Alumina Rod (≥99% Al₂O₃)

https://www.s4r.fr/web/image/product.template/145/image_1920?unique=79bad65
S4R alumina rods are made from high-purity alumina ceramic (Al₂O₃ ≥99%) and are designed for laboratory, high-temperature, and technical applications requiring excellent thermal stability, chemical resistance, and electrical insulation.

They offer high hardness, good wear resistance, and reliable dimensional stability in demanding environments. Alumina rods are suitable for use as ceramic supports, insulating rods, spacers, positioning elements, structural supports, and high-temperature laboratory components.

Under suitable operating conditions, alumina rods can be used at temperatures up to approximately 1700°C, depending on the application and heating environment.

Custom lengths available on request depending on project requirements.
