Product Description
High Temperature Resistance Black Corundum BA Black Fused Alumina
1-3mm Black Aluminum Oxide
Black fused alumina, also known as black aluminum oxide, is a type
of abrasive material that is commonly used in various industrial
applications. It is made from the high-quality bauxite ore by
fusing it in an electric arc furnace at high temperatures. During
this process, the aluminum oxide content in the bauxite is reduced,
resulting in a material that is predominantly composed of aluminum
oxide and iron oxide.Color and Appearance: As the name suggests, black fused alumina is black in color. It
has a matte appearance and a high hardness.
Hardness: Black fused alumina is known for its high hardness, making it
suitable for abrasive applications. It is often used for cutting,
grinding, and polishing metals, ceramics, and other materials.
Abrasive Properties: It is an abrasive material with excellent cutting and grinding
properties. It is used in applications such as sandblasting,
grinding wheels, abrasive belts, and abrasive powders.
Strength and Durability: It has good strength and durability, making it a reliable choice
for applications where wear resistance is essential.
Chemical Composition: Black fused alumina typically contains aluminum oxide (Al2O3) as
the primary component, along with iron oxide (Fe2O3) and small
amounts of other impurities.

finishing processes by removing rust, old paint, scale, and
contaminants.
Cutting:
- Black fused alumina is used as an abrasive material in cutting
wheels or discs for precision cutting of various materials,
including stainless steel, carbon steel, and alloys.
- It provides clean and accurate cuts in manufacturing and
metalworking processes.
Refractory Industry:
- In the refractory industry, black fused alumina is sometimes added
to refractory materials to enhance their properties.
- It can improve the resistance of refractories to high temperatures,
wear, and corrosion, making them more suitable for demanding
applications like furnaces and kilns.
Abrasive Blasting:
- Black fused alumina is used in abrasive blasting cabinets and
systems for cleaning and surface preparation in a variety of
industrial settings.
- It helps remove rust, scale, paint, and other surface contaminants
from metal surfaces.
Lapping and Polishing:
- In precision machining and optics manufacturing, black fused
alumina is used as an abrasive in lapping and polishing processes.
- It assists in achieving flat and highly polished surfaces on
optical lenses, semiconductor wafers, and precision components.
Cutting Tools:
- Some cutting tools, such as cutting discs and abrasive saw blades,
are made with black fused alumina as an abrasive material.
- These tools are used in construction, metalworking, and
fabrication.
Refractory Castables:
- Black fused alumina can be used as an aggregate in the formulation
of refractory castables.
- It improves the overall performance and resistance of these
materials in high-temperature environments.
Abrasive Powders and Compounds:
- Black fused alumina is ground into fine powders and used in
abrasive slurries and compounds for polishing and surface
finishing.
- It is utilized in applications like jewelry making, optics, and
electronics manufacturing.
Tumbling and Deburring:
- It is employed in tumbling and deburring processes to remove burrs
and sharp edges from metal and plastic components, providing a
smooth and finished appearance.
