When it comes to achieving a fine, consistent finish in industrial and DIY applications, 220 grit white aluminum oxide abrasive stands out as a top-tier choice. Known for its sharp cutting edges and purity, this abrasive material is perfect for precision work across a variety of materials including metal, wood, ceramic, and glass. Whether you're polishing, deburring, or preparing a surface for coating, 220 grit provides the optimal balance between smoothness and abrasive power.
White Fuesd Alumina, often referred to as WAO, is a refined form of aluminum oxide that is known for its high purity (over 99%) and sharp, blocky structure. Manufactured through the fusion of high-grade bauxite in an electric arc furnace, this abrasive is prized for its durability, hardness, and ability to fracture under pressure, creating new cutting surfaces.
Its high friability means it breaks down faster than brown aluminum oxide, offering a cooler, cleaner cut, which is especially beneficial for delicate or heat-sensitive materials.
Abrasive grits are classified based on their particle size. The higher the grit number, the finer the particles. 220 grit sits in the middle of the fine grit range, making it ideal for finishing work where a smoother surface is desired without removing too much material.
| Grit Range | Application |
|---|---|
| 40-60 | Heavy material removal |
| 80-120 | Intermediate smoothing |
| 180-240 | Fine finishing |
| 320-600 | Ultra-fine polishing |
The 220 grit size is the perfect middle ground for users who want to balance aggressiveness with surface smoothness. It removes minor imperfections, smooths surfaces between coats of paint or varnish, and prepares surfaces for polishing or coating. It’s particularly ideal for jobs requiring a consistent matte or satin finish.
You can use 220 grit White Fuesd Alumina with a range of equipment, including:
When selecting abrasive grit, consider:
When purchasing 220 grit White Fuesd Alumina, consider:
White Fuesd Alumina is more eco-friendly than many other abrasives. It's inert, non-toxic, and often reusable. Some facilities even offer recycling programs for spent abrasives, reducing landfill waste.
Many industries—from aerospace to fine woodworking—report consistent results with 220 grit White Fuesd Alumina. Users praise its cutting efficiency, minimal dust output, and reusability. One precision metal fabricator shared that switching to 220 grit WAO improved their coating adhesion rates by 35%.
It's used for fine finishing of metal, wood, glass, and ceramics, especially where a smooth surface is required.
Yes, due to its fine grit and high purity, it won't gouge soft metals like brass or aluminum.
Yes, with proper cleaning and inspection, it can be reused several times in blasting applications.
Aluminum oxide is more durable and cuts cleaner than traditional sandpaper, especially in blasting applications.
It generates less dust than coarser abrasives, but proper PPE and ventilation are still required.
Absolutely. It's effective in both, though lifespan and performance may vary depending on the conditions.
220 grit White Fuesd Alumina abrasive is a powerful and versatile material for finishing work in various industries. Its purity, sharpness, and friability make it a top choice for users looking for high-quality surface prep and finishing. Whether you're a professional or a DIY enthusiast, this grit level ensures a balance of efficiency and smooth results. Choose wisely, follow safety practices, and enjoy the performance this superior abrasive offers.
