High Temperature High Alumina Insulation Brick – Lightweight, Energy-Efficient Solution for Industrial Furnaces
Product Overview:
Our Light Weight High Alumina Insulation Brick (also known as high-alumina heat insulating brick) is an essential energy-saving refractory material designed for heat preservation and insulation in various industrial kilns and furnaces. With an alumina oxide (Al₂O₃) content of over 48% and a refractoriness up to 1770°C (working temperature up to 1550°C), it offers superior insulation, low thermal conductivity, and high mechanical strength. Featuring high porosity and low bulk density, it effectively reduces furnace load, minimizes heat loss, and significantly lowers fuel consumption and operational costs.
