Both are anti-microbial but aluminum oxide coating has better scratch resistance.
We performed a micro-scratch resistance test on products finished with ceramic bead coating and aluminum oxide coating and compared the results.
Both finishes performed well, but there was a clear winner. The product finished with ceramic bead coating showed just a few visible scratches after the test while the product finished with aluminum oxide coating showed no visible scratches at all.
Our Modin Collection is topped with an aluminum oxide coating for superior scratch resistance and an anti-microbial finish.
