Zirconium corundum belt PZ533 (Deerfos PZ533 Alternative)

 Zirconium corundum abrasive  belt PZ533 (Deerfos PZ533 Alternative)

Zirconia sanding belts, also known as zirconia abrasive belts or zirconium corundum belts, are a high-performance solution for aggressive grinding and deburring of metal surfaces. Designed specifically for medium to heavy material removal, these belts excel in industrial settings such as small to mid-sized metalworking shops, polishing workshops, and automotive parts manufacturing facilities. With a unique self-sharpening structure and superior toughness, zirconia belts are ideal for use on stainless steel, carbon steel, alloy steel, and cast iron, especially in high-pressure applications.

Key Features of Zirconia Abrasive Belts

• Self-Sharpening Grains: Zirconia alumina features a friable structure that continually fractures during use, exposing fresh cutting edges and maintaining high grinding efficiency.
• High Stock Removal: Excellent for aggressive applications such as weld seam removal, heavy deburring, and oxide/rust layer elimination.
• Long Belt Life: Outlasts aluminum oxide belts by 2–3 times, reducing the frequency of belt change and downtime.
• Cool Grinding Action: The active grinding additives (grinding aids) help reduce heat generation, minimizing the risk of burning workpieces.
• Strong Backing: Reinforced with heavy-duty polyester or Y-weight cloth for stability during high-tension operations.
• Water & Oil Resistant: Suitable for both dry and wet grinding applications, maintaining performance in harsh environments.

Target Applications Zirconia sanding belts are engineered for demanding grinding tasks and are widely used in:

• Weld Seam Removal: Excellent for removing welds from stainless steel tanks, piping, and structural components.
• Deburring Cast and Forged Parts: Ideal for removing flashing and burrs from cast iron and forged alloy components.
• Rust and Oxide Layer Stripping: Quickly eliminates corrosion and scale layers from metal surfaces.
• Metal Surface Preparation: Prepares surfaces for painting, coating, or fine polishing in automotive and fabrication shops.
• Tank and Vessel Manufacturing: Efficient grinding of curved or flat surfaces with wide belt configurations.

Suitable Materials

• Stainless steel (304/316)
• Alloy steel and carbon steel
• Cast iron and gray iron
• High-manganese steel
• Nickel- and chromium-based alloys
• Automotive-grade metal parts

Who Should Use Zirconia Sanding Belts?

• Metal polishing workshops
• Mid-sized metal fabrication plants
• Automotive components manufacturers
• Industrial repair facilities
• Machining shops handling forged or cast components

Advantages for Small and Mid-Sized Businesses
