High Temperature Fire Bricks 40%(Alumina Bricks)

• Heat resistance: Can withstand temperatures from about 1,000 °C up to 1,800 °C depending on grade. • Composition: Typically made from alumina, silica, magnesia, or other refractory materials. • Density & insulation: Available in dense (heavy) types for structural strength and insulating (lightweight) types for thermal insulation. • Shape & size: Usually rectangular like normal bricks, but can also be shaped for specific furnace or kiln designs. • Durability: Resistant to spalling (cracking due to heat changes) and chemical corrosion from slags, ash, or gases.
