5 FAQs of High Hardness Insulation 99% Al2o3 Alumina Ceramic Ring Sleeve Wheel

What’s the max temperature this alumina ceramic ring handles?
It withstands constant heat up to 1650°C (3000°F). Short bursts reach even higher. This makes it ideal for extreme heat areas like furnaces.

How hard is it compared to steel?
It’s much harder. Its rating is HRA 88-90. Typical steel is HRA 60-80. This extreme hardness resists scratches and wear far better.

Will it crack under pressure?
It handles high compression strength, around 2200-2600 MPa. It resists crushing forces well. Avoid sudden impacts or drops. That’s its weak point.

Can its surface be made smooth?
Yes. Precision grinding achieves very smooth finishes. This reduces friction. Smooth surfaces also prevent material sticking during processes.

Why choose alumina over other ceramics?
Alumina offers the best balance for many uses. It combines extreme hardness, high heat tolerance, and good chemical resistance. It’s also cost-effective for industrial needs.
