Mascera provides custom-made alumina ceramic rods with varying purities ranging from 95% to 99.8%. The surface finish of these rods can be as-fired, finely ground, or polished, and their geometry can be machined to meet high fitting requirements with tight tolerances. In addition, threads can be machined on both ends of alumina ceramic rods for fastening purposes. Whether it's a small quantity for a prototype or a large quantity for batch production, our services are always available.

Product detail


Alumina ceramic, also known as Al2O3 ceramic or aluminum oxide ceramic, is a highly versatile technical ceramic material widely used in various industries. It boasts several advantages, including high strength, good dielectric properties, excellent wear resistance, high temperature resistance, and corrosion resistance. It is also one of the hardest and most wear-resistant materials on Earth, requiring diamond tools for machining after sintering.


The fields in which alumina ceramic is applied are extensive and include machinery, electronics, semiconductors, petroleum, chemicals, textiles, and others. Mascera offers tailor-made alumina ceramic rods with varying purities ranging from 95% to 99.8%. The surface finish can be as fired, fine grinding, or polishing, and the geometry can be machined to tight tolerances to meet high fitting requirements. Additionally, threads can be machined on both ends of the alumina ceramic rods for fastening purposes. Whether it's for a small quantity prototype or a large batch production, we are always prepared to provide our services.
