|---|---|---|---|---|---|---|
≥90 % Al₂O₃ dense corundum-rich refractory | Choose the dense ≥90 % Al₂O₃ corundum-rich quality for service above 1700 °C or where higher strength and slag/alkali resistance are required; firing temperature and price rise significantly. | 1,100 HV | 5 W/m·K | |||
AL80Default ~80 % Al₂O₃ fired high-alumina refractory | Default fired ~80 % Al₂O₃ quality: use for most furnace components, sheaths and setter plates where high-temperature capability and cost have to be balanced. | 3 W/m·K | ||||
~60 % Al₂O₃ mullite/chamotte-bonded refractory | Pick the most economical ~60 % Al₂O₃ mullite/chamotte-bonded quality for medium-temperature kiln linings and supports; avoid strong alkaline slags and sustained service above 1500 °C. | 2 W/m·K | ||||
Lightweight insulating high-alumina | Use the porous lightweight insulating version when low thermal conductivity and low heat storage govern; it tolerates only very low mechanical load and no abrasive gas flow. | 0.35 W/m·K |
What is C-510 High-Alumina Refractory?
C-510 High-Alumina Refractory is a high-alumina ceramic classified under IEC 60672 as C-510, supplied as dense AL60, AL80 and AL90 bodies and as insulating firebrick (IFB). It is specified for continuous high-temperature structural service to 1650 °C in pressed, extruded and cast shapes such as tubes, linings and supports. The material is brittle and effectively unmachinable after firing (machinability score 5), with 3 W/m·K thermal conductivity and a 100 GPa modulus, so assemblies must allow expansion clearance. Dense sintered 99 % alumina is the alternative where higher strength and purity are needed. C-510 High-Alumina Refractory has a density of 2.9 g/cm³ (0.105 lb/in³), lighter than 76% of ceramic grades. It melts at 1,800°C (3,272 °F). The elastic modulus is 100 GPa (14.5 Msi).

Working with C-510 High-Alumina Refractory
Is C-510 High-Alumina Refractory easy to machine?
In the green or bisque state, turning, milling and drilling with conventional tooling are practical; leave 2–3 % for firing shrinkage. After firing, only diamond grinding or waterjet cutting is feasible and drilled holes chip at breakout.
Can C-510 High-Alumina Refractory be welded?
Not weldable; join with high-alumina refractory cement, mechanical clamping, or a compliant fit to metal parts that includes an expansion gap.
Can C-510 High-Alumina Refractory be formed, bent or molded?
Dry pressing, isostatic pressing, plastic extrusion or casting are the usual routes, followed by firing at 1450–1800 °C in gas or electric kilns; control heating and cooling rates to prevent thermal cracking.
