White Fused Alumina Supplier
White fused alumina is produced from industrial alumina by electric-arc melting, cooling, crushing, magnetic separation and screening. The catalog covers abrasive grains, aggregate, fines and W micron grades for resin-bonded abrasive and other finishing applications.

Material specification and evaluation
For white fused alumina used in bonded abrasives, distinguish graded abrasive grain, aggregate, fines and micron powder. Apply the data and acceptance requirements for the corresponding grade, rather than treating different size groups as interchangeable.
| Enquiry detail | Information to provide or confirm |
|---|---|
| Grade and particle size | Grade name, grain designation or particle-size distribution, and intended application. |
| Acceptance criteria | Required chemical limits, physical properties, size distribution and grade-specific technical documents. |
| Sample review | Discuss sample quantity, evaluation method, acceptance basis and production-trial conditions before ordering. |
| Supply and packing | Purchase quantity, packaging, destination, required schedule and delivery terms. |
White fused alumina price per ton and quotation basis
Compare prices for the same grade, particle size, quantity and delivery basis. Confirm whether the quoted tonne is a metric tonne, together with currency, validity, packaging, freight inclusions and delivery terms. Request a specification-based quotation rather than applying one grade’s price to another.
Suitability for a cutting or grinding disc depends on the selected grade and manufacturing process. Use grade-specific information and an agreed sample or trial review before confirming the supply specification.
