Factory Direct White Corundum Abrasive is a high-purity aluminum oxide abrasive with a minimum Al2O3 content of 99%, produced by electrofusion of calcined alumina. It is available in grit sizes ranging from F4 to F220, with particle morphology shaped by controlled cooling to ensure consistent fracture patterns during grinding. The material exhibits low thermal expansion and high chemical inertness, making it suitable for applications requiring thermal stability under high-pressure conditions.
This abrasive is distinguished by its high hardness and self-sharpening properties, which reduce wheel loading and extend tool life. Unlike brown corundum, it contains minimal iron and titanium impurities, resulting in a cleaner finish on stainless steel and high-alloy surfaces. It is commonly used in bonded wheels for high-speed grinding of tool steels, in coated abrasives for precision polishing, and as a refractory aggregate in kiln furniture and furnace linings. The product is not coated or treated, preserving its intrinsic abrasive performance.
Buyers in metalworking, foundries, and surface treatment industries source this material for its reliability in automated grinding lines. Packaging is typically in 25kg multi-wall paper bags or bulk flexitanks, with custom sizes available on request. Lead times for standard orders are 15 to 25 days from Ningxia, and Incoterms commonly offered are FOB Tianjin or CIF destination port. Buyers should confirm particle size distribution and magnetic content per batch for consistent process performance.
| Chemical Composition | Al2O3 99%+, Fe2O3 <0.2%, SiO2 <0.3%, TiO2 <0.1% |
| Grit Size Range | F4 to F220, per ANSI B74.18 standard |
| Hardness | Mohs 9, Vickers ~2200 HV |
| Bulk Density | 1.65 to 1.80 g/cm³, typical for white fused alumina |
| True Density | 3.95 g/cm³ |
| Particle Shape | Sub-angular to rounded, typical of electrofused alumina after controlled cooling |
| Magnetic Content | Typical <50 ppm, verified by magnet separation test |
| Thermal Stability | Stable up to 1900°C, standard for high-purity alumina abrasives |
| Packaging | 25kg multi-wall paper bags, palletised, or bulk flexitanks |
| Moisture Content | Typical <0.5%, dried post-fusion to prevent clumping |
Ningxia Tengyuan Activated Carbon Co., Ltd. is based in Shizuishan, Ningxia, and operates as a manufacturer of industrial abrasives and activated carbon products. The company's profile indicates production capacity in fused alumina, though no details on plant size, workforce, or export history are provided. Its trust tier is listed as harbor, suggesting verified shipping documentation, but response rate and average response time are zero, indicating no active communication channels on the platform.
The supplier does not claim certifications such as ISO, SGS, or ASTM, nor does it list client names, years in operation, or revenue. It presents itself as a direct producer of white corundum, with product specifications aligned to international grit standards. Buyers should request batch-specific test reports for chemical composition and particle distribution before placing bulk orders, as no public quality assurance documentation is referenced.
Factory direct white corundum (white fused alumina) is a high-quality aluminum oxide abrasive powder widely used in bonded and coated abrasives, surface preparation, and refractory applications. Available in standard grit sizes from F36 to F1200, this industrial-grade material offers consistent hardness and thermal stability for grinding, cutting, and polishing operations. Ideal for B2B buyers seeking reliable abrasive raw material for metalworking, foundries, and surface treatment industries at competitive export pricing.

Sourcing Factory Direct White Corundum Abrasive from Ningxia Tengyuan Activated Carbon Co., Ltd. - China Import Guide
Before ordering, verify the chemical composition report for Al2O3 content and trace impurities like Fe2O3 and TiO2, as these affect surface finish and tool life. Request a sample batch with certified particle size distribution using laser diffraction or sieve analysis. Confirm that the material is not contaminated with recycled or mixed abrasives, which can compromise performance in high-precision grinding applications.
Lead time is typically 15 to 25 days from Ningxia, depending on order volume and port availability. Incoterms are commonly FOB Tianjin or CIF, but buyers should confirm whether the supplier handles export documentation and customs clearance. Payment terms often require 30% advance and 70% against copy of B/L, though letters of credit may be negotiable for first-time buyers.
Quality inspection should include checks for moisture content, magnetic impurities, and particle shape. Request batch-specific test reports for each shipment. For coated abrasives, validate that the abrasive does not contain surface contaminants that interfere with resin bonding. Consider third-party inspection at origin if ordering over 5 metric tons to ensure compliance with technical specifications.
