Overview
Fire Bricks — what they are, when to specify
Fire bricks (also called firebricks or refractory bricks) are pressed and fired ceramic blocks that line the hot zones of furnaces, kilns, boilers, incinerators and reheating equipment. The grade is set by alumina content, density and the impurity profile (iron, alkali, silica). Get the grade right and the lining lasts longer, runs cooler on the casing, and uses less fuel.
Grades
Stocked grades — pick by service condition
Indicative properties only. Final specification is set per application after we review your operating envelope.
| Grade | Composition | Service Limit | Typical Application |
|---|---|---|---|
| Fireclay (IS-8 Class A/B/C) | 30-42% | 1300-1450 °C | Boiler linings, soaking pits, foundry crucibles |
| Low-Iron Fireclay | 38-45% | 1400-1500 °C | Glass tank checkers, regenerators |
| 60% High-Alumina | 58-62% | 1500-1600 °C | Reheating furnaces, air heaters, ladle backup |
| 70% High-Alumina | 68-72% | 1550-1650 °C | Cement kiln transition zone, lime kilns |
| 80% High-Alumina | 78-82% | 1650-1700 °C | Aluminium melting furnaces, foundry ladles |
| 90% High-Alumina (Sillimanite/Mullite) | 88-92% | 1700-1800 °C | Glass furnace crowns, ceramic kiln roofs |
Standard ISI shapes (Straights, Arches, Wedges, Skews, Tiles) and engineered special shapes per drawing. Bevelled, drilled and tapered shapes available on indent.

Spec advice before quote
Choosing the right grade for the operating envelope makes a much bigger lifecycle-cost difference than haggling on the cheapest grade. Our technical team will recommend by zone before quoting.
ISO 9001:2015 audit-ready
Every batch ships with composition and dimensional QC records, supported by our ISO 9001:2015 certification (Cert. 11553, AQSR / USAC accredited, valid through 17 Sept 2027).
Frequently Asked
Fire Bricks questions, answered
What's the difference between fireclay and high-alumina?
Fireclay bricks are 30-45% alumina — the cost-effective choice for service up to ~1450 °C. High-alumina starts at 60% and rises to 90%+, with each step up extending service temperature, refractoriness-under-load and slag resistance. We will recommend the lowest-alumina grade that meets your operating conditions, since over-specifying alumina is just wasted spend.
Do you supply ISI-marked bricks?
Yes. Standard fireclay and high-alumina grades are supplied to IS-8 and IS-1528 with batch test certificates. We can supply additional third-party test reports on request for project tenders.
Can you cut and grind to special shapes?
Yes. We supply both standard arch/wedge/skew shapes and engineered specials produced from drawings. Tolerance bands and test reports follow the relevant IS standard.
