Description
Fire Bricks 40% Alumina are high-quality refractory bricks designed to withstand continuous exposure to high temperatures up to 1,400°C. Manufactured from selected fireclay and alumina minerals, these durable bricks combine excellent heat resistance, mechanical strength, and thermal stability, making them ideal for both industrial and domestic applications.
Each brick measures 230 × 115 × 75 mm, a standard size that fits easily in kilns, furnaces, boilers, fireplaces, and pizza ovens. The 40% alumina content provides a balanced mix of insulation and strength, protecting structures from thermal shock and chemical attack. These fire bricks retain shape and integrity even under repeated heating and cooling cycles, ensuring long service life and energy efficiency.
At Gypsum Ceiling Supplies, we supply genuine fire bricks and refractory materials suitable for all heat-intensive applications, from home projects to large industrial installations.
