Alumina Rod - Ø 12.7mm L 1000mm

Details

SKU: 1000023855 Product Code: AL60-RD-000178
Alumina Rod is composed of high-purity Al₂O₃ ceramic, offering exceptional hardness, high-temperature resistance, and chemical inertness. Its low thermal conductivity and excellent electrical insulation make it ideal for advanced engineering and high-temperature industrial use. The rods are widely applied in aerospace, electronics, metallurgy, and precision instrumentation, where dimensional stability under thermal stress is essential. Specific uses include serving as structural supports in high-temperature furnaces, precision insulators in electronic assemblies, and wear-resistant components in mechanical systems. Withstanding temperatures exceeding 1600 °C without deformation or contamination, Alumina Rod supports consistent performance in aggressive environments. In research and innovation, it facilitates experiments requiring thermal and electrical isolation, enabling the development of new materials and high-performance systems. Its durability, coupled with minimal reactivity, makes it an indispensable material in scientific and industrial applications requiring longevity and purity.
