HERUN Ceramics supplies custom alumina, zirconia, silicon carbide and silicon nitride components for high-wear, high-heat and insulating applications.
A good ceramic part starts with the right material. Use the guide below to narrow choices before confirming shape, tolerance and finish.
Commonly selected for electrical insulators, ceramic rods, tubes, plates, pump parts and fixture components. 95% alumina balances performance and cost; higher-purity alumina improves insulation and chemical reliability.
Zirconia ZrO2
Use for pump seals, shafts, sleeves, medical-style components and parts that need fracture toughness.
Like the reference article, this section gives buyers a technical reason to trust the page: alumina is not just a product name, it is a material family with purity grades, processing choices and application trade-offs.
| Grade | Best For | Trade-off |
|---|---|---|
| 95% Al2O3 | General wear parts, insulators, tubes and rods | Best cost/performance |
| 99% Al2O3 | Higher insulation, cleaner processes, precision parts | Higher cost and harder machining |
| Custom | Special geometry, tolerance or finish requirements | Quote from drawing |
Start from a standard ceramic shape, then specify material, purity, size, tolerance, surface finish and quantity.
Ground or polished rods for guides, plungers, pins and shafts.
Insulating tubes, thermocouple sheaths, spacers and precision sleeves.
Wear plates, insulating substrates and high-temperature supports.
Seal faces, spacers, bearing races and pump components.
Small precision ceramic caps, spray nozzles and custom parts made from drawings or samples.
A broader range of alumina and zirconia parts for wear, insulation, sealing, printing machinery, fixtures and high-temperature equipment.
Multi-hole insulating tubes for high-temperature and electrical applications.
Wear-resistant rods, sealing pins and spray-gun ceramic tips.
Insulating fasteners for fixtures, high-wear assemblies and special equipment.
