Product Description
Calcined Brown Fused Alumina Flap Discs are manufactured with top quality of abrasive cloth made from heat-treated brown fused alumina. The calcination process make the abrasive grain's crystal structure more stable. It has better character as stronger bonding strength, less internal stress and more consistent grinding performance.
Compared with normal Brown Fused Alumina(BFA), this calcined brown fused alumina flap disc is more fast speed, and longer using life; Also during the grinding process, it will produce less heat and low noise. They are widely used for metal polishing, weld treatment, edge chamfering, general surface cleaning and other applications.
Key Features of Calcined Brown Fused Alumina Flap Disc
Stable and aggressive cutting performance
Heat-treated grains provide uniform hardness and toughness, ensuring smooth grinding without vibration.
The abrasive grains after heat-treatment, it gets uniform hardness and toughness, more stable structure, more consistent cutting performance under high pressure. Also not easy to happen with vibration and unstable grinding.
Longer service life & superior wear resistance
Typically lasts 20–40% longer than standard brown alumina flap discs.
The heat-treated grains is more tough and and has stronger tensile strength. It can make the grains keep longer time with its sharpness.So workers no need to change flap disc so frequently and can reduce process cost.
Low-heat grinding, prevents work-piece from burning
Best for stainless steel and other heat-sensitive metals. Low heat grinding process, can prevent work-piece from out-of shape.
Stronger bonding, less grain shedding
The abrasive grain become more rough, can adhesive more closely to the resin bond.
Wide versatility
Calcined Brown Fused Alumina Flap Disc can be used for SS, carbon steel, cast steel, alloy steel,welding etc. Available in T27 (flat) and T29 (conical) shapes, suitable for most angle grinders.
