abrasive is the most advanced and most potent abrasive and is used for heavy-duty applications, including metal fabrication, welding, and industrial grinding.
Zirconia alumina is the second most potent abrasive and is ideal for general-purpose metal grinding and finishing.
Aluminum oxide is a versatile abrasive and is suitable for light and moderate grinding applications.
Silicon carbide abrasive is the least potent abrasive and is used for sanding and finishing applications on both metal and non-metallic materials.
Backing classification
The backing of the flap disc also plays a significant role in determining its effectiveness. There are three main types of backing used in flap discs: plastic, fiberglass, and cloth.
Plastic backing is the least durable and is suitable for light-duty applications.
Fiberglass backing is much stronger than plastic backing and is ideal for heavy-duty grinding applications.
Cloth backing is the most durable and ideal for heavy-duty applications like metal fabrication and welding.
