Metallographic Cut-off Wheel 350×2.5×32mm WA80 – Product Manual
Overview: Luoyang Weixiang Abrasives Co., Ltd. manufactures precision cut-off wheels for metallographic sample preparation. The 350×2.5×32mm WA80 wheel features white fused alumina (WA) abrasive with resin bond, designed for laboratory cut-off machines.
Specifications: 350mm diameter × 2.5mm thickness × 32mm bore; White Fused Alumina abrasive; 80 grit; Resin bond; Type T41; ≥50m/s linear speed; 25 pcs/box.
Material & Process: High-purity WA abrasive provides stable self-sharpening for ferrous metals. High-strength resin bond ensures minimal heat generation and low heat-affected zone. 2.5mm thin design reduces material loss.
Applications: Suitable for carbon steel, alloy structural steel, tool steel, bearing steel (annealed), and cast iron within HRC 20-45 range. For HRC >50 hardened steels, chromium alumina or monocrystalline alumina wheels are recommended.
Key Features: Sharp cutting with minimal breakage; Low heat-affected zone preserving sample microstructure; Dry and wet cutting compatible; Consistent cut quality with minimal burr.
Usage Guidelines: Inspect wheel for cracks before use; Do not use damaged wheels. Mount with proper flanges, tighten evenly without excessive force. Run at idle for 1 minute before cutting. Secure specimen firmly. Feed uniformly without forcing. Maintain continuous coolant supply for wet cutting. Wear eye protection; maintain ≥50cm safe distance from wheel.
Storage: Store in dry, frost-free conditions away from moisture and temperature extremes. Keep flat, do not expose to alkalis. Use FIFO, observe expiration date.
Customization: Custom dimensions, abrasive types, grit sizes, and packaging available. Standard lead time 3-7 working days; custom orders 15-30 working days.

In industrial surface treatment, the selection of blasting abrasives directly affects processing efficiency, surface quality, and overall cost. Brown Fused Alumina, White Fused Alumina, and Black Fused Alumina are three commonly used corundum-type abrasives. Due to differences in smelting raw materials and processes, they exhibit significant variations in chemical purity, physical properties, and application scenarios. Based on technical indicators, this article systematically reviews the selection logic of the three.
