Description
Product Description:

Leadsun high alumina bricks are manufactured with high quality selected bauxite chamotte as raw material, processed through advanced molding technology, high temperature sintering and strict quality control system. The main mineral components are corundum and mullite phases, which give the bricks excellent high temperature mechanical strength and chemical corrosion resistance.

Our high alumina bricks are widely used in various thermal industrial furnaces due to their high refractoriness, good thermal shock resistance, great slag erosion resistance and long service life. They are available in different alumina content grades from 60% to 80% to meet different application requirements.

The bricks are produced under strict ISO9001 quality management system, ensuring consistent quality, precise dimensions and reliable performance. With over 15 years of experience in refractory manufacturing, Leadsun has become a trusted supplier for customers worldwide.
