Alumina Ceramic Bar

Our alumina ceramic bar is made of high‑purity alumina (Al₂O₃ 92%–99.5%) through dry pressing /isostatic pressing and high‑temperature sintering. It features high hardness (Hv≥1500), high temperature resistance up to 1600°C, and excellent insulation (volume resistivity >10¹⁴ Ω・cm). Standard sizes: thickness 1–50mm, width 10–300mm, length ≤600mm (customizable). Widely used for high‑temperature furnace guides, wear liners, electrical insulation supports, replacing metal and plastic to improve equipment stability and service life.

High temperature & oxidation resistance: Stable up to 1200°C (99% alumina up to 1600°C), no deformation. Ideal for melting & sintering furnace guides.

Chemical corrosion resistance: Resists strong acid, alkali, and organic solvents for electroplating & chemical reactor liners.

✅ Outstanding Mechanical Properties

Ultra‑high hardness & مقاومة التآكل: HRA≥85, 10× more wear‑resistant than manganese steel.

High bending strength: ≥300MPa (99% الألومينا), shock‑resistant for heavy equipment.

✅ High Precision & Versatility

Precision dimension control: Tolerance ±0.1mm (precision ground ±0.02mm), Ra≤0.4μm.

Flexible customization: Drilling, chamfering, slotting, metallization (Ni/Ag plating) available.

✅ Excellent Insulation & Thermal Stability

High insulation: Breakdown voltage ≥20kV/mm for high‑voltage electrical equipment.

Controllable thermal conductivity: 30W/m·K, ideal for electronic thermal management.
