FAQ

 

Q: Brown fused alumina vs white fused alumina, which is better for stainless steel?

A: Brown fused alumina, with its higher toughness and durability, is generally more cost-effective for initial and intermediate polishing of stainless steel. White fused alumina, being sharper and friable, is often preferred for final finishing to achieve a brighter luster.

Q: What is the recommended polishing liquid to slurry ratio?

A: A common starting ratio is 1:5 to 1:10 (powder to water or oil), but it can vary based on the polishing equipment and desired result. Our technical team can provide specific recommendations for your application.

Q: How long is the shelf life of corundum polishing powder?

A: Under dry and sealed conditions, our brown corundum polishing powder can be stored for up to 24 months. It is recommended to avoid humid environment to prevent lumps from affecting the use effect.

Q: Can you provide a customized granularity distribution?

A: Yes, we can provide customized particle size distribution based on your specific needs. Please contact our sales team to discuss your technical requirements.
