Brown Corundum for Sandblasting

Brown corundum is a commonly used abrasive in sandblasting. Due to its high hardness, good wear resistance and strong chemical stability, it is widely used in the surface treatment of metal and non-metal materials.

1. Application fields
- Metal surface treatment:
- Rust removal and descaling: used for surface cleaning of materials such as steel, aluminum alloy, etc., to remove rust, welding slag or old coating.
- Pretreatment: Before spraying, electroplating or bonding, sandblasting is used to increase surface roughness and improve adhesion.
- Deburring: Remove burrs or edges after machining to make the surface smooth.

- Non-metal surface treatment:
- Glass and ceramic etching: achieve frosted, matte or pattern engraving effects.
- Stone cleaning: remove dirt or aging layers and restore surface texture.

- Aerospace and automotive industries:
- Used for surface strengthening and cleaning of high-strength materials such as turbine blades and engine parts.

- Mold cleaning:
- Remove residues or release agents on the mold surface to extend the mold life.

--2. Advantages of brown corundum sandblasting
- High hardness (Mohs hardness 9.0): suitable for processing hard materials such as stainless steel, titanium alloy, etc.
- Strong wear resistance: reusable, reducing consumables costs.
- Chemical inertness: does not react with the processed material to avoid pollution.
- Sharp edges: strong cutting force, higher efficiency than abrasives such as quartz sand and glass beads.
- Environmental protection: compared with silica sand, there is no free silica dust, reducing the risk of silicosis.
