What Are Fire Bricks?
Fire bricks, or refractory bricks, are specialized materials designed to withstand extreme temperatures (up to 3,000°F/1,650°C) while maintaining structural integrity. They are essential for industrial furnaces, fireplaces, kilns, and pizza ovens.
Types of Fire Bricks
1. High-Alumina Fire Bricks
- Zusammensetzung: 50-90% alumina
- Maximale Temperatur: 2,912°F (1,600°C)
- Anwendungen: Steelmaking, cement rotary kilns
2. Silica Fire Bricks
- Zusammensetzung: 93-96% silica
- Maximale Temperatur: 2,642°F (1,450°C)
- Anwendungen: Glass melting furnaces
3. Insulating Fire Bricks
- Zusammensetzung: Porous ceramic
- Maximale Temperatur: 2,300°F (1,260°C)
- Anwendungen: Backing layers for heat retention
4. Magnesia Fire Bricks
- Zusammensetzung: Magnesium oxide
- Maximale Temperatur: 3,272°F (1,800°C)
- Anwendungen: Non-ferrous metal processing

Price of Fire Bricks: Market Analysis
The price of fire bricks varies based on:
- Material Costs: Alumina prices surged 18% in 2025 due to supply chain constraints.
- Size/Shape: Custom-cut bricks cost 20-35% more than standard sizes.
- Order Volume: Bulk purchases (1,000+ units) reduce per-unit costs by 15-30%.
Regional Price Comparison (Per Piece)
| Region | Hochtonerde | Isolierung |
|---|---|---|
| North America | $3.0–$6.5 | $4.0–$8.5 |
| Europe | $3.2–$7.0 | $4.5–$9.0 |
| Asia | $2.0–$5.0 | $3.0–$6.5 |
Pro Tip: Kerui Refractory offers volume discounts and FOB pricing for orders exceeding 500 units, with ISO 9001-certified quality control.
How to Choose the Right Fire Bricks
- Match Temperature Requirements:
- For >2,500°F, choose magnesia or high-alumina bricks.
- Optimize Thermal Efficiency:
- Pair dense bricks (e.g., Kerui’s KR-75A) with insulating layers.
- Budget Planning:
- High-alumina bricks balance cost ($2.5–$6.0/pc) and performance.
FAQs About Price of Fire Bricks
Q1: What factors most affect the price of fire bricks?
A: Raw material quality (e.g., alumina purity), production method (hand-molded vs. machine-pressed), and shipping distance. Kerui Refractory’s automated production cuts labor costs by 22%, passing savings to buyers.
Q2: Are cheaper fire bricks ($1.5–$2.0/pc) reliable for DIY projects?
A: Low-cost bricks often have ≤40% alumina and crumble above 1,800°F. For home pizza ovens, invest in mid-range bricks ($3.0–$4.5/pc) like Kerui’s KR-50I with a 5-year thermal stability guarantee.
Q3: How to negotiate better prices for bulk fire brick orders?
A: Request FOB quotes, consolidate shipments, and ask about Kerui’s loyalty program (5% credit on annual orders >$20,000).
