Product Description
 |
Our high precision alumina ceramic rod (Al₂O₃ ceramic bar) is custom-made and finely polished for excellent wear resistance. Manufactured from high-purity alumina oxide, this ceramic rod features tight dimensional tolerance, smooth polished surface, high hardness, good corrosion resistance and outstanding insulation performance. |
Features: a) Wear resistant b) Corrosion resistant c) Heat resistant d) Stable dimensions e) Lightweight f) Long performance life |  |
 | We support customized size, shape and surface treatment according to customers’ drawings and technical requirements. These polished Al2O3 ceramic bars are widely used as ceramic shafts, positioning pins, guide rods and wear parts in precision machinery, automation equipment, electronic industry and testing instruments. |
