Alumina zirconia grit (zirconia alumina abrasive) is widely used in heavy‑stock removal, high‑temperature grinding, and aggressive surface treatment industries.
Chemical Composition (Typical Range)
- Al₂O₃ (Aluminum Oxide): 55–75%
- ZrO₂ (Zirconium Dioxide): 25–40%
- SiO₂ (Silica): ≤1.0%
- TiO₂ (Titanium Dioxide): ≤0.5%
- Fe₂O₃ (Iron Oxide): ≤0.2%
- Na₂O (Sodium Oxide): ≤0.1%
Key Industries & Fields
- Metal Fabrication & Welding Industry
- Grinding welds, removing burrs, chamfering
- Deburring and blending on carbon steel, stainless steel, alloy steel
- Automotive & Auto Parts
- Grinding engine parts, camshafts, crankshafts
- Deburring castings, forgings, and machined components
- Aerospace & High‑Temperature Alloys
- Grinding titanium, Inconel, stainless steel, and heat‑resistant alloys
- Heavy‑duty grinding of aircraft components
- Shipbuilding & Offshore Engineering
- Surface preparation (blasting/grinding) for hulls, decks, steel structures
- Removing rust, oxide scale, old coatings
- Steel & Metal Foundry
- Grinding steel billets, slabs, and castings
- Defect grinding and finishing of metal products
- Railroad & Heavy Industry
- Rail grinding, maintenance of heavy machinery
- High‑load grinding tools for construction machinery
- Abrasive Manufacturing
- Making coated abrasives: sanding belts, discs, flap discs
- Making bonded abrasives: grinding wheels, cut-off wheels
- Surface Treatment & Coating Industry
- Sandblasting for adhesion preparation
- Roughening surfaces before painting, powder coating, or thermal spraying
Why it’s preferred in these fields:
- High toughness & heat resistance
- Self‑sharpening during grinding
- Longer tool life than regular alumina
- Ideal for heavy grinding & high pressure
