Frequently Asked Questions

White fused alumina has higher purity (99.5% Al₂O₃) compared to brown fused alumina. WFA has lower iron content, making it ideal for applications requiring clean, contamination-free results like precision polishing and white ceramics.

We offer white fused alumina in various mesh sizes from 12# (coarse) to 320# (fine). Common sizes include 24#, 36#, 46#, 80#, 120#, and 220#. Custom sizing is available upon request.

Store WFA in a dry, cool environment away from moisture. Use sealed containers to prevent contamination. Proper storage ensures consistent performance and extends shelf life indefinitely.

Minimum order quantity varies by mesh size and packaging. Typically 1 ton for standard sizes. Sample quantities available for testing purposes. Contact us for specific requirements.

Yes, white fused alumina can be recycled multiple times in many applications, making it cost-effective and environmentally friendly. Recycling depends on the application and contamination level.
