Brown Fused Aluminum Oxide Micropowder W Grade 1.99c/cm3 For Polishing Applications
Brown Fused Aluminum Oxide Micropowder W Grade for Polishing Applications
Brown Fused Alumina Product Description
Aluminum oxide is fused in an electric arc furnace which produces a high-strength, tough, and extremely durable grain. Aluminum oxide is useful in many forms. The most common form is brown fused. Brown fused aluminum oxide is a general-purpose, loose grain abrasive that is used in abrasive blasting, polishing, lapping, or other finishing applications.
When blast equipment is paired with a media recovery system, aluminum oxide offers multiple turns/recyclability before it breaks down. Typically propelled by air, aluminum oxide acts as a powerful, multi-edged abrasive that will penetrate the work piece while creating an exceptionally clean and uniquely etched surface. This unique surface finish is excellent preparation for an application of paint or powder coating.
Aluminum oxide can be used on a variety of materials such as ferrous metal, steel, many metal alloys, stainless steel, glass, ceramic, marble, granite, stone, and other hard surfaces.
Applications:
· Abrasive blasting
· Lapping
· Cleaning of investment castings
· Anchor pattern creation for coating or bonding applications
· Surface preparation for thermal spray coatings
· Stone and granite monument lettering
· Glass etching or frosting
· Matte surface finishing
· Anti-skid surfaces
· Paint, coating, scale, rust, or contaminate removal
Physical characteristics:
· Sharp, angular shape
· Hardness is around 9 on the Mohs scale
· Due to hardness and durability, aluminum oxide is generally reusable for multiple turns
· Chemically inert
· High-melting point
· Medium to high bulk density
Macro, micro, and custom grit sizes and blends available
