Product Description
High Purity Alumina Ceramic Rod 95% 99% Al₂O₃ Solid Ceramic Shaft for High Temperature Insulation
Alumina ceramic part is produced by firing a tightly packed powder form of Al2O3 which includes some binder material. Commercially available grades range from 90% up to 99.95% with the higher purity generating somewhat higher hardness. It is possible to machine alumina using diamond grinding techniques. Polishing is also possible, with the degree attainable affected by alumina grain size and production technique, like pressed or extruded.
Alumina ceramic shaped parts are industrial ceramic components made primarily from aluminum oxide (Al₂O₃) and formed into custom, complex, or irregular geometries. Unlike standard ceramic plates or rods, these parts are engineered to match specific applications, tolerances, and performance requirements.
Alumina Rods:
Made of high‑grade Al₂O₃ ceramic material, this solid alumina rod delivers excellent high‑temperature resistance, superior electrical insulation and great wear performance. Available in 95%, 99%, 99.7% purity grades. Supports custom turning, threading and end‑face finishing. Widely used as insulating shafts, sensor components and wear‑resistant parts for furnace, metallurgy and electronic industries.
